EliKine™ Mouse TNF-α ELISA Kit (KTE7015) — Product Review & Buying Guide for Inflammatory Disease Researchers
TNF-α: The 17-kDa Cytokine That Built an Entire Drug Class Tumor necrosis factor-alpha (TNF-α) is the prototypical pro-inflammatory cytokine — the molecule that proved, beyond any doubt, that neutralizing a single cytokine can reverse human disease. TNF-α drives the inflammatory cascade in rheumatoid arthritis, inflammatory bowel disease, psoriasis, and sepsis, and anti-TNF biologics (infliximab, adalimumab, etanercept) are among the most successful drugs in the history of immunology. In mouse models, TNF-α is the central node that researchers measure to answer three questions: Is this intervention anti-inflammatory? Does it work through TNF-α suppression? And is the effect large enough to matter? Direct evidence demonstrates a predominant role of TNF-α in mouse models of chronic intestinal inflammation, and TNF blockade remains a mechanistic benchmark for…
EliKine™ Mouse TGF-β1 ELISA Kit (KTE7014) — FAQ for Fibrosis and Immune Tolerance Researchers
EliKine™ Mouse TGF-β1 ELISA Kit: Your Questions Answered Transforming growth factor beta-1 (TGF-β1) is the cytokine that does everything — and therefore the cytokine that is most often measured incorrectly. It drives fibrosis, suppresses immune responses, maintains T cell tolerance, and regulates virtually every cell type in the body. The inappropriate presence of active TGF-β1 is implicated in a variety of pathological conditions, from pulmonary fibrosis to cancer immune evasion[reference:20]. But here is the catch that separates a publishable TGF-β1 dataset from a frustrating one: TGF-β1 is secreted in a latent, inactive complex. It is non-covalently associated with latency-associated peptide (LAP) , which renders TGF-β1 inactive and inaccessible to anti-TGF-β antibodies[reference:21][reference:22]. If you measure your sample without activating it, you are measuring only the tiny…
EliKine™ Mouse IL-6 ELISA Kit (KTE7009) — Product Review & Buying Guide for Inflammation and Autoimmunity Researchers
IL-6: The Cytokine That Refuses to Pick a Side Interleukin-6 (IL-6) is the most frustratingly bipolar cytokine in immunology. It is pro-inflammatory in one context (driving fever, acute-phase responses, and Th17 differentiation) and tissue-protective in another (reducing cartilage destruction in experimental arthritis, restraining Th1 responses in Sjögren's-like models, and exerting renoprotective effects in diabetic kidney disease)[reference:10]. This context-dependent duality is precisely why IL-6 must be measured, not assumed — and why the quality of your ELISA matters more than for a cytokine with a single, predictable behavior. In mouse models, IL-6 is produced by an astonishing range of cell types: T cells, monocytes/macrophages, fibroblasts, hepatocytes, vascular endothelial cells, and even tumor cells[reference:11]. That diversity of sources means your sample matrix — whether it is serum,…
EliKine™ Mouse IL-4 ELISA Kit (KTE7007) — Product Review & Buying Guide for Th2 Immunity Researchers
IL-4: The 15-kDa Cytokine That Decides Whether Your Immune Response Goes Th2 Interleukin-4 (IL-4) is a pleiotropic cytokine produced primarily by activated T lymphocytes, mast cells, and basophils. Its biological job description is deceptively simple: it is the master switch for Th2 differentiation. IL-4 drives precursor T helper cells toward the Th2 subset, which mediates humoral immunity, modulates antibody production (including IgE class switching), and coordinates allergic inflammation and anti-helminth defense[reference:0]. In mouse models, IL-4 is the readout researchers use to answer a single, high-stakes question: did this intervention push the immune system toward or away from Th2? Whether you are testing a novel adjuvant, evaluating an allergy therapeutic, or dissecting the cellular sources of type 2 immunity, IL-4 quantification is not optional —…
EliKine™ Mouse IL-17 ELISA Kit (KTE7012) — FAQ for Th17 and Autoimmune Disease Researchers
EliKine™ Mouse IL-17 ELISA Kit: Your Questions Answered Interleukin-17 (IL-17) is the signature cytokine of Th17 cells, γδ T cells, and innate lymphoid cells, orchestrating inflammatory responses through neutrophil recruitment, antimicrobial defense, and autoimmune pathology[reference:47]. In mouse models, IL-17 quantification is essential for studies ranging from experimental autoimmune encephalomyelitis (EAE) to fungal infection models[reference:48]. Clinical benefits from targeting Th17 cell–related cytokines such as IL-17 and IL-23 have validated Th17 biology as a translationally relevant therapeutic axis in multiple sclerosis, IBD, and psoriasis[reference:49]. Yet translating IL-17's biological significance into reliable data remains a hurdle — one that traditional ELISA kits often fail to clear. Abbkine's EliKine™ Mouse IL-17 ELISA Kit (KTE7012) addresses this gap with a design rooted in cytokine-specific biology. Here are answers to the most common questions about…
Mouse TL1/TL1A ELISA Kit (KTE70114) — Technical Comparison & Buying Guide for IBD and Immuno-Oncology Researchers
TL1/TL1A: The TNF-Family Ligand That Moonlights as a Vascular Brake and a Gut T-Cell Accelerator TL1 (TNF-like ligand 1) — interchangeably called TL1A in most literature — is encoded by the Tnfsf15 gene (UniProt: Q5D8E6, Gene ID: 83447) and shares ~72% amino acid identity with human TNFSF15[reference:36]. Unlike its cousin TNF-α, TL1 carries none of the classic "storm" baggage: it doesn't trigger the first-wave pyrogenic spike in sepsis, and it doesn't directly drive caspase-8-dependent apoptosis[reference:37]. Instead, it moonlights as a vascular endothelial growth inhibitor (VEGI) at low concentrations while simultaneously acting as a potent co-stimulatory accelerator for DR3⁺ T cells in the gut lamina propria — a duality that makes it the hidden driver of Crohn's severity, tumor vascular normalization, and even PD-1 checkpoint resistance[reference:38]. Genetic variants in TNFSF15 further support a…
EliKine™ Mouse IL-10 ELISA Kit (KTE7010) — Product Review & Buying Guide for Immune Regulation Researchers
IL-10: The "Master Anti-Inflammatory Cytokine" That Decides Whether Inflammation Resolves or Rages Interleukin-10 (IL-10) is the cytokine that tells the immune system to stand down. Produced by Th2 cells, B cells, activated macrophages, and regulatory T cells, IL-10 tempers excessive pro-inflammatory responses while promoting tissue repair and immune tolerance[reference:24]. Its main biological function is the limitation and termination of inflammatory responses and the regulation of differentiation and proliferation of T cells, B cells, and natural killer cells[reference:25]. In murine preclinical models, IL-10 is a cornerstone biomarker for autoimmune diseases, infection resolution, and tumor immunity[reference:26]. Yet quantifying mouse IL-10 accurately has long plagued researchers: traditional methods lack specificity for murine IL-10, struggle with low-abundance samples, or fail to accommodate diverse sample types[reference:27]. The EliKine™ Mouse IL-10 ELISA…
Mouse TRPM4 ELISA Kit (KTE70054) — Technical Comparison & Buying Guide for Cardiovascular and Immune Physiology Researchers
TRPM4: The 1,040-Amino-Acid Channel That Decides Whether a Cell Fires or Stays Silent Transient receptor potential cation channel subfamily M member 4 (TRPM4) is a calcium-activated, non-selective cation channel that governs membrane depolarization across an astonishing range of cell types. In cardiomyocytes, it regulates heartbeat rhythm; in neurons, it modulates excitability; in immune cells, it shapes inflammatory responses[reference:7]. TRPM4 is implicated in immune function, insulin secretion, cerebral artery myogenic tone, capillary fragmentation, and respiratory rhythm regulation[reference:8]. Mutations in TRPM4 are linked to human hereditary cardiac and skin diseases[reference:9]. Yet studying TRPM4 in mouse models has been a persistent headache. It is a membrane protein — tricky to extract without losing epitopes — and it shares 30–50% sequence identity with other TRPM family members in their transmembrane domains, leading to 15–30%…
Mouse TSLP ELISA Kit (KTE70050) — Application Scenarios for Atopic Dermatitis and Epithelial Immunology Research
TSLP: The Epithelial Alarm That Wakes Up the Entire Type 2 Cascade Thymic stromal lymphopoietin (TSLP) is not a classical cytokine that waits for an immune cell to find it. It is an epithelial-derived alarmin — a danger signal released within minutes when the skin barrier cracks, the airway epithelium encounters allergens, or the gut lining is stressed[reference:0]. Once released, TSLP binds its heterodimeric receptor (TSLPR/IL-7Rα) on dendritic cells, mast cells, and innate lymphoid cells, triggering the Th2-biased immune activation that defines atopic dermatitis, bronchial asthma, allergic rhinitis, and eosinophilic esophagitis[reference:1]. In mouse models, TSLP is the molecular switch that researchers use to ask: did this intervention actually calm the epithelium, or did it just suppress the downstream inflammation? The Mouse Thymic Stromal Lymphopoietin (TSLP) ELISA Kit (KTE70050) from…
Mouse UCP1 ELISA Kit — Technical Comparison & Buying Guide for Thermogenesis and Metabolic Researchers
UCP1: The 32-kDa Proton Leak That Burns Fat Without Shivering Uncoupling protein 1 (UCP1, thermogenin) is the defining molecular marker of brown adipose tissue (BAT) and beige adipocytes — the specialized fat depots that burn chemical energy as heat instead of storing it. UCP1 sits in the inner mitochondrial membrane and provides a proton leak pathway that bypasses ATP synthase, uncoupling oxidative phosphorylation from ATP production and releasing energy as heat[reference:43]. Since metabolically active BAT/beige fat was detected in adult humans in 2009, the field has exploded: researchers are racing to find ways to enhance BAT thermogenesis as a strategy for increasing energy expenditure and combating obesity[reference:44]. UCP1 protein levels are the gold-standard readout for brown/beige adipocyte differentiation, cold-induced thermogenesis, and diet-induced thermogenic capacity[reference:45]. Yet quantifying UCP1 in mouse tissues has remained…
