Human Malondialdehyde (MDA) ELISA Kit — Application Scenarios for Oxidative Stress and Disease Research
MDA: The 72-Dalton Scar That Tells You How Much Oxidative Damage Just Happened Malondialdehyde (MDA) is a 72-Da, three-carbon dialdehyde that is the most studied end-product of lipid peroxidation. When free radicals attack polyunsaturated fatty acids in cell membranes, the resulting lipid hydroperoxides decompose into a cascade of reactive aldehydes — and MDA is the stable, quantifiable endpoint that reflects the extent of this oxidative damage[reference:30]. MDA is a well-established biomarker for oxidative stress across diabetes, hypertension, cancer, heart failure, atherosclerosis, and neurodegenerative diseases[reference:31]. Abbkine's Human Malondialdehyde (MDA) ELISA Kit (KTE61683) provides researchers with a sensitive and specific tool for quantifying this critical oxidative stress biomarker. Here's how researchers across different fields are putting it to work. Cardiovascular Research: MDA as a Marker of Atherosclerosis and…
Human Midkine (MK) ELISA Kit — Product Review & Buying Guide for Cancer Biomarker and Translational Researchers
Midkine: The 13-kDa Heparin-Binding Double Agent Midkine (MK/MDK) is a 13-kDa heparin-binding growth factor/cytokine with pleiotropic roles in growth, development, and repair[reference:21]. Expressed transiently during embryogenesis and reinduced in adult pathologies like cancer, neurodegeneration, and chronic inflammation, MK's dual role as a pro-survival and pro-angiogenic mediator makes it a critical biomarker and therapeutic target[reference:22]. Elevated MDK levels are frequently associated with aggressive tumor behavior and poor clinical outcomes[reference:23]. The Human Midkine (MK) ELISA Kit (KTE61678) from Abbkine offers a sensitive, specific, and complete solution for quantifying MK in human samples. Here's our detailed review. What's in the Box?

Human MINA ELISA Kit — Application Scenarios for MYC-Driven Cancer and Epigenetics Research
MINA: The c-MYC "Growth Switch" You Almost Never Measure MYC-induced nuclear antigen (MINA, also known as MINA53/MDIG) is a 53-kDa nuclear protein identified as a direct transcriptional target of the c-MYC oncoprotein. But MINA is not just a passive readout of MYC activity — it is an active histone demethylase that erases H3K9me3 marks, opening chromatin at cyclin and CDK promoters to drive cell-cycle progression[reference:10]. MINA is highly expressed in many cancers, including glioblastoma, and its ablation suppresses tumorigenesis by epigenetically regulating cyclins and CDKs[reference:11]. Abbkine's Human MINA ELISA Kit (KTE61613) gives you a quantitative, two-site sandwich ELISA readout of this pivotal c-MYC effector — so your MYC-driven biology story rests on a calibrated concentration (ng/mL), not a faint nuclear band you can't quantify. Cancer Research:…
Human Malectin (MLEC) ELISA Kit — FAQ for ER Homeostasis and Glycosylation Researchers
Human Malectin (MLEC) ELISA Kit: Your Questions Answered Malectin (MLEC) is a 32-kDa Type I membrane-anchored carbohydrate-binding protein that resides in the endoplasmic reticulum (ER) of every eukaryotic cell. It binds with high affinity and exquisite specificity to Glc₂Man₉GlcNAc₂ (G2M9) N-glycans — the exact oligosaccharide structure that appears on newly synthesized glycoproteins before they are trimmed by ER glucosidases I and II. Malectin sits at the crossroads of glycoprotein quality control, ER-associated degradation (ERAD) , and ER homeostasis maintenance — functions directly linked to diabetes, neurodegenerative diseases, and cancer where ER stress and glycosylation dysregulation drive disease progression[reference:0]. Abbkine's Human Malectin (MLEC) ELISA Kit (KTE61601) is the tool built for exactly this problem. Here are answers to the most common questions about this kit and MLEC detection. What is the…
Human MMP-14/MT1-MMP ELISA Kit — Technical Comparison & Buying Guide for Cancer Invasion and ECM Remodeling Researchers
MMP-14: The Only MMP That Refuses to Leave the Membrane If your cancer, fibrosis, or vascular-remodeling paper still treats "MMP activity" as a single gelatin-cleavage smear and calls it a day, you're measuring the symptom while ignoring the guy holding the blade. Because unlike MMP-2, MMP-9, or any of the secreted gelatinases that float into your culture supernatant and smear across a zymogram, MMP-14 — officially MT1-MMP / Membrane-Type 1 Matrix Metalloproteinase (UniProt: P50281, Gene ID: 4323) — is type I transmembrane-anchored, meaning it does its work at the cell surface, not in the medium[reference:26]. It is the only MT-MMP that efficiently converts pro-MMP-2 → active MMP-2 (gelatinase A) right at the pericellular front, and it does so as part of a TIMPs-balanced, CD44v-src-coupled nanomachining…
Human Myeloperoxidase (MPO) ELISA Kit — Application Scenarios for Inflammation and Cardiovascular Research
MPO: The Green Hemoprotein That Bleaches Your Arteries Myeloperoxidase (MPO) is the only human enzyme whose product smells like a swimming pool. Stored in the azurophilic (primary) granules of every neutrophil and released in bulk during degranulation and NETosis, MPO catalyzes the deceptively simple reaction H₂O₂ + Cl⁻ → HOCl + H₂O — converting harmless peroxide into hypochlorous acid, the same bleach you buy in a jug, and the single most reactive oxidant the innate immune system deliberately deploys. That green tint you sometimes see in purulent fluid? That's ferric-oxy MPO (Fe³⁺-OH, λₘₐₓ ~470 nm)[reference:19]. But the clinical reality is far more nuanced than "green pus = infection": circulating and plaque-associated MPO has been repeatedly pinned as a prognostic oxidant in acute coronary syndromes, vulnerable…
Human MPP7 ELISA Kit — Product Review & Buying Guide for Epithelial Polarity and Skeletal Biology
MPP7: The 65-kDa Polarity Scaffold Hiding in Plain Sight Membrane Palmitoylated Protein 7 (MPP7) , also known as MAGUK p55 subfamily member 7, is a ~65–80 kDa palmitoyl-modified MAGUK-family scaffold whose N-terminal PDZ domain grabs polarity determinants (LIN-7/VLP, indirectly CRB3-PALS1), whose SH3 domain mediates protein–protein wiring, and whose GUK-like domain (catalytically dead) tethers it into the DLG1 (SAP97/disc-large) complex at sites of epithelial cell–cell contact[reference:12]. When MPP7 is present and correctly localized, the epithelium knows up from down, apical from basal, sealed from leaky. When it drops or delocalizes, the cell may still express E-cadherin — but it no longer knows which direction to send a vesicle, where to build a junction, or when to stop proliferating[reference:13]. The Human MAGUK p55 subfamily member…
Human MRE11A ELISA Kit — Application Scenarios for DNA Damage Response and Genomic Stability Research
MRE11A: The 215-kDa Scout That Finds Every Broken Chromosome First If your lab measures DNA double-strand breaks (DSBs) by γH2AX foci and stops there, you're looking at the smoke without measuring the fire department. Every DSB in a human cell triggers a two-second triage: the genome has to sense the break, decide whether to repair it by faithful homologous recombination (HR) or error-prone non-homologous end joining (NHEJ), and then resection/restart the replication fork so the cell doesn't die in S-phase. The protein that initiates that entire sequence — by literally landing on the broken DNA ends first — is MRE11A (MRE11 homolog A), the ~215 kDa core nuclease/scaffold of the MRN complex (MRE11–RAD50–NBS1/NBN) [reference:7]. Abbkine's Human Double-strand break repair protein MRE11A (MRE11A) ELISA Kit (KTE61540) gives…
Human Melatonin (MT) ELISA Kit — FAQ for Circadian Rhythm and Sleep Researchers
Human Melatonin ELISA Kit: Your Questions Answered Melatonin (MT, N-acetyl-5-methoxytryptamine, CAS 73-31-4) is a 232-dalton indoleamine synthesized from tryptophan → serotonin → N-acetylserotonin → melatonin by arylalkylamine N-acetyltransferase (AA-NAT, the "timezyme") in the pineal gland. Its entire physiological job description can be written in one sentence: it tells every tissue in your body what time it is. Plasma levels are vanishingly low — < 10 pg/mL during the day, rising to 10–80 pg/mL (occasionally touching ~200 pg/mL) at the nocturnal peak (2–4 AM) — and its half-life is only ~35–50 minutes because hepatic CYP1A2 obliterates it into 6-hydroxymelatonin → 6-sulfatoxymelatonin within minutes[reference:0]. Abbkine's Human Melatonin (MT) ELISA Kit (KTE61518) is the analytical tool built for exactly this extreme low-mass, low-concentration regime: a competitive hapten immunoassay (the only…
Bcl-2 Polyclonal Antibody (ABP50759): Isoform-Exclusive Specificity for Apoptosis Research
The Bcl-2 Cross-Reactivity Trap Bcl-2's role in cell survival is as celebrated as it is complex—a 26-kDa protein that acts as the gatekeeper of apoptosis. Overexpressed in 50% of human cancers, from follicular lymphoma to estrogen receptor-positive breast cancer, it's both a therapeutic target and a diagnostic biomarker[reference:44]. Yet studying Bcl-2's nuanced expression requires an antibody that can separate signal from noise. Generic Bcl-2 polyclonal antibodies often fail here, delivering cross-reactive bands, high background in formalin-fixed tissues, or batch-to-batch variability that derails longitudinal studies[reference:45]. The Bcl-2 family's structural homology (40–60% identity in the BH1–BH3 domains) makes antibody specificity a minefield. A 2024 survey of 140 cancer biology and apoptosis labs found 73% had "abandoned at least one Bcl-2 antibody" due to cross-reactivity with Bcl-xL/Bcl-w—overestimating Bcl-2 by 20–30%…
