IL-6 Polyclonal Antibody (Abbkine ABP0137): Cutting Through Inflammation Noise with a Kit That Actually Works
Interleukin-6 (IL-6), the pleiotropic cytokine that orchestrates acute inflammation, B cell differentiation, and even mood regulation, is a double-edged sword—essential for host defense but catastrophic when overproduced in sepsis, rheumatoid arthritis, or cytokine storms. Yet measuring its fleeting surges (0.5–100 pg/mL in serum, spiking to 1,000 pg/mL in acute inflammation) has been a nightmare for labs. Traditional antibodies drown in cross-reactivity with IL-11 or GM-CSF, miss low-abundance signals in early sepsis, or demand 50+ µL of precious patient samples. That’s where Abbkine’s IL-6 Polyclonal Antibody (Catalog #ABP0137) steps in, turning IL-6-specific detection from a guessing game into a data-driven pursuit. Let’s be real: The field of IL-6 antibody research is stuck in the dark ages. A 2024 survey of 160…
p21 Polyclonal Antibody (Abbkine ABP0108): A Practical Guide to Unlocking Cell Cycle Arrest Insights
Navigating the complexities of cell cycle regulation often hinges on one key checkpoint protein: p21 (CDKN1A). As a master regulator of G1/S transition, p21 responds to DNA damage, oncogenic stress, and senescence signals—making it indispensable in cancer, aging, and therapeutic resistance research. Yet, for many labs, translating p21’s biological significance into reliable data remains a headache. Antibodies that claim “high specificity” often falter in low-expression models (e.g., quiescent cells), produce smeared Western blot bands, or fail in formalin-fixed paraffin-embedded (FFPE) tissues where epitopes are masked. Enter Abbkine’s p21 Polyclonal Antibody (Catalog #ABP0108)—a tool designed to turn p21 detection from a variable chore into a consistent, insightful process. If you’ve ever struggled with inconsistent p21 detection in your experiments, you’re not…
Abbkine ERα Polyclonal Antibody (ABP0086): A Precision Tool for Non-Phosphorylated Y537 ERα Detection in Reproductive and Cancer Biology
Estrogen receptor alpha (ERα, encoded by ESR1) is a ligand-activated transcription factor with pivotal roles in mammalian sexual development, reproductive function, bone metabolism, and cellular homeostasis—while also standing as a critical diagnostic and prognostic biomarker for estrogen receptor-positive (ER+) breast cancer, endometrial cancer, and other hormone-driven malignancies. The study of ERα’s functional regulation, particularly its post-translational modification at key residues like Y537, demands highly specific antibodies that can distinguish distinct molecular forms of the receptor and perform reliably across diverse experimental assays. Yet many commercial ERα antibodies suffer from critical limitations: cross-reactivity with ERβ, inability to discriminate phosphorylation states of Y537, narrow species reactivity, or poor performance in formalin-fixed paraffin-embedded (FFPE) tissue analysis. The Abbkine ERα Polyclonal Antibody (Cat. No. ABP0086) (product…
Abbkine Actin Polyclonal Antibody (ABP0056): A Universal Gold-Standard Tool for Actin Detection Across Biological Research

Abbkine Human MYC-Induced Nuclear Antigen (MINA) ELISA Kit (KTE61613): A Precision Practical Guide for Quantitative MINA Detection in MYC-Driven Biology and Disease Research
MYC-induced nuclear antigen (MINA, also known as MINA53/MDIG) is a critical downstream target of the c-MYC oncoprotein, serving as a key mediator of c-MYC-driven cell proliferation, growth regulation, and pathological progression in MYC-amplified cancers—while also playing a role in mineral dust-induced cellular stress and lung injury. As a nuclear-localized protein, MINA’s soluble fragments in biological fluids exist at low endogenous abundance, and the structural homology among c-MYC target gene products creates inherent risks of cross-reactivity in non-specific detection assays.

This two-site sandwich ELISA kit is optimized exclusively for human MINA quantification, boasting high sensitivity,…
Abbkine Human Malectin (MLEC) ELISA Kit (KTE61601): A Precision Tool for ER Homeostasis and Glycosylation Research
Malectin (MLEC) stands as a cornerstone ER-resident carbohydrate-binding protein, orchestrating critical cellular processes including N-glycosylation regulation, misfolded protein degradation, and endoplasmic reticulum (ER) homeostasis maintenance.

Abbkine Human Matrix Metalloproteinase 14 (MMP-14) ELISA Kit (KTE61598): A Game-Changer for MMP-14 Quantification in ECM Remodeling and Cancer Research
Matrix Metalloproteinase 14 (MMP-14), also known as MT1-MMP, isn’t just another member of the MMP family—it’s the membrane-anchored workhorse of extracellular matrix (ECM) remodeling, a key activator of pro-MMP2, and a critical driver of tumor invasion, tissue development, and pathological processes like arthritis. For researchers digging into MMP-14’s role in health and disease, accurate quantitative detection of this protein has long been a struggle: the high structural homology across MMP family members causes cross-reactivity in generic assays, membrane-bound MMP-14 is hard to isolate without harsh lysis, and soluble MMP-14 fragments (the form found in biological fluids) are often present at low, hard-to-detect levels. The Abbkine Human Matrix Metalloproteinase 14 (MMP-14) ELISA Kit (Cat. No. KTE61598) (product link: https://www.abbkine.com/product/human-matrix-metalloproteinase-14-mmp-14-elisa-kit-kte61598/) changes all that. This two-site…
Abbkine Human Myeloperoxidase (MPO) ELISA Kit (KTE61560): A Comprehensive Practical Guide for Quantitative MPO Detection
Myeloperoxidase (MPO) is a core heme-containing enzyme of neutrophil azurophilic granules, serving as a key mediator of innate immune microbicidal activity and a critical biomarker for inflammatory, infectious, and autoimmune disorders. Its accurate quantitative detection is indispensable for research spanning immunology, inflammation biology, and clinical translational science—yet the field faces persistent technical pitfalls: MPO’s inherent enzymatic lability leading to rapid sample degradation, non-specific cross-reactivity in generic detection assays, and poor standard curve linearity in low-abundance MPO quantification. The Abbkine Human Myeloperoxidase (MPO) ELISA Kit (Cat. No. KTE61560) (product link: https://www.abbkine.com/product/human-myeloperoxidase-mpo-elisa-kit-kte61560/) addresses these challenges as a purpose-engineered two-site sandwich ELISA kit, boasting high sensitivity, excellent human MPO specificity (no cross-reactivity with analogues), and a validated standard curve with R²=0.9921—the gold standard for quantitative ELISA…
Abbkine Human MAGUK p55 Subfamily Member 7 (MPP7) ELISA Kit (KTE61556): A Precision Practical Guide for Quantitative MPP7 Detection in Epithelial and Skeletal Biology Research
Membrane palmitoylated protein 7 (MPP7), a key member of the MAGUK p55 Stardust family, is a non-negotiable molecular player in orchestrating epithelial cell polarity, tight junction biogenesis and site-specific bone mineral density regulation—making its accurate quantitative detection a foundational step for research spanning cell biology, skeletal physiology and tissue repair. As a membrane-associated guanylate kinase (MAGUK) protein, MPP7 exists primarily as a palmitoylated membrane-bound form with low-abundance soluble fragments in biological fluids and cell culture supernatants; compounding this challenge, the high structural homology among MAGUK family members creates a risk of cross-reactivity in non-optimized detection assays. For researchers seeking reliable, specific quantification of human MPP7, the Abbkine Human MAGUK p55 subfamily member 7 (MPP7) ELISA Kit (Cat. No. KTE61556) (product link: https://www.abbkine.com/product/human-maguk-p55-subfamily-member-7-mpp7-elisa-kit-kte61556/) emerges…
Abbkine Collagen I Mouse Monoclonal Antibody (4H10) (ABM40379): A Gold-Standard Tool for Type I Collagen Research Across Biological Disciplines
Type I Collagen, encoded by the COL1A1 gene, is the most abundant fibril-forming collagen in the human body and the structural backbone of nearly all connective tissues, including bone, dermis, tendon, and cornea. Its biological significance extends far beyond structural support: mutations in COL1A1 are linked to a spectrum of heritable connective tissue disorders such as osteogenesis imperfecta, Ehlers-Danlos syndrome, and idiopathic osteoporosis, while its dysregulated deposition and remodeling drive pathological processes in cancer stroma formation, tissue fibrosis, and chronic wound healing. For researchers in skeletal biology, tumor microenvironment (TME) research, regenerative medicine, and clinical pathology, the specific and sensitive detection of endogenous Type I Collagen is an indispensable experimental step—yet the field has long struggled with key technical challenges,…
