Description
This Human Chemokine Ligand 2 (CCL2) ELISA Kit is intended for quantitative detection of human MCP-1 in cell culture supernates, serum, plasma (heparin, EDTA, citrate) and urine. Strip well format. Reagents for up to 96 tests.
This human MCP-1 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A polyclonal antibody from goat specific for MCP-1 has been precoated onto 96-well plates. Standards (E Coli, 24-T99) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for MCP-1 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human MCP-1 amount of sample captured in plate.
The capture antibody is a polyclonal antibody from goat, the detection antibody is a biotinylated polyclonal antibody from goat. Expression system for standard: Monocyte chemoattractant protein-1 (MCP-1), a member of the chemokine (chemotactic cytokine) family, is a potent monocyte agonist that is upregulated by oxidized lipids. MCP-1 is also known as CCL2, SCYA2, MCAF. MCAF is a member of family of factors involved in immune and inflammatory responses. The amino acid sequence deduced from the nucleotide sequence reveals the primary structure of the MCAF precursor to be composed of a putative signal peptide sequence of 23 amino acid residues and a mature MCAF sequence of 76 amino acid residues. MCP-1 plays a unique and crucial role in the initiation of atherosclerosis and may provide a new therapeutic target in this disorder. Human MCP-1 is a 8.7KDa non-glycoprotein, consisting of 99 amino acids in precursor form and 76 amino acids in mature form
