MIP-3 alpha, BioAssay(TM) ELISA Kit (Mouse) (CCL20, Macrophage Inflammatory Protein 3 alpha, C-C Mot

Macrophage Inflammatory Protein 3 alpha (MIP3alpha), also called Chemokine, cc motif, ligand 20(CCL20). The MIP-3alpha/CCL20 gene was cloned and sequenced, revealing a four exon, three intron structure, and was localized by FISH analysis to 2q35-q36. MIP3alpha is predominantly expressed in lymph nodes, appendix, PBL, fetal liver, fetal lung and several cell lines. MIP3alpha/CCL20 and its receptor CCR6 are markedly up-regulated in psoriasis, and they may play a role in the recruitment of T cells to lesional psoriatic skin. And Alanine MIP-3alpha and Serine MIP-3alpha, the two forms of MIP3alpha, that differ by one amino acid at the predicted signal peptide cleavage site. Both of them were chemically synthesized and tested for biological activity. And both flu antigen plus IL-2-activated CD4(+) and CD8(+) T lymphoblasts and cord blood-derived dendritic cells responded to Ser and Ala MIP-3alpha. Sample Type: Cell culture supernates, serum and plasma (heparin, EDTA), Intended Use: For quantitative detection of mouse CCL20 in cell culture supernates, serum and plasma (heparin, EDTA). Sensitivity: <1pg/ml, Range: 7.8-500pg/ml, Specificity: Natural and recombinant mouse CCL20 , Test Principle: This mouse CCL20 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for CCL20 has been precoated onto 96-well plates. Standards(E.coli) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for CCL20 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 mouse CCL20 amount of sample captured in plate.
