Application: For quantitative detection of B7-1 in mouse serum,tissue lysates or cell culture supernatants.
Introduction: Cluster of Differentiation 80 (also CD80 and B7-1) is a protein found on activated B cells and monocytes. B7-1 provides regulatory signals for T lymphocytes as a consequence of binding to the CD28 and CTLA4 ligands of T cells. The CD80 gene has 6 exons that span approximately 32 kb of genomic DNA. The antigen presentation coactivators B7-1 and B7-2 may be important for lymphocytic infiltration and the immune response against thyroid carcinoma.
Principle of the Assay: This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-B7-1 polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-B7-1 polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were 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 B7-1 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of B7-1 can be calculated.
Storage and Expiration: Store at 2-8℃ for 6 months, or at -20℃ for 12 months.
Range: 62.5 pg/ml - 4000 pg/ml
Sensitivity: < 10 pg/ml
