Description

The protein CD80 (Cluster of Differentiation 80), also known as B7-1, is a moleculeFound on activated B cells and monocytes. CD80 provides a co-stimulatory signal necessaryFor T cell activation and survival. The cDNAFor CD80/B7-1 predicts it to be a type I membrane protein, i.e., one synthesized with a signal peptide that is cleaved upon translocation across the endoplasmic membrane. The protein is predicted to contain two extracellular domains structurally similar to those of immunoglobulin (Ig), a hydrophobic transmembrane region, and a short cytoplasmic domain. The CD80 and CD86 (601020) genes encode B7-1 and B7-2, respectively, which are structurally similar members of the immunoglobulin superfamily expressed on a variety of hematopoietic cell types. It is known that B7-1 and B7-2 provide a co-stimulatory signal to T cells by interacting with CD28 and CTLA4. The standard product used in this kit is recombinant B7-1,D37-K245,which is composed of two single chains acids with the dipolymer.

ScienCells mouse B7-1/CD80 ELISA kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. Mouse B7-1/CD80-specific polyclonal antibodies are pre-coated onto 8 x 12 divisible strips. The mouse-specific detection polyclonal antibodies are biotinylated. The test samples and biotinylated detection antibodies are subsequently added to the wells and then washed with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes to yellow after adding acidic stop solution. The intensity of yellow is proportional to the amount of mouse B7-1/CD80 in the sample that is captured on the strips.

 Sciencell公司产品由上海中乔新舟生物科技有限公司优质供应 

       近几年的新药研发成功率在逐年下降，其根本原因之一就是传统的药物筛选系统是建立在只具有30-40%人类基因群的一系列细胞株上。这样一个有“缺陷型”药物筛选系统所产生的药物用于人体上就会出现许多致命的弱点和不完整性。新一代药物筛选系统是含有一系列近乎完整的人类基因群的原代细胞株。而利用这些原代细胞株所甄别和筛选出来的候选药物，其诊治人类疾病的成功几率将大大增加。这样不但大大节省了新药的开发成本，而且将极大地提高人类的健康质量。这些产品从根本上提高了全球生命医学研究、人类重要疾病药物研发、新药研发的成功率。所以上海中乔新舟生物科技有限公司致力于提供优质原代细胞产品和完善的售后服务。
