Description

Interleukin-1-a (IL-1a) and interleukin-1-β (IL-1β) are two biochemically distinct, but distantly related, polypeptidic cytokines that play a key role in inflammation, immunologic reactions, and tissue repair. IL-1a has been implicated in the pathogenesis of infectious, autoimmune and inflammatory diseases. Recently, it has been shown that IL-1a is identical to hematopoietin 1, which is described as a hematopoietic growth factor acting on early progenitor cells in synergy with other hematopoietic growth factors. The human interleukin 1a gene is assigned to chromosome 2. Genetic polymorphisms at IL-1a and IL-1β have been recently suggested to be associated with severity of adult periodontitis. The murine IL-1a and IL-1β genes encode structurally and evolutionarily related cytokines that exert a regulatory role in numerous physiological processes including hemopoiesis. The standard product used in this kit is recombinant human IL-1a with the molecular mass of 18kDa.

ScienCells human IL-1a ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. Human IL-1a-specific monoclonal antibodies are pre-coated onto 8 x 12 divisible strips. The human specific detection monoclonal 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 into yellow after adding acidic stop solution. The intensity of yellow is proportional to the amount of human IL-1a captured in strips.

       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。
