产品名称：大鼠TNFαELISA试剂盒
货号：EK0526
Tumor necrosis factor α (TNFα or TNF) is secreted by macrophages in response to inflammation, infection, and cancer. Rat Tumor Necrosis Factor (TNF) and Lymphotoxin (TNFβ) are cytotoxic proteins which have similar biological activities and share 30% amino acid homology. TNFα is produced by monocytes, which can stimulate endothelial cells to produce the multi-lineage growth factor granulocyte-macrophage colony-stimulating factor (GM-CSF) and extend the role of this immunoregulatory protein to the regulation of hematopoiesis in vitro. TNF is a soluble protein that causes damage to tumor cells, but has no effect on normal cells. Rat TNF has been purified to apparent homogeneity as a 17.3kDa protein from HL-60 leukemia cells and has shown cytotoxic and cytostatic activities against various rat tumor cell lines. The Rat TNF cDNA is 1585 base pairs in length and encodes a protein of 233 amino acids. The mature protein begins at residue 77, leaving a long leader sequence of 76 amino acids. TNFα has been mapped to human chromosome 6. The standard product used in this kit is recombinant rat TNFα, consisting of 157 amino acids with a molecular mass of 17kDa. ScienCell's rat TNFα ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. Rat TNFα-specific monoclonal antibodies are pre-coated onto 8 x 12 strips. The rat-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 rat TNFα 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。
