人双调蛋白酶联免疫试剂盒描述：

       Angiogenin (Ang), also known as ribonuclease 5, is a protein that in humans is encoded by the ANG gene. Angiogenin is a potent stimulator of new blood vessel formation. It hydrolyzes cellular tRNAs resulting in decreased protein synthesis, and it is similar to pancreatic ribonuclease. Hooper et al. (2003) reviewed the evidence that angiogenins are involved in host defense and noted that inflammation provokes upregulated ANG mRNA expression in liver and an increase in detectable ANG protein in serum. Weremowicz et al. (1989, 1990) assigned the human angiogenin gene to chromosome 14q11.

       ScienCell's human ANG ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. Human ANG specific-specific polyclonal antibodies are precoated onto 8 x 12 divisible strips. The human 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 into yellow after adding acidic stop solution. The intensity of yellow is proportional to the amount of human ANG that is captured in the strips.
