SerpinB1 Antibody (4D7) is a mouse monoclonal IgG2b kappa light chain antibody that detects SerpinB1 protein of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). Anti-SerpinB1 antibody (4D7) is available as a non-conjugated format. SerpinB1, also known as monocyte/neutrophil elastase inhibitor (M/NEI) or leukocyte elastase inhibitor (LEI), plays a crucial role in regulating the activity of neutrophil elastase, cathepsin G, and proteinase-3, which are important for maintaining homeostasis in inflammatory responses. By inhibiting these serine proteases, SerpinB1 helps to control tissue damage during inflammation and prevents excessive proteolytic activity that can lead to chronic inflammatory diseases. Located primarily in the cytoplasm, SerpinB1′s ability to quickly inhibit proteases is vital for protecting tissues from damage during immune responses. Additionally, the gene encoding SerpinB1, SERPINB1, is part of the Ov-serpin family and has four homologous genes in mice, with SerpinB1a being the functional ortholog of the human counterpart. The presence of SerpinB1 is essential for proper immune function, and dysregulation has been implicated in various pathological conditions, making SerpinB1 a significant target for research and therapeutic interventions.

请问推荐做IP的稀释比是多少?

Asked by: bobo11
Thanks for your question. 1 ml of cell lysate, or approximately 100–1000 µg of total cellular protein with 1–10 µl (i.e., 0.2–2 µg) primary antibody (optimal antibody concentration should be determined by titration) . 谢谢您的问题。1 ml细胞裂解液,或约100-1000µg细胞总蛋白,加入1 - 10µl(即0.2-2µg)一抗(最佳抗体浓度应通过滴定确定)。
