Mouse Serpin A11 HEK293 Overexpression Lysate: Product Information
This Mouse Serpin A11 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of Serpin A11 protein (Cat: 50435-M08H) from the overexpression lysate was verified.
A DNA sequence encoding the mouse SERPINA11 isoform 1 (NP_955018.2) (Met 1-Gly 424) was expressed, fused with a polyhistidine tag at the C-terminus.
The secreted recombinant mouse SERPINA11 comprises 414 amino acids and has a predicted molecular mass of 46.2 kDa. As a result of glycosylation, the apparent molecular mass of rm SERPINA11 is approximately 60-65 kDa in SDS-PAGE under reducing conditions.
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Serpins are the largest and most diverse family of serine protease inhibitors which are involved in a number of fundamental biological processes such as blood coagulation, complement activation, fibrinolysis, angiogenesis, inflammation and tumor suppression and are expressed in a cell-specific manner. Serpins are a group of proteins with similar structures that were first identified as a set of proteins able to inhibit proteases. The acronym serpin was originally coined because many serpins inhibit chymotrypsin-like serine proteases (serine protease inhibitors). Over 1 serpins have been identified. Mouse Serpin A11, also known as SERPINA11, is a member of the serpin family.
