This Mouse CHODL overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of CHODL protein (Cat: 50699-M08H) from the overexpression lysate was verified.
A DNA sequence encoding the extracellular domain of mouse CHODL (EDK98299.1) (Met 1-Asn 216) was expressed, fused with a polyhistidine tag at the C-terminus.
The recombinant mouse CHODL comprises 206 amino acids and has a calculated molecular mass of 23.4 kDa. As a result of glycosylation, the apparent molecular mass of rnCHODL is approximately 34 kDa in SDS-PAGE under reducing conditions.
Mouse CHODL HEK293 Overexpression Lysate: 使用指南
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.
