Mouse Cathepsin B, His Tag (CTB-M52H9) is expressed from human 293 cells (HEK293). It contains AA His 18 - Phe 339 (Accession # P10605-1).
Predicted N-terminus: His 18
Request for sequence蛋白结构(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus. This protein contains an Activation peptide, and will be partially processed into Pro form with calculated MW of 37.3 kDa and mature form with calculated MW of 29 kDa under reducing (R) condition. The protein migrates as 43-47 kDa and 32-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
