This protein carries a polyhistidine tag at the C-terminus.
The Human Cathepsin B will be further processed into mature form (Leu 80-Ile 339). The protein has a calculated MW of 36.7 kDa (pro-form) and 29.5 kDa (mature-form). The protein migrates as 42-50 kDa and 34 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH8.0 with trehalose as protectant.
