85-4740-16　Ctsb, Recombinant, Mouse, aa18-339, His-Tag (Cathepsin B Preproprotein, CB) 10ug　377778

特徴

• CTSB, also known as cathepsin B preproprotein, is a papain-family cysteine protease that is normally located in lysosomes. It has the ability to degrade several extracellular matrix components at both neutral and acidic pH and has been implicated in the progression of several human and rodent tumors progression and arthritis.
• Source:Recombinant protein corresponding to aa18-339 from mouse CTSB, fused to His-Tag at C-terminal, expressed in insect cell.
• Molecular Weight:~36.4kD (330aa), 28-40kD (SDS-PAGE under reducing conditions)
• Endotoxin:<1EU/1ug (determined by LAL method)
