This protein carries a polyhistidine tag at the C-terminus. This protein undergoes autocatalytic cleavage to release the pro-peptide and mature chain. The pro-peptide and mature chain are associated through non‑covalent interactions and with a calculated MW of 13.9 kDa and 59.3 kDa respectively. The protein migrates as 17 kDa and 65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
