This protein carries a polyhistidine tag at the N-terminus. The protein migrates as 50-60 kDa on a SDS-PAGE gel under reducing (R) condition. This protein can bind to VL-Kappa.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
