A-Z> All Other Proteins > Siglec-2 > Human Siglec-2 / CD22 Protein, Llama IgG2b Fc Tag, low endotoxin 
This protein carries a llama IgG2b Fc tag at the C-terminus.
The protein has a calculated MW of 103.0 kDa. The protein migrates as 120-140 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.
