Human CD79A&CD79B Heterodimer Protein, Mouse IgG2a Fc,Flag Tag&Mouse IgG2a Fc,His Tag is produced by co-expression of CD79A and CD79B, has a calculated MW of 43.8 kDa (CD79A) and 46.7 kDa (CD79B). Subunit CD79A carries a mouse IgG2a Fc fragment at the C-terminus, followed by a flag tag and subunit CD79B carries a mouse IgG2a Fc fragment at the C-terminus, followed by a polyhistidine tag. The non-reducing (NR) protein migrates as 115-120 kDa due to glycosylation.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
