>Human / Cynomolgus / Rhesus macaque CD28 Protein, Fc Tag
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 41.6 kDa. The protein migrates as 55-66 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, 25 mM Arg, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
