Human CD28 / TP44 Protein (Fc & AVI Tag), Biotinylated 11524-H41H-B from Sino Biological, Inc.

Description

A DNA sequence encoding the human CD28 (NP_006130.1) (Met1-Pro152) was expressed with a C-terminal Fc region of human IgG1 tag followed by an AVI tag. The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. Human, Cynomolgus and Rhesus CD28 sequences (Asn19-Pro152) are identical
