Recombinant Biotinylated Human Fc gamma RIIIB/CD16b (NA2) Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal.It contains Gly17-Ser200(NA2). The CD16b NA1 differ with the CD16b NA2 in AA36, 65, 82, and 106. The CD16b NA1form carries R36, N65, D82, and V106, while the CD16b NA2 form carries S36, S65, N82, and I106.
The protein has a predicted MW of 23.7 kDa. Due to glycosylation, the protein migrates to 47-53 kDa based on Tris-Bis PAGE result.
