Source:
The recombinant Human ICOS/CD278 (C136S, C137S) Protein, (amino acids Glu21-Phe141(C136S,C137S)) fused with a His tag at the C-terminus, was produced in HEK 293 cells.
Molecular Weight :
The recombinant Human ICOS/CD278 (C136S, C137S) protein with the His tag at the C-terminus has a predicted MW of 14.8 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Tris-Bis PAGE result.
