Recombinant Human SIRP alpha V2/CD172a Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Glu31-Arg369.
Molecular Weight:
The protein has a predicted MW of 38 kDa. Due to glycosylation, the protein migrates to 55-65 kDa based on Bis-Tris PAGE result.
Tag:
C-His
UniProt:
AAH26692.1
Buffer:
Lyophilized from 0.22µm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Expression System:
HEK293
Purity:
> 95% as determined by Bis-Tris PAGE,> 95% as determined by HPLC
Form:
Lyophilized
Sequence:
Glu31-Arg369
