Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization. |
| Bio-activity : |
Loaded Cynomolgus / Rhesus macaque FCGRT&B2M Heterodimer Protein, His Tag&Strep II Tag on SA Biosensor via Biotin his antibody, can bind Herceptin with an affinity constant of 0.13 μM as determined in BLI assay (ForteBio Octet Red96e).Loaded Biotinylated Cynomolgus Serum Albumin, His,Avitag on SA Biosensor, can bind Cynomolgus / Rhesus macaque FCGRT&B2M Heterodimer Protein, His Tag&Strep II Tag with an affinity constant of 0.684 μM as determined in BLI assay (ForteBio Octet Red96e). |
| Molecular Mass : |
Cynomolgus / Rhesus macaque FCGRT&B2M Heterodimer Protein, His Tag&Strep II Tag, produced by co-expression of FCGRT and B2M, has a calculated MW of 32.3 kDa (FCGRT) and 13.1 kDa (B2M). Subunit FCGRT is fused with a polyhistidine tag at the C-terminus and subunit Beta-2 microglobulin (B2M) is fused with Strep II-tag at the C-terminus. The reducing (R) protein migrates as 36 kDa (FCGRT) and 14 kDa (B2M) respectively due to glycosylation. |
