| Form : |
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization. |
| Bio-activity : |
Biotinylated Feline FCGRT&B2M Heterodimer Protein, His,Avitag captured on Biotin CAP-Series S Sensor Chip can bind Herceptin with an affinity constant of 1.19 nM as determined in a SPR assay (Biacore T200). |
| Molecular Mass : |
Biotinylated Feline FCGRT&B2M Heterodimer Protein, His,Avitag, produced by co-expression of FCGRT and B2M, has a calculated MW of 34.0 kDa (FCGRT) and 11.5 kDa (B2M). Subunit FCGRT is fused with a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™) and subunit Beta-2 microglobulin (B2M) contains no tag. The reducing (R) protein migrates as 36-40 kDa (FCGRT) and 18-20 kDa (B2M) respectively due to glycosylation. |

| Storage : |
For long term, the product should be stored at lyophilized state at -20°C or lower.Please protect from light and avoid repeated freeze-thaw cycles.This product is stable after at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution. |
| Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents. |
