|
| Purity |
> 95% as determined by BisTris PAGE
> 95% as determined by HPLC |
| Endotoxin Level |
Less than 1EU per μg by the LAL method. |
| Biological Activity |
Fc gamma RIIB, His, Cynomolgus captured on CM5 Chip via AntiHis Antibody can bind Trastuzumab in SPR assay (Biacore T200). Test result was comparable to standard batch. |
| Expression System |
HEK293 |
| Theoretical Molecular Weight |
21 kDa |
| Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 33-40 kDa based on Bis-Tris PAGE result. |
| Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). |
| Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
| Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
| Target Background |
The Fc gamma Rs have been divided into three classes based on close relationships in their extracellular domains; these groups are designated Fc gamma RI (also known as CD64), Fc gamma RII (CD32), and Fc gamma RIII (CD16). Each group may be encoded by multiple genes and exist in different isoforms depending on species and cell type. The CD64 proteins are high affinity receptors (~10e-8-10e-9 M) capable of binding monomeric IgG, whereas the CD16 and CD32 proteins bind IgG with lower affinities (~10e-6-10e-7 M) only recognizing IgG aggregates surrounding multivalent antigens. |
