| Species | Human | ||||||
| Protein Construction |
|
||||||
| Conjugate | Biotin | ||||||
| Purity | > 95% as determined by BisTris PAGE | ||||||
| Endotoxin Level | Less than 1EU per μg by the LAL method. | ||||||
| Biological Activity | Measured by its binding ability in a functional ELISA.Test result was comparable to standard batch. | ||||||
| Expression System | HEK293 | ||||||
| Theoretical Molecular Weight | 21.04 kDa | ||||||
| Apparent Molecular Weight | Due to glycosylation, the protein migrates to 40-60 kDa based on Bis-Tris PAGE result. | ||||||
| Formulation | Lyophilized from 0.22 μm 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 for 6 months at -20℃ or below. Upon reconstitution, the product should be stable for 3 months at -80℃. Avoid repeated freeze-thaw cycles. |
| Target Background | B7-H5, also known as VISTA , B7H5, Dies1, SISP1 and C10orf54, is a 55-65 kDa member of the Ig superfamily. It is a transmembrane molecule expressed in bone, on embryonic stem cells (ESCs), and on tumor cell surfaces. |
| Synonyms | B7H5; B7-H5; VISTA; VSIR ; PD1H; PD-1H; 4632428N05Rik; C10orf54; Dies1; Gi24; PP2135; SISP1 |
产品特点：
