Product Description
Specifications
| Size | 50 µg, 100 µg |
| Species | Human |
| Accession Number | P0DN86 |
| Gene Symbols | CGB3 |
| Protein Name / Synonyms | HCG-beta, Choriogonadotropin subunit beta 3, Chorionic gonadotropin chain beta |
| Expressed Region | Ser21-165 |
| Expression System | HEK293 cells |
| Tag | N-terminal histidine tag |
| Purity | >95% |
| Purity Determined By | SDS-PAGE under reducing conditions and visualized by Coomassie blue staining |
| Molecular Weight (kDa) | Recombinant protein product has a calculated molecular mass of 16 kDa. Due to the abundant glycosylation, it migrates as approximately 30 kDa protein band in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions. See deglycosylation analysis image below. |
| Format | Lyophilized powder |
| Formulation | Lyophilized from a 0.2 µm filtered solution in PBS (pH 7.4) with 1% mannitol and 5% trehalose |
| Concentration (lot specific) | Determined by Pierce BCA protein assay |
| Reconstitution | Briefly spin the vial and bring the contents to the bottom prior to opening. It is recommended to reconstitute at 0.5 - 1.0 mg/mL with sterile deionized water. |
| Endotoxin Level | <0.5 EU per µg of the protein as determined by the LAL method |
| Recombinant or Native | Recombinant |
| Shipping Type | Ambient temperature |
| Storage | -20°C |
| Storage / Stability | Upon arrival, the lyophilized protein may be stored for 2 weeks at 4°C. For long term storage, it is recommended to store desiccated below -20 °C in a manual defrost freezer. Following reconstitution, the protein may be stored for 2 weeks under sterile conditions at -20 °C. For long term storage, it is recommended to make appropriate aliquots and store at -80 °C. Avoid repeated freeze-thaw cycles. |
