Properties
| Form | Powder |
|---|---|
| Purification Note | Endotoxin level is <0.1 EU/µg of the protein, as determined by the LAL test. |
| Purity | >98% (by SDS-PAGE) |
| Buffer | PBS (pH 8.0) |
| Reconstitution | It is recommended to reconstitute the lyophilized protein in sterile water to a concentration not <200 μg/mL and incubate the stock solution for at least 20 min at room temperature to make sure the protein is dissolved completely. |
| Storage Instruction | For long term, lyophilized protein should be stored at -20°C or -80°C. After reconstitution, aliquot and store at -20°C or -80°C for up to one month. Storage in frost free freezers is not recommended. Avoid repeated freeze/thaw cycles. Suggest spin the vial prior to opening. |
| Note | For laboratory research only, not for drug, diagnostic or other use. |
Bioinformation
| Gene Symbol | TGFA |
|---|---|
| Gene Full Name | transforming growth factor, alpha |
| Background | This gene encodes a growth factor that is a ligand for the epidermal growth factor receptor, which activates a signaling pathway for cell proliferation, differentiation and development. This protein may act as either a transmembrane-bound ligand or a soluble ligand. This gene has been associated with many types of cancers, and it may also be involved in some cases of cleft lip/palate. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011] |
| Function | TGF alpha is a mitogenic polypeptide that is able to bind to the EGF receptor/EGFR and to act synergistically with TGF beta to promote anchorage-independent cell proliferation in soft agar. [UniProt] |
| Cellular Localization | Transforming growth factor alpha: Secreted, extracellular space. Protransforming growth factor alpha: Cell membrane; Single-pass type I membrane protein. [UniProt] |
