Transforming Growth Factor-beta 1 Human ( TGF b 1 Human )
DescriptionHuman Transforming Growth Factor-beta 1 purified from Human Platelets having a molecular mass of 25kDa.The TGF-b 1 is purified by proprietary chromatographic techniques.SourceHuman Platelets.Physical AppearanceSterile Filtered lyophilized
Data sheet
| Formulation | TGF-Beta1 protein was lyophilized from a solution containing 30% acetonitrile and 0.1% trifluoroacetic acid. |
| Solubility | It is recommended to reconstitute lyophilized TGF-beta 1 in 0.5% BSA in 0.1N acetic acid, which can then be further diluted to the desired aliquot with 30% acetonitrile and 0.1% trifluoroacetic acid. |
| Purity | Greater than 98.0% as determined by SDS-PAGE. |
| Description | Human Transforming Growth Factor-beta 1 purified from Human Platelets having a molecular mass of 25kDa.The TGF-b 1 is purified by proprietary chromatographic techniques. |
| Protein Background | Transforming growth factor betas (TGF Betas) mediate many cell-cell interactions that occur during embryonic development. Three TGFBetas have been identified in mammals. TGFBeta1, TGFBeta2 and TGFBeta3 are each synthesized as precursor proteins that are very similar in that each is cleaved to yield a 112 amino acid polypeptide that remains associated with the latent portion of the molecule. |
| Expression host | Human Platelets. |
| Synonyms | Transforming growth factor beta-1, TGF-beta-1, CED, DPD1, TGFB, TGF-b 1. |
| Reagent Appearance | Sterile Filtered lyophilized powder. |
| Stability | Lyophilized TGF-beta 1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TGF-beta 1 should be stored at 4°C between 2-7 days and for future use below -18°C.DO NOT RECONSTITE WITH NEUTRAL BUFFERS.DO NOT USE GLASS IMPLEMENTS OR EXTENSIVE MANIPULATIONS.PREVENT FREEZE THAW CYCLES. |
| Biological Activity | Stimulates the growth of NRK-1 cells in soft agar at concentrations ranging from 0.1 to 5ng/ml corresponding to a specific activity of 200,000-10,000,000IU/mg. Effective concentration ranges must be experimentally determined. Purified EGF and/or TGF- must be present for observation of the biological activity. |
