Product Name: TGFB1 Human

Product No: CYT-561

Synonym(s): Transforming Growth Factor-beta 1 Human, Transforming growth factor beta-1, TGF-beta-1, CED, DPD1, TGFB, TGF-b 1.

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 Derived From: Human Platelets.

Physical Appearance: Sterile Filtered lyophilized powder.

Purity: Greater than 98.0% as determined by SDS-PAGE.

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.

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.
