Human TGFB1 Protein

• Catalog Number: orb429487
• Category: Proteins
• Description: Human TGF beta 1 protein
• Form/Appearance: Sterile Filtered lyophilized powder.
• Purity: Greater than 98.0% as determined by SDS-PAGE.
• Solubility (25°C): 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.
• Source: Human Platelets
• 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.
• Storage: 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
• Buffer/Preservatives: TGF-Beta1 protein was lyophilized from a solution containing 30% acetonitrile and 0.1% trifluoroacetic acid.
