TGF b 3 HumanTransforming Growth Factor-Beta 3 Human Recombinant 重组人转化生长因子-β3Catalog No. CYT-368Synonyms:Transforming Growth Factor-beta3, TGFB3, ARVD, FLJ16571, TGF-beta3.Introduction:Transforming growth factor betas (TGF Betas) mediate many cell-cell interactions that occur during embryonic development. Three TGF Betas have been identified in mammals. TGF Beta 1, TGF Beta 2 and TGF Beta 3 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. Description:TGF-b3 Human Recombinant produced in E.Coli is a disulfide-linked homodimeric, non-glycosylated, polypeptide chain containing 112 amino acids and having a molecular mass of 25,445 Dalton. The TGF-b 3 is purified by standard chromatographic techniques.Source:Escherichia Coli. Physical Appearance:Sterile Filtered clear solution.Formulation:The protein solution contains 20% Ethanol and 0.12% Acetic acid.Stability:TGF-beta 3 although stable at room temperature for 3 weeks, should be stored at 4°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Purity:Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. Amino acid sequence:The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Leu-Asp-Thr-Asn.Biological Activity:The as determined by the cell toxicity assay using the WHO Standard 98/608 as a direct comparison is < 0.05ng/ml.Protein content:Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm using the absorbency value of 1.718 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of TGF-b 3 as a Reference Standard. Usage:Prospec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.相关产品：TGF-b1 重组人转化生长因子-β1 CYT-473 Recombinant Human Transforming Growth Factor-Beta 1TGF-b1 人转化生长因子-β1 CYT-561 Human Transforming Growth Factor-Beta 1TGF-b1 His 重组人转化生长因子-β1 His CYT-672 Recombinant Human Transforming Growth Factor-Beta 1 His TagTGF-b3 重组人转化生长因子-β3 CYT-368 Recombinant Human Transforming Growth Factor-Beta 3TGF-b3 (207 a.a.) 重组人转化生长因子-β3(207 a.a.) CYT-319 Recombinant Human Transforming Growth Factor-Beta 3 (644-850)TGF-b1 (113 a.a.)  重组人转化生长因子-β1(113 a.a.) CYT-679 Recombinant  Human Transforming Growth Factor-Beta 1 (113 a.a.)
