Cat#: | RP-6065H |
Product Name: | Recombinant Human TGF b 1 Protein Recombinant |
Synonym: | Transforming growth factor beta-1, TGF-beta-1, CED, DPD1, TGFB, TGF-b 1, LAP, TGFB1. |
Description: | TGFB1 Protein produced in Human 293 cells is a glycosylated homodimeric polypeptide chain containing 2 x 112 amino acids and having a total molecular mass of 25.6kDa. The TGFB1 is purified by proprietary chromatographic techniques. |
Source: | Human 293 cells. |
AA Sequence: | ALDTNYCFSS TEKNCCVRQL YIDFRKDLGW KWIHEPKGYH ANFCLGPCPY IWSLDTQYSK VLALYNQHNP GASAAPCCVP QALEPLPIVY YVGRKPKVEQ LSNMIVRSCK CS. |
Purity: | Greater than 95.0% as determined by SDS-PAGE. |
Bioactivity: | The ED50 as determined by the dose-dependent inhibition of IL-4-induced proliferation of mouse HT-2 cells is less than 0.05ng/ml, corresponding to a specific activity of 2x107units/mg. |
Formulation: | Lyophilized from a sterile filtered solution containing 50mM Glycine, 50mM sodium chloride, 10% Trehalose and BSA (4:1 protein to BSA ratio) pH 4.0. |
Stability: | Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃ |
Reconstitution: | It is recommended to reconstitute the lyophilized TGFB1 in sterile 10mM Acetic Acid at a concentration of 0.1 mg/ml, which can then be further diluted to other aqueous solutions. |
Storage: | Lyophilized TGFB1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TGFB1 Human should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
