|Product name||Recombinant Human TGF-beta 1 Protein|
|Description||Recombinant Human TGF-beta 1 Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Leu30-Ser390(C33S)) of human TGF-beta 1 (Accession #NP_000651.3) fused with an 8×His tag at the N-terminus.|
|Bio-Activity||Measured by its ability to inhibit cell proliferation of TF-1 human erythroleukemic cells. The ED50 for this effect is typically 0.5-2 ng/mL.|Measured by its binding ability in a functional ELISA. Immobilized recombinant human TGFB1 at 2 ug/mL (100 µL/well) can bind recombinant human TGFBR2 with a linear range of 1-5 ng/mL.|
|Purity||> 95% by SDS-PAGE.|
|Endotoxin||< 0.1 EU/μg of the protein by LAL method.|
|Formulation||Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.|
|Synonym||CED; DPD1; LAP; TGF-beta 1; TGFB; TGFbeta|
|Expressed Host||HEK293 cells|
|Storage||Store the lyophilized protein at -20°C to -80 °C for long term.|
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.
|Reconstitution||Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water.|
