Human Mature TGF beta 1 Protein
Recombinant Human Mature TGF beta 1 Protein is expressed from HEK293 without tag. It contains Ala279-Ser390.[Accession | P01137]
The protein has a predicted MW of 13.2 kDa (monomer). Due to glycosylation, the protein migrates to 14-15 kDa (monomer) under reduced (R) condition and 26-30 kDa (dimer) under Non reducing (N) condition based on Tris-Bis PAGE result.
Less than 1EU per μg by the LAL method.
> 95% as determined by Tris-Bis PAGE
Lyophilized from 0.22μm filtered solution in 50mM Glycine 150mM NaCl (pH 2.5). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in 4mM HCl.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Human Mature TGF beta 1 on Tris-Bis PAGE under reduced (R) condition and Non reducing (N) condition. The purity is greater than 95%.
Immobilized Human Mature TGF beta 1, No Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human TGF-beta RII, mFc Tag with the EC50 of 3.8ng/ml determined by ELISA (QC Test).
Human TGFBR1, mFc Tag captured on CM5 Chip via Protein A can bind Human Mature TGF beta 1, No Tag with an affinity constant of 0.35 μM as determined in SPR assay (Biacore T200).
Measured by its ability to inhibit cell proliferation of Mv-1-lu mink lung epithelial cells. The ED50 for this effect is typically 0.1-0.2 ng/mL.
TGF-beta 1 (transforming growth factor beta 1) is one of three closely related mammalian members of the large TGF-beta superfamily that share a characteristic cystine knot structure. TGF-beta 1, -2 and -3 are highly pleiotropic cytokines that are proposed to act as cellular switches that regulate processes such as immune function, proliferation and epithelial-mesenchymal transition.Transforming growth factor beta-1 is multifunctional protein that regulates the growth and differentiation of various cell types and is involved in various processes, such as normal development, immune function, microglia function and responses to neurodegeneration.
