Medchemexpress LLC TGF beta 1/TGFB1 Mo 2ug
Recombinant TGF-β1 protein (mouse/rat), expressed in HEK293 cells and supplied as a lyophilized, tag-free polypeptide corresponding to residues A279-S390. The protein is >95% pure by reducing SDS-PAGE, has an approximate molecular weight of 13 kDa, and demonstrates potent biological activity in standard cell proliferation assays (ED50 in the pg-ng/mL range). Formulated from a 0.22 μm filtered solution of 4 mM HCl and intended for in vitro signaling and functional assays; store frozen and avoid repeated freeze-thaw by aliquoting.
