Merck, GF440, HumanKine® TGF beta 2, Human Recombinant Xeno-Free

General description
HumanKine growth factors are expressed in a proprietary human 293 protein expression system and are manufactured without the use of any animal products and are considered Xeno-Free.
Transforming Growth Factor- beta2 (TGFb2) is a member of a superfamily of homologous, disulfide-linked, homodimeric proteins that regulate the proliferation and differentiation of normal and transformed cells. TGfb2 regulates proliferation, differentiation, adhesion, migration, and other functions in many cell types by transducing their signal through combinations of transmembrane type I and type II receptors (TGFBR1 and TGFBR2) and their downstream effectors, the SMAD proteins. Disruption of the TGFB/SMAD pathway has been implicated in a variety of human cancers.
Physical form
Product is presented in 50mM NaOAc pH 4.5 and filtered through a 0.2 micron filter before lyophilization.
Preparation Note
Store at -20°C for up to 4 months from date of receipt. Further dilutions should be made into appropriate buffer or medium to which protein has been added.
Analysis Note
Bioactivity assay: Determined by the dose dependent inhibition of IL-4 induced proliferation of mouse HT-2 cells (BALB/c spleen activated by sheep erythrocytes in the presence of IL-2). ED50 is typically 0.1-0.5 ng/ml.
HumanKine TGF beta2 is manufactured using all non-animal reagents and is considered Xeno-Free
