Transforming Growth Factor Beta1, Human (TGFb1) BioAssay ELISA Kit

£942.83 96 Tests

This Transforming Growth Factor beta1, Human (TGFb1) BioAssay ELISA Kit is a 3 hour solid phase immunoassay readily applicable to measure TGFb1 levels in serum, plasma, cell culture supernatant and other biological fluids in the range of 0 to 2500pg/m. It showed no cross reactivity with various other cytokines superfamily proteins. This TGFb1 ELISA kit is expected to be effectively used for further investigations into the relationship between TGFb1 and various diseases.

Transforming Growth Factor beta1, Human (TGFb1) BioGene ELISA Kit, is to be used for the in vitro quantitative determination of human transforming growth factor beta 1 (TGF-b1) concentrations in serum, plasma, cell culture supernatant and other biological fluids. It is intended for research use only and is not for use in diagnostic procedures.
