... TGF bioassay. To quantify the levels of active and total TGF, we used mink lung epithelial cells (MLEC) that produce luciferase under the control of the PAI-1 promoter in response to TGF (gift from Daniel Rifkin, New York University) (Abe et al., 1994). MLEC were plated at 7.8 x 104 cells/cm2, al ...

A competitive inhibitor will bind to the active site of an enzyme (where the substrate or reactant would usually bind) and prevent the substrate from ...

The lesions repaired by TCR in those regions might be very minimal as compared to the remainder of the genome. Therefore, ...
