The effect of tris(2-carboxyethyl)phosphine (TCEP).
Dependences of peak H height of Cys, GSH, GSSG, PC2, BSA (A) and its potential (B) on the different TCEP concentration; the picture in inset: chemical structure of TCEP. The influence of TCEP on CPSA signals of 40 fmol MT (5 µl, C). Dependences of peak H height and potential of 40 fmol MT (5 µl) on different TCEP concentration (D). The peak height 55 000 s/V corresponds to 100% (B).
