Pertussis toxin impacts GABA-A receptor effects
By Anonymous on 07/21/2019
Application: Species: Rat

Pertussis toxin (PeTX) was used to compare effects of PKA and G-protein signalling on root mean square noise (RMS) produced by GABA-A receptors in electrophysiological recording. We found that after block of G-protein signalling with PeTX GABA-A receptor antagonists SR 95531 and Picrotoxin generate smaller impact on RMS noise than after block of PKA with PKI.

Pertussis Toxin inhibits LPA induced COX-2 expression in osteosarcoma cells
By Christopher Trummer on 10/23/2018
Application: Species: Human

MG-63 cells were treated with LPA (10 µM) alone or in combination with C3 (20 µM), PTX (Pertussis Toxin, 400 ng/ml) or H2L 5765834 (20 µM) for 3 h to follow COX-2 expression using Western blot. Pertussis Toxin inhibited COX-2 expression induced by LPA.

Fast delivery and great quality

Application: Species: Mouse

It was used to block gpcr response before hitting the cells with the ligand for receptor of interest
