Effective but not very stable.
By Anonymous on 10/25/2018
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: Hepatocyte

Used as GPCR inhibitor for Glucagon treatment in mouse primary hepatocytes. As shown in the picture, from left to right, 1st sample is untreated, 2nd sample was treated with Glucagon, 3rd sample was pre-treated with this chemical plus glucagon, seems pretty effective for inhibiting glucagon stimulated p-CREB activation. however this chemical is not very stable, seems to loose effectiveness after short storage. Overall is happy with this product.
