Application
Immunocytochemical analysis of Calnexin in COS7 cells. Transfected COS7 cells were blocked in 1% BSA, 5% normal goat serum, and 0.1% Triton X-100 in 1X PBS, and then stained (1:500), followed by a fluorophore-conjugated secondary antibody (red). Magnification = 100X.
Application
Immunohistochemistry was performed on cancer biopsies of deparaffinized human hepatocarcinoma tissues. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:20 with or without Calnexin antibody [AF18] overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.
