Description

PA1-058 detects prohormone convertase 2 (PC2) from human and mouse alpha pancreas cells. PA1-058 has been successfully used in ICC/IF and Western blot procedures. By Western blot, this antibody detects an ~65 kDa protein representing PC2 from alpha TC 6 cell extract. This antibody is not recommended for Neuro-2a cells in immunfluorescent applications. The PA1-058 immunogen is a synthetic peptide corresponding to residues E(622) L D E A V E R S L Q S I L R K N(638) of mouse PC2. This sequence is completely conserved between mouse and rat protein. PA1-058 synthetic peptide (PEP-138) is available for use in neutralization and control experiments.

Experimental details

Immunofluorescent analysis of PC2 (green) showing staining in the cytoplasm of C2C12 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a PC2 polyclonal antibody (Product # PA1-058) in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4 ºC in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.
