Stains / Test Description

Antibody specificity was demonstrated by detection of differential expression of the target protein in cell line upon treatment with secretion blockers. This would enable retention of target protein inside the cell. Relative expression of Chromogranin A was observed in SH-SY5Y and IMR-32 cells treated with PTI (1X for 4hr) and with FL1-06 (10uM for 4hr) as compared to the corresponding untreated cells using immunohistochemistry (Paraffin) analysis of Chromogranin A was performed in paraffin-embedded mouse pancreas tissue using Chromogranin A Polyclonal Antibody
