Experimental details: Immunofluorescence analysis of Chga was performed using 70% confluent log phase SH-SY5Y cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with Chromogranin A Monoclonal Antibody (PHE5) (Product # MA5-13281) at 1:100 dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor™ Plus 488 (Product # A32766), (1:2000), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e represents merged image of PTI treated IMR-32 (negative expressor of CHGA). Panel f represents cells (SHSY5Y, 1X PTI treated) with no primary antibody to assess background. The images were captured at 60X magnification.

Experimental details: Immunohistochemistry was performed on human colon tissue. Tissue was deparaffinized with xylene, followed by rehydration in sequential washes of 100% ethanol, 95% ethanol, 80% ethanol, 70% ethanol, and water. To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0) and heated for 8-15 min. Following antigen retrieval, tissues were blocked in a 3% H2O2-methanol solution for 15 minutes at room temperature. Tissue was then probed with a Chromogranin A Mouse Monoclonal antibody (Product # MA5-13281) at a dilution of 1:100 in 3% BSA in PBS overnight at 4°C in a humidified chamber. Negative control tissue received no primary antibody. Tissues were washed extensively with PBST, and detection was performed using a goat anti-mouse IgG-HRP secondary antibody at a dilution of 1:500 followed by colorimetric detection using metal enhanced DAB. Tissues were then counterstained with hematoxylin and prepped for mounting and imaging.
