Chromogranin A antibody

SKU: orb2276581

Description

Chromogranin A antibody validated for immunohistochemistry on 76 different Normal Tissues

Images & Validation

• Tested Applications: IHC
• Dilution Range: 1:100-1:200
• Reactivity: Human
• Application Notes:
  Positive Control: Appendix: An at least weak to moderate staining must be seen in the axons and ganglion cells of the peripheral nerves while mucosal neuroendocrine cells exhibit a strong staining (neuroendocrine cells are not sufficient as positive controls because they express CGA so strongly, that even inefficient staining will detect its expression) Negative Control: Appendix: Epithelial and smooth muscle cells should be negative. Cellular Localization: Finely granular cytoplasmic Protocol Recommendations: Manual Protocol: Freshly cut sections should be used (less than 10 days between cutting and staining). Heat-induced antigen retrieval for 5 minutes in an autoclave at 121°C in pH 7.8 Target Retrieval Solution buffer. Apply the antibody at a dilution of 1:150 at 37°C for 60 minutes. Visualization of bound antibody by the EnVision Kit (Dako, Agilent) according to the manufacturer’s directions.
