Technical Data
C5069-96G1
Chromogranin A (CGA, CHG A, Pancreastatin, Parathyroid secretory protein 1, Pituitary secretory protein I, Vasostatin, SPI) (BSA Free)
Description:
Chromogranin A (a protein of 439 amino acid which is encoded on chromosome 14) is present in neuroendocrine cells throughout the body, including the neuroendocrine cells of the large and small intestine, adrenal medulla and pancreatic islets. It is an excellent marker for carcinoid tumors, phenochromocytomas, paragangliomas, and other neuroendocrine tumors. Coexpression of chromogranin A and neuron specific enolase (NSE) is common in neuroendocrine neoplasms.

Applications:
Suitable for use in ELISA and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
Immunohistochemistry (Formalin/paraffin): 1:400 for 30 minutes at RT. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 minutes followed by cooling at RT for 20 minutes.
Optimal dilutions to be determined by the researcher.

Positive Control:
Pancreas

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
