Product Name: Chromogranin A Antibody [SPM585]
Species Reactivity: Human, Monkey
Tested Applications: Flow, IF, IHC
Applications: Flow Cytometry: 0.5-1 ug/million cells in 0.1mlImmunofluorescence: 0.5-1 ug/mlImmunohistochemistry (FFPE): 0.5-1 ug/ml for 30 minutes at RT (1)Prediluted format: incubate for 30 min at RT (2)The optimal dilution of the Chromogranin A antibody for each application should be determined by the researcher.1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
User Note: Optimal dilutions for each application to be determined by the researcher

Background: Chromogranin A 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, pheochromocytomas, paragangliomas, and other neuroendocrine tumors. Co-expression of chromogranin A and neuron specific enolase (NSE) is common in neuroendocrine neoplasms. Reportedly, co-expression of certain keratins and chromogranin indicates neuroendocrine lineage. The presence of strong anti-chromogranin staining and absence of anti-keratin staining should raise the possibility of paraganglioma. The co-expression of chromogranin and NSE is typical of neuroendocrine neoplasms. Most pituitary adenomas and prolactinomas readily express chromogranin.
