General description
Chromogranin A (CHGA) or CgA is a neuro-secretory protein, and is a member of the granin family. This protein is usually found within chromaffin granules in the adrenal medulla and released along with the catecholamines. This protein is expressed on cells at crypt base in the small intestine.

Chromogranin-A precursor recombinant protein epitope signature tag (PrEST)
Application
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions
CHGA (Chromogranin A) protein concentration is known to be elevated in the serum of rheumatoid arthritis (RA) patients. This secretory protein can act as a panenteroendocrine marker. CHGA interacts with mutant SOD1 (superoxide dismutase 1) to cause amyotrophic lateral sclerosis (ALS) by increasing ROS (reactive oxygen species) production in astrocytes. The encoded protein functions as a modulator of cell adhesion, and regulates the synthesis secretory granule. The quantification of circulating immunoreactive CgA can be used in the diagnosis of neuroendocrine neoplasia, and tissue expression pattern of CgA might aid in discovering neuroendocrine nature of tumours.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

The spatial orientation of the enteroendocrine cells along the crypt-villus axis is closely associated with their differentiation in the intestine. Here we studied this relationship using primary duodenal crypts and an ex vivo organoid system established from cholecystokinin-green fluorescent protein

Prions consist of aggregates of abnormal conformers of the cellular prion protein (PrP(C)). They propagate by recruiting host-encoded PrP(C) although the critical interacting proteins and the reasons for the differences in susceptibility of distinct cell lines and populations are unknown.
