Chromogranin A Antibody (PHE5) [CoraFluor™ 1]

CoraFluor™ 1, amine reactive (Catalog:7920) and CoraFluor™ 2, amine reactive (Catalog # 7950) are terbium-based probes that have been developed for use as TR-FRET donors. They emit wavelengths compatible with commonly used fluorescent acceptor dyes such as BODIPY® (or BDY) and Janelia Fluor® dyes, FITC (Catalog # 5440), TMR and Cyanine 5 (Catalog # 5436). CoraFluor™ fluorescence is brighter and more stable in biological media than existing TR-FRET donors, leading to enhanced sensitivity and improved data generation. CoraFluor™ 1 exhibits excitation upon exposure to a 337 nm UV laser.

• Reactivity: Hu, Pm, Mu(-), Rt(-)
• Applications: Flow, ICC/IF, IHC, CyTOF-ready
• Clone: PHE5
• Clonality: Monoclonal

Chromogranin A Antibody (PHE5) [CoraFluor™ 1] Summary

• Description: CoraFluor(TM) 1 is a high performance terbium-based TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) or TRF (Time-Resolved Fluorescence) donor for high throughput assay development. CoraFluor(TM) 1 absorbs UV light at approximately 340 nm, and emits at approximately 490 nm, 545 nm, 585 nm and 620 nm. It is compatible with common acceptor dyes that absorb at the emission wavelengths of CoraFluor(TM) 1. CoraFluor(TM) 1 can be used for the development of robust and scalable TR-FRET binding assays such as target engagement, ternary complex, protein-protein interaction and protein quantification assays.

• Immunogen: Human pheochromocytoma (Uniprot: P10645)
• Specificity: 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.

Background

Chromogranin A (CgA) is an 86 kDa protein that is the major member of the granin family of acidic secretory glycoproteins located in neuroendocrine cells. CgA is believed to play a role in targeting peptide hormones and neurotransmitters to granules of the regulated pathways and inhibit hormone and neurotransmitter release. Also, the widespread distribution of CgA has made the measurement of circulating immunoreactive CgA a valuable tool in the diagnosis of neuroendocrine neoplasia, and CgA immunohistochemistry can help to identify the neuroendocrine nature of tumors. The N-terminal domain of CgA inhibits tumor necrosis factor a (TNFa) induced gap formation in human umbilical venous endothelial cells. CgA levels which reflect neuroendocrine differentiation of prostatic carcinoma may have a diagnostic, therapeutic and prognostic role in the management of prostate cancer patients.

FAQs for Chromogranin A Antibody (NBP2-34709CL1). (Showing 1 - 1 of 1 FAQ).

1. I have following question about antibodies against Chromogranin A. Your products list the species but canine is not included. Does it mean that the products cannot be used on canine tissues?
   • When we do not list a species, it means we have not tested an antibody to work with those samples. If we test an antibody and find that it does not work, we will list the species with a minus sign. Unfortunately, we haven't tried these abs on canine tissues and they may work, but we cannot guarantee it. If you would like to purchase one to try, you will be eligible for the Innovators Reward Program.
