Anti-CGA Antibody

Antibodies.com presents a rabbit polyclonal antibody raised against human Chromogranin A (CGA), a 49 kDa acidic glycoprotein stored in the secretory granules of neuroendocrine cells. This unconjugated primary antibody is supplied at 1 mg/ml in PBS with 0.1% Sodium Azide and 50% glycerol as a stabiliser, and ships as a 100 µl vial ready for use in western blot, immunohistochemistry, and immunofluorescence workflows.

Chromogranin A is widely used as a pan-neuroendocrine marker in studies of pancreatic islet cells, adrenal medulla chromaffin cells, pituitary corticotrophs, and gastrointestinal enterochromaffin populations, making this reagent useful for characterising neuroendocrine tumours and related pathologies. The antibody is reactive with human tissue and supports both frozen and formalin-fixed paraffin-embedded sections, enabling application in pathology and basic research laboratories investigating granule biogenesis, hormone secretion, and tumour diagnostics.

For best results, refrigerate the vial on arrival, keep it protected from light, and avoid repeated freeze-thaw cycles; the included glycerol cryoprotectant preserves antibody activity for short-term handling at room temperature during assay setup. Researchers working on neuroendocrine biology, peptide hormone processing, or chromaffin cell biology will find this polyclonal reagent from Antibodies.com a practical tool for probing endogenous CGA expression across multiple detection platforms.
