Chromogranin B (Secretogranin I) — frequently asked
What is chromogranin B?
Chromogranin B, also called secretogranin I, is an acidic granin protein stored in the dense-core secretory granules of neuroendocrine cells and neurons. It is described as contributing to granule biogenesis and as a precursor for several shorter derived peptides.
Why are prepro fragments supplied?
Prepro sequences correspond to regions of the full translation product, including parts outside the mature processed peptides. They are used as immunogens and blocking peptides when researchers want antibodies that report on precursor expression or on specific processing intermediates.
What is chromogranin B used to study?
It serves widely as a marker of the regulated secretory pathway and of neuroendocrine cell identity, and as a model for studying prohormone processing at paired basic residues. Processing patterns vary by tissue, so results are interpreted in context.
