Description:
Applications:
Suitable for use in Westrn Blot, Immunofluorescence and Immunohistochemistry.

Recommended Dilution:
Immunohistochemistry (Frozen and paraffin sections): 1:10.
No proteolytic pretreatment.
Western Blot: 1:10
Immunofluorescence: 1:10
Optimal dilutions to be determined by the researcher.

Positive Control:
Pancreas and adrenal medulla

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Form
Supplied as a liquid, 0.1% sodium azide. Dilute with TBS before use.
Specificity:
Recognizes human Chromogranin A. Represents an excellent marker for most neuroendocrine, neuronal and adrenal tumors: e.g. pheochromocytoma, paraganglioma, neuroblastoma, pancreatic islet cell carcinoma, gastroadenomas from pituitary and parathyroid gland. Weak reaction with Merkel cell tumors of skin and small cell lung carcinoma. Reacts with the 68kD protein (chromogranin A). The antigen is localized in secretory granules and, therefore, poorly granulated cells react weakly. Species Crossreactivity: monkey, rat, rabbit and porcine.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
