Neurofilament Heavy Antibody [clone RT97] (V2213)

Description

This antibody reacts with a 200kDa protein, identified as heavy subunit of neurofilaments, or NF-H. Neurofilaments make up the main structural elements of axons and dendrites and are found in neurons, peripheral nerves, and sympathetic ganglion cells. Neurofilaments consist of three major subunits with molecular weights of 68kDa (NF-L), 160kDa (NF-M) and 200kDa (NF-H), plus alpha internexin or peripherin. Each neurofilament subunit contains a globular head, an alpha helical rod domain, and variable tail domains that differ in length and amino acid content.

Neurofilament antibody stains a number of neural, neuroendocrine, and endocrine tumors. Neuromas, ganglioneuromas, gangliogliomas, ganglioneuroblastomas, and neuroblastomas stain positively for neurofilament antibody. Neurofilaments are also present in paragangliomas as well as adrenal and extra-adrenal pheochromocytomas. Carcinoids, neuroendocrine carcinomas of the skin, and cell carcinomas of the lung also express neurofilament.

Application Notes

The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the antibody to be titered up or down for optimal performance.

1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

Immunogen

The triton-X 100 insoluble protein fraction of rat brain was used as the immunogen for this Neurofilament Heavy antibody.

Storage

Store the Neurofilament Heavy antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
