Application Details

Application Notes: The optimal dilution of the gp100 antibody for each application should be determined by the researcher.

1. Staining of formalin-fixed tissues requires boiling tissue sections in pH 9 10 mM Tris with 1 mM EDTA 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.

Restrictions: For Research Use only

Handling

Target Details for Melanoma gp100

Target: Melanoma gp100 (PMEL) (Premelanosome Protein (PMEL))

Alternative Name: gp100

Background: By immunohistochemistry, it specifically recognizes a protein in melanocytes and melanomas. This mAb reacts with junctional and blue nevus cells and variably with fetal and neonatal melanocytes. Intradermal nevi, normal adult melanocytes, and non-melanocytic cells are negative. It does not stain tumor cells of epithelial, lymphoid, glial, or mesenchymal origin. Metastatic amelanotic melanoma can often be confused with a variety of poorly differentiated carcinomas, large cell lymphomas, and sarcomas using H & E stains alone. It is also difficult to differentiate melanoma from spindle cell carcinomas and various types of mesenchymal neoplasms. It stains fetal and neonatal melanocytes, junctional and blue nevus cells, and malignant melanoma.

The gp100 Molecule is a 100 kDa glycosylated protein that is cleaved into a small (26 kDa) carboxy-terminal fragment and a larger amino- terminal section (60-64 kDa), which is subsequently cleaved to generate 26 kDa and 34-38 kDa fragments.
