Extract of pigmented melanoma metastases from lymph nodes. Cellular Localization: Cytoplasmic

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. Anti-HMB-45 stains fetal and neonatal melanocytes, junctional and blue nevus cells, and malignant melanoma. This MAb also stains Angiomyolipoma (PEComa).

Applications: 
Suitable for use in Immunofluorescence, ELISA, Flow Cytometry, Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
Flow Cytometry: 0.5-1ug/10e6 cells 
Immunofluorescence: 0.5-1ug/ml 
Western Blot: 0.5-1.0ug/ml 
Immunoprecipitation: 0.5-1ug/500ug protein lysate
Immunohistochemistry (Frozen & Formalin-fixed): 0.5-1ug/ml for 30 minutes at RT. 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
Optimal dilutions to be determined by the researcher.

Positive Control:
SK-MEL-28 cells or Melanoma

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
