Long description
The mammalian members of the MAGE (melanoma-associated antigen) gene family were originally described as completely silent in normal adult tissues, with the exception of male germ cells and, for some of them, placenta. By contrast, these genes were expressed in various kinds of tumors. MAGE-like genes have also been identified in non-mammalian species, like the zebrafish or Drosophila melanogaster. Although no MAGE homologous sequences have been identified in Caenorhabditis elegans, Saccharomyces cerevisiae or Schizosaccharomyces pombe, MAGE sequences have been found in several vegetal species, including Arabidopsis thaliana. The only region of homology shared by all of the members of the family is a stretch of about 200 amino acids which has been named the MAGE conserved domain. The MAGE conserved domain is usually loCated close to the C-terminal, although it can also be found in a more central position in some proteins. The MAGE conserved domain is generally present as a single copy but it is dupliCated in some proteins. It has been proposed that the MAGE conserved domain of MAGE-D proteins might interact with p75 neurotrophin or related receptors. The function of this protein is not known, though may play a role in embryonal development and tumor transformation or aspects of tumor progression. Antigen recognized on a melanoma by autologous cytolytic T-lymphocytes. The Melanoma-associated antigen is expressed in many tumors of several types, such as melanoma, head and neck squamous cell carcinoma, lung carcinoma and breast carcinoma, but not in normal tissues except for testes and placenta. Never expressed in kidney tumors, leukemias and lymphomas.

Antibody s specificity
NKI/C-3 is a MAb which is directed anti a predominantly intracellular protein of Human melanoma cells. The antigen is abundantly present in malignant melanomas, nevocellular nevi, and neuroendocrine tumors, whereas it has not been detectable in most other tissues. The antigen recognized by NKI/C-3 is a glycoprotein which appears as a broad band in SDS-PAGE. The antigen was shown to consist of a single protein backbone to which two or three .V-linked glycans were added cotranslationally. Extensive further heterogeneity was geneRated in the Golgi compartment and was shown to be dependent on the presence of complex type sugars. Although the antigen is associated with melanomas, it was not codistributed with the tyrosinase activity associated with melanogenesis. The antigen did show codistribution with Cathepsin D, which is a marker for lysosomal functions. NKI/C3 originally was described as a marker for melanoma. Recently, it resurfaced as a marker to sepaRate cellular neurothekeoma from other dermal tumors in the differential diagnosis.

Warnings
This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving humans or animals. This product contains sodium azide. To prevent formation of toxic vapors, do not mix with strong acidic solutions. To prevent formation of potentially explosive metallic azides in metal plumbing, always wash into drain with copious quantities of water.

Test
Mouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.
