Description

The polyclonal antibody reacts with Sp17; the antibody was raised against a peptide mapping to the carboxy terminal domain of human Sp17. The highly immunogenic cancer-testis antigen Sp17 was originally thought to be expressed exclusively in the testis with the primary function of binding the extra cellular matrix of the oocyte (1,2). Upon further investigation Sp17 was found to be expressed by tumor cells with multiple myeloma in up to 30% of the cases studied (3,4). Sp17 has three functional domains, N-terminal, central, and C-terminal domains. The N-terminal domain contains an A-kinase anchoring protein binding motif. The central domain is necessary for heparin binding and the C-terminal domain contains a calmodulin-binding domain (1&2).

Applications Reported

For research use only, not for diagnostic or therapeutic use. Purified anti-human Sp17 poly has been reported for use in immunoblotting (WB).

Applications Tested

Purified anti-human Sp17 poly has been tested by immunoblotting (WB). (1:200 starting dilution). It is recommended that this antibody be titrated for optimal performance in the assay of interest.
