Product Info
Background 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). 
Origin Sp17 (C17) is provided as an affinity purified rabbit polyclonal antibody, raised against a peptide mapping to the carboxy terminal domain of human Sp17. 
Product Details Each vial contains 200 g/ml of affinity purified rabbit IgG, Sp17 (C17) DB074, in 1 ml PBS containing 0.1 % sodium azide and 0.2% gelatin. 
Competition Studies A blocking peptide is also available, DB074P, for use in competition studies. Each vial contains 0.100 mg of peptide in 0.5 ml PBS with 0.1% sodium azide and 100 mg BSA. 
Form 200 g/ml rabbit polyclonal IgG in 1 ml PBS containing 0.1 % sodium azide and 0.2% gelatin. 
Immunogen Synthetic peptide mapping to the carboxy terminal domain of human Sp17. 
Specificity Sp17 (C17) is recommended to detect human Sp17 
Use Western blotting, recommended western blotting starting dilution 1:200.
