Description
BackgroundThe CA-50 ganglioside antigen present in the COLO 205 cell line has been characterized as sislosylfucosyllactotetraosylceramide, which is the sialylated Lewisa pentaglycosylceramide . Because CA 50 is also present in patients who are Lewisa blood group-negative (~5%) and who therefore cannot have the CA 19-9 antigen, a combination of CA 50 and CA 19-9 may be useful for accurate diagnosis of pancreatic neoplasm. Studies using a mAb against the CA-50 ganglioside have demonstrated CA 50 to be a minor component in many different carcinomas.

We can offer labeled proteins/antibodies using a broad range of intensely fluorescent dyes and labels including FITC, Co-Au, biotin, Alexa Fluor, Rhodamine B(RBITC), Cy.
