Results of quantification summarized in Table 2 demonstrate that six targets (ADAM10, ALCAM, APMAP, CD58, CD59 and TSPAN9) and CD9 could be quantified in more than 50% (37 cases) of CRC samples, but two targets (ART4 and SELP) were detectable in less than 25% (18 cases) of CRC samples. The gene discussed is APMAP; the disease is colorectal carcinoma.
