Detection of soluble ULBP3 (sULBP3) from tumor cells and in the serum of cancer patients.

sULBP3 in serum samples from cancer patients or in the culture supernatant of tumor cell lines was measured by time-resolved fluoroimmunoassay (TRFIA), as described in the Materials and Methods section. (A) Standard curve for the detection of the sULBP3. (B) sULBP3 levels in the culture supernatant of cancer cell lines. (C) sULBP3 levels in the serum of healthy volunteers (n = 48) and patients with colorectal caner (n = 45), gastric cancer (n = 38), or lung cancer (n = 33). The results are expressed as the mean ± SEM. ***P < 0.001.
