The yield of galectin-1 binding proteins from the healthy sera was on average 1.2 mg per ml serum (range 0.7–2.2), whereas the yield from the cancer sera was significantly (p<0.0001) higher with an average of 2.2 mg per ml serum (range 0.8–3.9) (Fig. 2B). The gene discussed is LGALS1; the disease is cancer.
