Immediately after surgical removal the lymph node was cut in half through the cancer lesion and was incubated at 37° C for 3 hrs in 50 ml saline solution containing 2 μCi of 99mTc-mAb to Galectin-3 (0.1 μg protein) and 1% human serum albumin, in presence or absence of 100 μg of unlabelled (cold) anti-galectin-3 mAb (displacement assay). Here, LGALS3 is linked to cancer.
