Figure 4From: Tumor-infiltrating B lymphocytes as an efficient source of highly specific immunoglobulins recognizing tumor cellsOrigin of anti-MCF7 scFv antibodies. One Ī¼L of each scFv phage library was amplified by PCR using oligonucleotide primers specific for analyzed antibody genes. Corresponding PEG-purified phage was used as positive control (last line). The irrelevant anti-SP2 antibody gene of known origin, selected earlier from scFvEC23 library, was also tested.Back to article page
