Scatchard analysis of human anti-GIPC1 monoclonal antibody on antibody on SK-BR-3 cells. Scatchard analysis of human monoclonal antibody 27.F7 performed on SK-BR-3 cells revealed the presence of an antigen target with two affinities. This suggests that two populations of GIPC1 molecules exist in these cells and may be related to the protein doublet identified by Western blot analysis in Figure 2.
