Scatchard plots are based on repeated equilibrium dialyses with a constant concentration of antibody and varying concentration of ligand. 

If all antibodies have the same affinity, then a Scatchard plot yields a straight line with a slope of Ka. The x intercept is n, the valency of the antibody, which is 2 for IgG and other divalent Igs. For IgM, which is pentameric, n  10, and for dimeric IgA, n  4. In this graph, antibody #1 has a higher affinity than antibody #2. .

MMP2 is a protein that digests extracellular matrices (such as the zona) and may be responsible for digesting a pathway to the oocyte Acrosin bind secondarily to the zona, keeping the sperm in the channel it creates
