FIG. 8.
Relative avidity of M-specific MAbs. (A) Binding of MAbs 3D.E3 (●), 3B.B3 (■), and 9D.B4 (▴) and polyclonal serum rabbit anti-GUS (▾) to the TGEV M protein as determined by RIA to estimate the MAb relative avidity for the M protein. (B) Analysis by SDS-PAGE and autoradiography of the M protein immunoprecipitated by these MAbs.
