FIG. 4.

Epitopes of Tf190 vary between strains and within the same strain of T. foetus. (A) Western blots of whole-cell extracts of five strains of T. foetus (Y-32, lane 1; BP-4, lane 2; 17509, lane 3; BQM, lane 4; 330.1, lane 5) were reacted with MAb 32.8D3.2, 34.5D4.10, or 32.3B3.5 as indicated. (B) Western blot of whole 330.1 reacted with six different MAbs. Lane 1, 32.8D3.2; lane 2, 32.1B4.3; lane 3, 34.5D4.10; lane 4, 32.3B3.3; lane 5, 32.3B3.5; lane 6, 32.1B4.2; lane 7, no primary antibody. Molecular sizes in thousands are indicated on the right of each panel.
