FIG. 1.

Map showing the hypervariable (part I), semiconserved (part II), and highly conserved anchor (part III) regions of VSP AS6 (CRP170) (4, 47). The amino acid length of each region is indicated based on the conventions of Bienz et al. (8) and Muller et al. (53). The location of the 140-amino-acid VSP1 fragment targeted for amplification in this work is indicated beneath the map by a bracket. The location of the GGCY motif, 47 amino acids from the amino terminus of part II, is indicated by an arrow.
