FIG. 1.

Immunoblot from a 12.5% SDS-PAGE showing A. fumigatus proteins reacting with rabbit serum obtained either prior to infection (A) or 14 days after infection (B). Lane 1, cell wall extract; lane 2, intracellular extract. The infectious serum tested corresponds to the second infectious serum of rabbit no. 2 (Table 1, serum identifier 2b) which was gained 2 weeks after a second challenge with 50,000 conidia (compare with Fig. 2).
