FIG. 1.

The immunoreactivity of GXM in different solvents decreased at elevated temperatures. GXM from strain H99 was measured with the Premier Cryptococcal Antigen kit after 4 weeks (A) and 16 weeks (B) of incubation at −20, 4, 37, and 45°C. The samples in the different solvents (four bars for each solvent) were incubated at −20, 4, 37, and 45°C (shown left to right for each solvent). The absorbance of the −20°C samples was set at 100, and the remaining samples were normalized against this value.
