TABLE 3.

Sensitivities of antigens detected by MAbs 12C9 and 18E2 to enzyme or chemical treatments as determined by ELISA

Treatment of crude fungal extract	% Relative bindinga
	MAb 12C9	MAb 18E2
None	100	100
PBS alone	98	97
Proteinase K	3	3
Pronase E	2	2
Acetate buffer alone	97	91
Periodate	57	81

^aResults, which correspond to the means of triplicate determinations, are expressed as the binding relative to that of the control performed in the absence of any treatment of the antigens.
