Representative results of various immunofluorescence tests for anti-p200 pemphigoid. (A, B) Direct immunofluorescence (DIF) for IgG (A) and C3 (B). (C) Indirect immunofluorescence of normal human skin (IIF) for IgG. (D) Indirect immunofluorescence of 1M NaCl-split normal human skin (ssIIF) for IgG. All these representative results were originated from an anti-p200 pemphigoid patient with mucosal lesions.

Concerning the results of immunofluorescence tests, the positive rates of IgG ( Figure 1A ) and C3 ( Figure 1B ) depositions to BMZ in DIF were 94.4% and 97.1%, respectively, positive IgG reactivity rate in IIF of normal human skin ( Figure 1C ) was 80.0%, and positive IgG reactivity with dermal side in ssIIF ( Figure 1D ) was 97.2%.
