The coccidioidal complement fixation and immunodiffusion-complement fixation antigen is a chitinase.

Culture filtrates and autolysates of Coccidioides immitis have provided suitable crude antigens for the serodiagnosis and prognosis of coccidioidomycosis. One of these, a heat-labile antigen which participates in the immunodiffusion reaction corresponding to the complement fixation reaction (IDCF), has been characterized as a 110-kDa native protein that, when subjected to reducing conditions an...

Comparison of immunodiffusion techniques with standard complement fixation assay for quantitation of coccidioidal antibodies.

Quantitative immunodiffusion (QID) and complement fixation (CF) methods were compared for their agreement in detecting coccidioidal antibodies. For these studies, we assayed 719 sera from 181 patients with coccidioidomycosis. Over 60% of the specimens had CF results of 1:2 to 1:256. A total of 43 patients had five or more specimens obtained over periods of between 1 and 8 years. The QID method,...

Amino-terminal sequence analysis of the Coccidioides immitis chitinase/immunodiffusion-complement fixation protein.

A chitinase isolated from Coccidioides immitis was subjected to amino-terminal protein sequence analysis. The resulting 18-amino-acid sequence was compared with the previously reported amino acid sequence of coccidioidal immunodiffusion-complement fixation (IDCF) antigen. From the homology of the two sequences, the results support the identification of the IDCF antigen with a chitinase.

Factors affecting assay of myoglobin by complement fixation or immunodiffusion.

Quantitative micro-scale complement-fixation and semi-quantitative gel immunodiffusion assays for myoglobin have been evaluated experimentally and used to measure myoglobin in the sera of more than 1500 patients. We report certain problems, observations, and methodological improvements. Serum caused enhancement of precipitin lines in the immunodiffusion assay. In the complement-fixation assay,...
