Cryptococcus Neoformans Serotype A, antigen


Each aliquot contains 1 ml of polysaccharide antigen suspension obtained from cultured Cryptococcus neoformans serotype A. The identification of this organism was confirmed by 26S sequencing. The purity of the culture was monitored by Gram staining and by additional culturing. This control is supplied in 0.2 M NaCl.

This reagent is not a substitute for the mandatory positive control reagents provided with licensed test kits. This preparation of Cryptococcus neoformans polysaccharide antigens is formulated for use as an external run control for enzyme immunoassays, latex agglutination methods, and immunochromatographic assays. Polysaccharide antigens may be included in a test run following the procedure provided by the test kit manufacturer for unknown specimens. Polysaccharide antigens can be used for training, lot-to-lot comparison of reagent test kits and comparison of laboratory performances. It is the responsibility of each laboratory to determine the suitability of polysaccharide antigens reagent for their particular use. They also must establish guidelines for the interpretation of the results.
