Group A streptococci (GAS) are gram-positive, non-motile, non-spore-forming organisms that appear as pairs or short-to-moderate-sized chains. Applications: Suitable for use in FLISA and Immunofluorescence. Other applications not tested. Recommended Dilution: Immunofluorescence: 1:10-1:50 Acetone fixation of the antigen source is recommended prior to staining. FLISA: 1:20-1:200 Optimal dilutions to be determined by the researcher.
