PNEUMOCOCCAL ANTIGENS SSI Diagnostica's expert knowledge in producing antigens has been used in the manufacture of reagents for in vitro diagnostics and research. PNEUMOCOCCAL F ANTIGEN F antigens are produced by purifying the sugar from a non-capsule-bearing pneumococcus. Read more PNEUMOCOCCAL CELL WALL POLYSACCHARIDE CWPS & CWPS MULTI Pneumococci produce a conserved sugar group antigen (CWPS, C-Ps, teichoic acid). Recent research has shown at least two different variants based on the quantity of phosphorylcholine (CWPS1 and CWPS2). CWPS Multi consists of 50 % CWPS1 and 50 % CWPS2. Pneumococcal CWPS and CWPS Multi are used as adsorption material in immunological investigations, such as ELISA antibody assays, to evaluate whether any vaccination/revaccination is desirable. When CWPS Multi is used, adsorption with the 22F capsule, as recommended by WHO for ELISA (article1), is not required. Read more about CWPS Read more about CWPS Multi
PNEUMOCOCCAL CAPSULE SUGAR SSI Diagnostica offers all 91 types of purified pneumococcal capsular polysaccharides. Each specific type has been propagated and purified separately and the specificity verified. The purified polysaccharides are contaminated with approximately 5 % cell wall polysaccharides (CWPS). The purified antigen is supplied in a vial containing 21 mg lyophilized capsular polysaccharides. Read more
