Antisera, Strains, Antigens

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) (article 2). CWPS Multi consists of 50% CWPS1 and 50% CWPS2.

Pneumococcus antisera are manufactured for the capsular reaction test (Neufeld) or latex agglutination. All
antisera are polyclonal and produced in rabbits.. The specific pool, group and type antisera are absorbed free of
cross-reactions. Factor antisera are absorbed free of cross-reactions within the group.

SSI Diagnostica produces more than 200 different Salmonella antisera, making it possible to type 99% of all Salmonella serotypes.

SSI Diagnostica’s antisera are high quality, CE-marked and produced in accordance with DS/EN ISO 13485. The shelf life is 4 years from the date of production, and minimum 2 years from date of shipment.
