ImmuView® S. Pneumoniae Antigen Test

A rapid test that detects all pneumococcus serotypes with high sensitivity and specificity in both urine and cerebrospinal fluid (CSF) and offers broader detection of all pneumococcal serotypes. 

Bacterial Strains

  • The strains are for in vitro use for testing purposes, e.g. serotype determination, and may not be used for commercial purposes (e.g. sale, production of vaccines and antibodies) without prior written agreement with SSI Diagnostica.

Pneumococcal Antigens

SSI Diagnostica’s expert knowledge in producing antigens has been used in the production of reagents for in vitro diagnostics and research.

Pneumococcal Capsule Sugar

SSI Diagnostica offers 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 10mg lyophilized capsular polysaccharides.

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.

Simpler for the better

If you work within the field of microbiology, you might be familiar with Occam’s Razor. At SSI Diagnostica, we champion a slightly adapted version of this principle:
The simplest solution is usually the best one.
