ImmuLex™ Streptococcus Antisera



Confirmation of streptococci is important prior to serotyping.

Product description

All SSI Diagnostica latex products are labelled ImmuLex™ (Immunology and Latex). A contraction of Immunology and Latex. Streptococcus antisera for latex are polyclonal antibodies produced by immunising rabbits with killed cells. The serum is then coupled to latex particles.

Our Streptococcus sera for latex testing are manufactured free of cross-reactions with known strains in vials with 1.5 mL ready-to-use antiserum. This is sufficient for a minimum of 75 reactions.


ImmuLex™ Streptococcus products are used for serotyping based on agglutination.

Equal quantities of latex reagent and bacterial culture are mixed on a white card, which is tipped back and forth. The reaction must be read within 30-60 seconds.

Product range

SSI Diagnostica offers latex to identify groups A, B, C, D, F, G, and L, and also the 10 B types.
