Immulex Streptococcus

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.

Streptococcus antisera for serotyping of streptococci

High quality

We offer experienced technical support

Shelf-life of 4 years

How to use

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 seconds.

Product range

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

F.A.Q.

Click the question to get your answer

Antibodies can be frozen, but the process of freezing and thawing is damaging for the antibodies, and the titer will drop (even though not dramatically) due to decomposition. We have not made further studies on this, and cannot guarantee the stability of the sera, but we have experienced that mostly the titer stays at the same level if a serum only is frozen and thawn once.

Yes, it is possible, if you place an order in advance with the expected total volume for the period. In return we guarantee to keep the reserved lot for you.

You can always send an inquiry. We might have it. Depending on the needed volume, we might be able to develop the requested product. It can be anything from a new pool composition to a new serum.
