Streptococcus Antisera for Precipitation
Confirmation of streptococci is important prior to serotyping.
Streptococcus antisera are polyclonal antibodies produced by immunising rabbits.
Our Streptococcus antisera are manufactured free of cross-reactions with known strains in vials with 1 mL ready-to-use antiserum. This is sufficient for a minimum of 50 reactions.

How to use
Streptococcus antisera are used for precipitation of Lancefield extracts in a capillary tube.
Equal quantities of antiserum and extract are drawn up into a capillary tube – the serum uppermost, as the serum must diffuse down through the extract, and a precipitate is visualized for a positive reaction.
SSI Diagnostica offers antisera to identify the 10 B types and the 5 S. suis types.

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.
