antibodypolyclonal antibodyantiserum

Confirmation of streptococci is important prior to serotyping. Product description 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. Streptococcus antisera for serotyping of streptococci High quality We offer experienced technical support Shelf-life of 4 years 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. Product range SSI Diagnostica offers antisera to identify the 10 B types and the 5 S. suis types. F.A.Q. Can I freeze the antibodies? 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. Is it possible to reserve sera from a particular lot? 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. Can I order products that do not appear in the catalogue? You can always send an inquiry. We might have it.
