Streptococcus antisera for Neufeld and precipitation
Confirmation of streptococci is important prior to serotyping.

Product description
Streptococcus antisera are polyclonal antibodies produced by immunizing rabbits.
Our Streptococcus sera 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 the capsular reaction test (Neufeld) and precipitation.
Neufeld
Equal quantities of antiserum and bacterial culture are mixed on a slide. The preparation is read under a microscope. A positive reaction is indicated by swelling of the cells.
Precipitation
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. A precipitate is visualized for a positive reaction.
