Product description

K antisera are polyclonal antibodies from rabbits. The antisera are used for serotyping of the 67 known E. coli K antigens.

K antisera are supplied ready for use in 1 mL bottles, which is sufficient for at least 65 tests (50 tests for K9 antisera for slide agglutination). 

How to use 

K antisera are used for current counter immunoelectrophoretic and cannot be used for slide agglutination. 

The only exception is K9 antiserum, article number 84888, which can be used for slide agglutination for the EPEC strain O104:H4. This product was developed during the O104:H4 outbreak in Germany in 2011. It is not intended for general serotyping of K9 capsules.

Product range

SSI Diagnostica Group has K antisera against all defined K antigens. The K antigen series for E. coli is numbered K2–K103. Historically, 32 designations were reclassified (e.g., belonging to other species or to fimbrial—not capsular—antigens), which is why they are not listed in the tables below. The K antigens eventually proved not to be E. coli capsule antigens are K21, K58-K73, K75-K81, K86, K88, K90, K91, and K99. 

Please note that all available E.coli K antisera products are restricted (also indicated by R mark in the table), indicating the potential need for a forecast, minimum order or extra fee. Please contact us via the contact form if you have an inquiry for one of these products.
