Diagnostic Serum

Antisera are widely used for diagnoses of pathogens, serotyping of clinical isolates in hospitals and many laboratories. Now, we are producing the diagnostic kits for Escherichia coli, Shigella, Salmonella, Vibrio cholerae, Vibrio Parahaemolyticus, Legionella.


The production of antisera was based on international standards and supervised by the expert from Russia, who has more than 20 years experience with antisera production.

We have constructed animal breeding rooms with high quality, which are able to breed hundreds of rabbits at the same time. The rabbits used to injection were healthy, and the antisera were produced following the standard procedures strictly.

We have all the reference strains for E coli O antigens, H antigens, Shigella O antigens, Salmonella O antigens, Streptococcus pneumoniae capsular antigens, and Proteus O antigens, so we have advantages to produce the antisera for the bacteria above.

Produced antisera have been tested with more than 200 other strains (including other serotypes of the same species and related species), the non-specific components have been adsorbed in order to make sure the high specificity of the antisera.

The produced antisera have high titer, and antisera have been purified and aseptic were added. The diluted antisera for use can be saved for 2 years with high titer.
