Dot blot assay for the serotyping of pneumococci

Development of a recombinant protein-based dot-blot hybridization assay for the detection of antibody to chicken infectious bronchitis virus

Nucleocapsid (N) protein of infectious bronchitis virus (IBV), one of the viral structural proteins, inducesstrong antibody response in natural infection. In this study, a simple, recombinant N protein-based dot-blottest was developed to serologically examine chicken serum samples for the presence of IBV antibody.Initially, 72 serum samples were tested for the presence of IBV antibody using a c...

Serotyping of Cryptococcus neoformans by dot enzyme assay.

A method is described for the serotyping of Cryptococcus neoformans based on direct analysis of culture supernatants for the major type-specific capsular antigen, glucuronoxylomannan. Factor sera prepared by absorption of polyclonal rabbit antisera (Iatron Laboratories, Inc., Tokyo, Japan) or selected anti-C. neoformans monoclonal antibodies were used in a dot enzyme assay to detect the presenc...

Polyclonal Antibodies Pneumococci with Monoclonal and Rapid Multiplex Assay for Serotyping

Rapid multiplex assay for serotyping pneumococci with monoclonal and polyclonal antibodies.

We have developed and characterized a rapid semiautomated pneumococcal serotyping system incorporating a pneumococcal lysate preparation protocol and a multiplex serotyping assay. The lysate preparation incorporates a bile solubility test to confirm pneumococcal identification that also enhances assay specificity. The multiplex serotyping assay consists of 24 assays specific for 36 serotypes: s...
