Abstract
An agglutination reagent is prepared by covalently attaching an immunoreactive species to polymeric particles through reactive groups in the species. After attachment, the species is chemically modified with an acylating, alkylating or sulfonylating agent thereby modifying primary or secondary amino groups. The reagent can be used in agglutination assays for a number of analytes, inclusing Streptococcus A antigen, human retroviruses or antibodies, human chorionic gonadotropin and other antibodies or antigens.
