Stable rabbit-mouse hybridomas and secretion products thereof

摘要

Rabbit-mouse hybridomas are cultured immediately after fusion in a suspension medium supplemented with normal rabbit serum. This results in stable hybridomas and provides a source of intact rabbit monoclonal antibody immunoglobulin of defined specificity. A hybridoma which secretes intact rabbit antibody specific for Group A Streptococcus is exemplified. Diagnostic compositions and test kits containing rabbit monoclonal antibodies produced from such hybridomas are described. PPThis application is a continuation of application Ser. No. 07/189,754, filed May 3, 1988, which in turn is a continuation-in-part of application Ser. No.: 046,439, filed May 4, 1987, now abandoned.
