Assessment of virus infectivity by the immunofluorescent and immunoperoxidase techniques.

Application of Specific Monoclonal Antibodies for Characterization of Leishmania spp. Promastigotes Using Indirect Immunofluorescent and Immunoperoxidase Tests

Background: Different methods have been used for characterization of Leishmania promastigotes. Monoclonal antibodies are useful in characterization of   Leishmania spp . both amastogotes and promastigotes. Objective: Comparing the characterization of   Leishmania spp. promastigotes with immunoperoxidase test (Avidin-Biotin) techniques and an indirect immunofluorescent assay (IFA).   Methods: Ap...

An infectivity assay for bovine leukemia virus using the immunoperoxidase technique.

This report describes the development of a 7-day infectivity assay for bovine leukemia virus (BLV) which is based on the induction of the major internal virion antigen (a protein with a molecular weight of 25,000) in susceptible indicator monolayer cell cultures. In this assay, the antigen is detected in the indicator cells by the immunoperoxidase antibody technique using a specific rabbit anti...

Impact of cell culture sensitivity and virus concentration on rapid detection of herpes simplex virus by cytopathic effects and immunoperoxidase staining.

Tremendous interest has been generated in the commercial kits now available that incorporate herpes simplex virus isolation in cell culture with immunoperoxidase staining for viral antigen detection. Most studies comparing commercial kits with conventional cell culture techniques have found the kits to be less sensitive. However, different cell cultures were used for the two methods. In this st...
