Production of Monoclonal Antibody against Scrippsiella trochoidea Cysts and Its Application to Analysis during Cyst Formation and Enzyme-linked Immunosorbent Assay

Abstract

A monoclonal antibody was produced by the fusion of mouse myeloma cells with spleen cells from a mouse immunized with the cysts of Scrippsiella trochoidea, marine phytoplankton. Immunofluorescence micro-scopic observation showed that the antibody reacted with the spines on the cyst but not with the vegetative cells and cyst walls. An enzyme-linked immunosorbent assay could be used to measure the cysts in muddy bottom sediments using the purified antibody conjugated with horseradish peroxidase.
