title: Hybrid hybridoma cell lines which express anti-zeatin riboside, anti-abscisic Acid, and hybrid antibodies.
abstract: Hybrid hybridoma cell lines that secreted antibodies which reacted with two distinct plant hormones, abscisic acid (ABA) and zeatin riboside (ZR) were prepared and cloned. These cell lines were derived by polyethylene glycol-mediated fusion of HAT-sensitive anti-ZR hybridoma cells with splenocytes harvested from a BALB/c mouse previously immunized with an ABA-bovine serum albumin conjugate. Chromatographic analyses indicated that these lines expressed two different isotypes, each associated with a specific immunologic reactivity, and that the populations of immunoglobulins secreted by these hybridomas included antibodies directed against each individual hapten as well as hybrid molecules which reacted simultaneously with both. Hybrid hybridomas such as these should provide antibody populations useful for simultaneous isolation of multiple plant hormones from individual plant samples.
