CHARACTERIZATION OF POLYCLONAL ANTIBODIES AGAINST OVINE ADIPOCYTE PLASMA-MEMBRANES

1. Antisera against ovine adipocyte plasma membranes were developed in a mare.2. These antisera showed a high degree of specificity to adipo cyte plasma membranes and cross-reacted with other tissues. 3. Antiser a cross-reactivity can be removed by adsorption of the antiserum with various tissue plasma membranes without significant reduction in their reactivity to adipocyte plasma membranes. 4. Antisera reacted with di fferent affinity to adipocyte plasma membranes from different sites an d from different species of animals.
