An assay, the paper radioallergosorbent test (PRAST), tor the measurement of specific serum IgE antibody in the rat is described in detail. This assay has been used, in conjunction with a modified PRAST for the determination of relative specific serum IgG antibody and the PRIST assay for total serum IgE [13], to measure specific IgE and IgG and total IgE immune responses in normal parasite infected rats immunized using various protocols. The results indicate that there is a relationship between the basic IgE level and the immune response, i.e. a rat strain with a low constitutive IgE level demonstrates a weak response whereas a high level strain reacts strongly. When PRAST and passive cutaneous anaphylaxis (PCA) were compared, using standardized IgE antibody containing sera, the results were in good agreement. However. PRAST is the preferable assay as it shows less intrinsic variation, is more sensitive than PCA, and is not influenced by high serum IgE levels in the recipient animal.
