Antinuclear antibodies were detected by immunofluorescence in most sera from rabbits immunized with whole human serum emulsified in Freund's complete adjuvant. Four of 14 sera from rabbits immunized with Cohn fractions III, IV-1, or IV-4 also gave positive nuclear fluorescence with human leukocyte nuclei. Other human and animal nuclei gave negative results with these rabbit antisera. Three rabb...

OBJECTIVES To produce antisera to the 15 recognised reference strains of the Kielstein-Rapp-Gabrielson (KRG) serotyping scheme for Haemophilus parasuis, validate those sera and use them to serotype 46 Australian field isolates of H parasuis. DESIGN Antisera were produced in rabbits and validated by cross-testing with the reference strains and re-testing 15 Australian field isolates of H paras...

Rotavirus antisera with and without neutralizing activity to calf rotavirus were compared for their ability to agglutinate calf rotavirus particles with and without an outer capsid layer. Particles without the outer capsid layer were agglutinated by antisera with immunofluorescent antibody activity and by antisera with immunofluorescent antibody and neutralizing activity. Particles with the out...

This paper describes the specificity of AKR anti-(a) [AKR anti-trinitrophenylated AKR (AKR-TNP)] [AKRa (AKRaAKR TNP)] antisera raised in syngeneic AKR mice against AKRaAKR-TNP cell populations enriched for H-2-restricted aTNP cytotoxic lymphocytes (CTL) by blast-cell isolation. The activity of the antisera resided in the Ig fraction. All antisera were shown to reproducibly react with AKRaAKR-TN...

Antisera have been raised against two peptides from the sequence of D2 dopamine receptors: peptide 1 from the predicted second extracellular loop and peptide 2 from the predicted third intracellular loop. The antisera recognize specifically a 95 kDa band in Western blots of several bovine brain regions, which corresponds to the denatured D2 dopamine receptor, whereas in recombinant CHO cells ex...

Studies of the relative combining capacities of different antisera to Vibrio cholerae and Shigella flexneri were carried out using the Talmage test. In this test the absorption of an I(131) labelled antibody preparation by antigen is blocked by the addition of unlabelled unknown serum. Sera from rabbits in the early stages of immunization ("early antisera") had a high agglutinin titer, but low ...
