PREPARATION OF SPECIFIC ANTISERA TO HONEYBEE VIRUSES BY IMMUNIZATION WITH AGAR GEL PRECIPITATES
M. A. Z. HORNITZKY AND V. E. TAYLOR
A technique for the production of specific antisera to sac brood virus (SBV),chronic bee paralysis virus(CBPV) and Kashmir bee virus (KBV) is described. Antisera suitable for gel-diffusion precipitin tests were prepared against SBV, CBPV and KBV by immunizing rabbits with specific agar gel immune precipitates. These precipitates were produced in gel-diffusion precipitin tests using partially purified viral extracts and reference antisera.
