Optimizes agar precipitation conditions for Marek's disease serology; leaves open diagnostic adoption pending field validation in poultry.
The study identified the optimal in vitro conditions for agar precipitation between Marek's disease antigen and chicken serum antibodies.
Okazaki et al. (1970) studied Marek's disease. Various agar concentrations, NaCl concentration, buffers, pH, and incubation time/temperature was evaluated on Optimum conditions for precipitation in agar. The optimum conditions for precipitation in agar between Marek's disease antigen and antibody were 1% special agar-Noble, 8% NaCl, NaK phosphate buffer, pH 7.4, and incubation at 37 C for 72 hours.
