Preparation Method
: The antiserum is prepared by hyperimmunizing goats with highly purified dog IgM; antiserum is delipidated and made specific by solid-phase absorption. The resulting antiserum is dialyzed into 0.02M sodium phosphate, 0.14M sodium chloride, pH 7.3, with 0.05% sodium azide, adjusted to standard titer, filtered through a 0.22 µm filter, vialed and lyophilized.
