Preservation of lyophilization of anaplasmosis capillary tube-agglutination test antigen.
An antigen for anaplasmosis capillary tube agglutination test was lyophilized, using different stabilizers. The lyophilized and control (suspension) antigens were maintained at 4, 18, and 37 C and tested for reactivity with known positive and negative sera once every 7 days for a period of 28 days and then once every 2 weeks for a grand total of 154 days. Both the lyophilized and control antigens retained their antigenicities during the entire test period.
