Evaluation of liquid nitrogen storage for preservation of group A streptococcal M protein-sensitized sheep red blood cells
Appl Microbiol.
1970 Sep.
Abstract
Streptococcal M protein-sensitized sheep red blood cells stored in liquid nitrogen showed insignificant change in titer when tested against homologous antisera over a 6-month period. This method eliminates much of the preparation time required for the passive hemagglutination procedure and increases the reproducibility of the test.
