Abstract
Summary
The effectiveness of NaN3 in concentrations of 0.1% and 0.05% as a preservative for anti-Rh agglutinating serums has been investigated. It was found that in these concentrations the agent was markedly bacteriostatic, but had no apparent effect on the titer or avidity of the antiserum. Anti-Rh serum deliberately contaminated with common bacteria but not preserved with NaN3 rapidly lost potency when stored at 37°C.
