Abstract
The most widely used technique for penicillin assay is the so-called cylinder-plate method of Abraham et al. (1941), with various modifications such as those described by Foster and Woodruff (1944) and by Schmidt and Moyer (1944). In using this method for large numbers of assays we have found it advantageous from the standpoint of time involved and reproducibility of the method to use a 4 1/2 x 11 1/2 inch, rectangular, culture plate on which 40 cylinders can be placed.
