The data produced from these experiments are much less variable If your cell populations are homogeneous. Liquid cultures or confluent growths on strong medium are very best suited for reproducible tradition preparing. The situations of organism planning and storage need to be standardized to the neutralizer evaluation and should mirror the ailments with the antimicrobial assay.

However, in most cases, preprinted sorts are in various copies that has a 2nd or third duplicate in a central file. Some corporations use log-books for recording knowledge. These logbooks also needs to be reviewed.
