HIS-selective medium is a type cell culture medium that lacks the amino acid histidine. It can be used with bacteria reliant on the expression of a gene encoding proteins involved in histidine expression in order to survive.[1] Only bacteria expressing such genes (such as hisB in Escherichia coli and HIS3 in Saccharomyces cerevisiae) will survive on these media.
