Rifampicin resisistance in E.coli cells was studied.
By Anonymous on 12/03/2018
Assay Type: In Vitro
Species: Human

In our lab rifampicin resisistance in E.coli cells was studied.To assess the level of antibiotic resistance, the minimum inhibitory concentration (MICs) of rifampicin in the non-mutated strain and mutated strain were compared.
