Resazurin sodium (Resazurin sodium salt) salt is a blue non-fluorescent dye,is widely used as a metabolic indicator for living cells

Resazurin 抑制包括对多种抗生素产生耐药性的 N. gonorrhoeae 分离株在内的广泛 N. gonorrhoeae 分离株的生长[1]。

在体内，resazurin 并未限制小鼠在阴道感染后与 N. gonorrhoeae 的定植。resazurin 在体内无效很可能是因为它与血清白蛋白的相互作用，这完全消减了其抗菌活性[1]。

Overnight broth cultures were used to inoculate FB containing resazurin sodium salt, resorufin sodium salt , resorufin acetate [Marker Gene Technologies, Eugene, OR; dissolved in dimethyl sulfoxide (DMSO)], resorufin butyrate or resorufin pentyl ether . In select experiments, FB was also supplemented with 3 g/dL bovine serum albumin (BSA) . Immediately following inoculation and 24 h later, cultures were serially diluted and were plated onto chocolate II agar. Plates were incubated at 37 °C in 5% CO2 and individual colonies were enumerated. The limit of detection was 100 CFU/mL[1].
