Geneticin 25 10 Water (H2O) -20 ~ 4 ̊C
Gentamycin 10 15 Water (H2O) -20 ̊C
Hygromycin 10 10 Water (H2O) -20 ̊C
Kanamicin 50 10 Water (H2O) -20 ~ 4 ̊C
Kasugamycin 10 1000 Water (H2O) -20 ̊C
Nalidixic acid 5 15 Water (H2O) at pH 11 15 ̊C
Neomycin 10 100 Water (H2O) -20 ̊C
Rifampicin 34 150 Methanol -20 ̊C
Spectinomycin 10 100 Water (H2O) -20 ̊C
Streptomicin 50 10 Water (H2O) -20 ̊C
