Note: These parameters are intended to be compatible with pre-made 250-mL amounts of [[Griffitts:Common media#LB Broth (1 L)|LB]] agar, such that usually 1 mL of stock solution is diluted into the [[Griffitts:Common media#LB Broth (1 L)|LB]] agar. For liquid [[Griffitts:Common media#LB Broth (1 L)|LB]] (typically 75 mL amounts) 0.3 mL of the stock solution will usually be added. Exception: Gentamycin for ''E. coli''.
