Assay—
Assay preparation 1
(where it is packaged for dispensing)—Constitute Neomycin for Injection as directed in the labeling. Withdraw all of the withdrawable contents, using a suitable hypodermic needle and syringe, and dilute quantitatively with Buffer No. 3 to obtain a solution having a convenient concentration.
Assay preparation 2
(where it is packaged for dispensing and where the labeling states the quantity of neomycin in a given volume of constituted solution)—Constitute Neomycin for Injection as directed in the labeling. Dilute an accurately measured volume of the constituted solution quantitatively with Buffer No. 3 to obtain a solution having a convenient concentration.
Procedure—
Proceed as directed for neomycin under Antibiotics—Microbial Assays 81, using an accurately measured volume of Assay preparation diluted quantitatively and stepwise with Buffer No. 3 to yield a Test Dilution having a concentration assumed to be equal to the median dose level of the Standard.
