A method for screening an active ingredient of a saltiness enhancer, the screening method including the following steps: (i) a step for determining whether a test substance is a compound capable of promoting functional expression of the TMC4 gene or TMC4 protein; and (ii) a step for selecting, as an active ingredient of a saltiness enhancer, a test substance that has been determined in step (i) to be a compound capable of promoting functional expression of the TMC4 gene or TMC4 protein.

The invention relates to an in vitro method for determining the adsorbing capacity of an adsorbent having limited solubility, such as a bile acid sequestrant, under conditions simulating the mammalian gastrointestinal tract. The method is particularly useful for studying the release profiles of controlled release formulations comprising adsorbents having limited solubility.

A method of using the transverse relaxation rate (R.sub.2) of solvent NMR signal to detect filling errors of an alum-containing product in real-time in-line during manufacturing, for example during a fill-finish unit operation. This technique can be used for quality control in vaccine manufacturing to ensure the delivery of the correct concentration of alum-containing product to the product container such as a vial or pre-filled syringe.

The present invention relates to a method for product identification comprising subjecting a sample to cyclic voltammetry, wherein the sample is subjected to a plurality of voltammetric cycles to obtain a data set for each cycle and wherein the data sets comprise data points; and comparing the data set for each cycle with a data set for a corresponding cycle of at least one known product to determine whether the sample is the known product. The present invention further relates to a method for determining a profile for a known product, which may be used in determining the identity of a sample.
