An in vitro intestinal drug disposition device (1) comprises a donor chamber (2) for a donor solution and having a bottom end (18) and a top end (19). The device (1) also comprises a receiver chamber (3) for an absorption solution and an absorption membrane (4) arranged in between and separating the chambers (2, 3). A first side (5) of the absorption membrane (4) is to be in contact with the donor solution and a second side (6) of the absorption membrane (4) is to be in contact with the absorption solution. A ratio of an internal volume of the donor chamber (2) to an area of the first membrane side (5) is equal to or smaller than 3 ml/cm.sup.2. A cross-sectional area of the donor chamber (2) at the bottom end (18) is larger than a cross-sectional area of the donor chamber (2) at the top end (19).

The present invention provides: an assay method that uses a compound represented by formula (I) as a fluorescent probe molecule and that is for detecting the lipid peroxidation suppression activity of a test compound; an assay kit that uses the assay method; a screening method that uses the assay method; and a pharmaceutical composition that is for the treatment, etc. of diseases (such as age-related macular degeneration) that are induced by lipid peroxidation reactions. ##STR00001##

Provided is a method for isolating a ureteric bud tip cell from cells, a tissue, or an organoid comprising the ureteric bud tip cell, comprising the following steps of contacting the cells, tissue, or organoid comprising the ureteric bud tip cell with a very low density lipoprotein receptor (VLDL-R) binding agent, and isolating the ureteric bud tip cell using the binding agent as an indicator.

A method of spectrometric analysis comprises obtaining one or more sample spectra for an aerosol, smoke or vapour sample. The one or more sample spectra are subjected to pre-processing and then multivariate and/or library based analysis so as to classify the aerosol, smoke or vapour sample. The results of the analysis are used for various surgical or non-surgical applications.
