PermeaPad Plate

1. Ideal for artificial membrane permeability tests without using Caco-2 cells. 2. Good reproducibility and wide applicability. 3. 96-well format.

PermeaPad Plate uses a unique lamination technology to pack a phospholipid membrane with a cellulose film membrane, creating an artificial membrane (PermeaPad). PermeaPad is used in artificial membrane permeability tests for early-stage drug screening. It can be stored at room temperature and does not require any pre-treatment, making it easy to handle. Due to its three-layer structure of <cellulose>-<phospholipid>-<cellulose>, PermeaPad is resistant to solvents and surfactants, allowing for permeability testing. Furthermore, it maintains stable permeability across a wide pH range (pH 1 to 10), making it less susceptible to pH gradients and enabling tests under various conditions. The PermeaPad Plate is in a 96-well plate format. The drugs added to the insert plate (or bottom plate) permeate to the bottom plate (or insert plate), and the concentration changes are analyzed using HPLC or LC-MS. The bottom plate can be set in a standard microplate reader, providing excellent versatility.

Permeapad Plate Drug Membrane Permeability Test

Drug membrane permeability tests using artificial membranes without Caco-2 cells, with a unique lamination technology to create multilayers of lipids and films.

Evaluation of Drug Permeability from Cell Membranes Using Artificial Membranes In the development of new drugs, the examination of the pharmacological properties and toxicity of compounds, along with the study of absorption characteristics from intestinal membranes, is considered one of the important factors. The evaluation of absorption characteristics is generally conducted using Caco-2 cell tests. To perform Caco-2 tests, cell culture on the membrane of test well plates is required, but this cultivation demands significant time and effort. Issues may arise with the reproducibility of permeability tests due to the heterogeneity of the culture. The Permeapad Plate, which laminates phospholipids with a special film, serves as an alternative method for compounds where membrane permeability is rate-limiting in Caco-2 tests. Since the phospholipids are laminated with a film, they can be stored at room temperature and used immediately. The homogeneous film allows for high measurement reproducibility.
