General Description

CAPS (3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate) is a zwitterionic detergent commonly used in biological research and molecular biology applications. It is known for its ability to solubilize and stabilize membrane proteins, making it a valuable tool for protein purification and membrane protein analysis. CAPS has a molecular weight of 483.62 g/mol and a high solubility in water, making it easy to work with in laboratory settings. It is a mild detergent that does not denature proteins, making it suitable for use in protein extraction and other biochemical assays. Additionally, CAPS is often used as a buffer component in electrophoresis and chromatography techniques, as well as in cell culture and immunohistochemistry protocols.
