Alkali Scientific CHAPS [3 [(3 Cholamidopropyl) dimethylammonio] 1 propanesulfonate], 100 Grams
CHAPS (3-[(3-Cholamidopropyl)dimethylammonio]propane sulfonate) is a zwitterionic detergent used for membrane protein solubilization, offering mild, efficient protein extraction while preserving protein function. This 100g formulation is ideal for applications in membrane protein studies, including purification, structural analysis, and biochemical assays. CHAPS is often preferred in techniques such as electrophoresis, chromatography, and crystallization due to its ability to stabilize proteins in their native state without disrupting their activity. It is frequently used in laboratory experiments requiring the extraction and solubilization of membrane-bound proteins, enzymes, and cellular components.
