NONIDET® P-40 SUBSTITUTE Grade:REAGENT GRADE CAS Number: 9016-45-9Synonym(s): None Molecular Weight: N/AMolecular Formula: N/A Storage Condition: ROOM TEMPERATURE CodeSizePriceQuantity E109-50ML E109-100ML E109-500ML Non-ionic – containing no charge (polyoxyethylenes or alkyl glucosides). Non-ionic detergents are suited for solubilizing membrane proteins without altering biological activity. These non-denaturing, gentler detergents are ideal for studying the conformation and function of proteins because they keep secondary and tertiary structure intact. Non-ionic detergents efficiently separate hydrophilic proteins from membrane spanning, hydrophobic proteins.
