Enzymes in Laundry Detergents

Introduction In today's laundry detergents, enzymes such as proteases and amylases are some of the active ingredients. In the U.S., about 50% of liquid detergents, 25% of powder detergents, and almost all powdered bleach additives now contain enzymes to help break down stains that are otherwise hard to remove with conventional surfactants alone.

Detergents for Cell Lysis and Protein Extraction | Thermo ...

Detergents are amphipathic molecules, meaning they contain both a nonpolar "tail" having aliphatic or aromatic character and a polar "head". Ionic character of the polar head group forms the basis for broad classification of detergents; they may be ionic (charged, either anionic or cationic), nonionic (uncharged), or zwitterionic (having both positively and negatively charged groups but with a ...

DNA Extraction Lab - Towson University

Detergents and soaps breakdown cell membranes and proteins so that the DNA can be released. Protein enzymes or proteases, like those in contact lens cleaner or “Ultra” forms of laundry detergent, can be used to further this process of breaking down proteins. Once the DNA fragments are released into solution, the DNA can be spooled
