Imipenem (hydrate) Artikelnummer: Cay16039-100
Imipenem is an intravenous beta-lactam antibiotic effective against a wide range of Gram-positive and Gram-negative bacteria (MICs range from 0.5-2 µg/ml for E. cloacae and P. aeruginosa), including several multi-drug resistant bacterial species. Imipenem acts by interfering with bacterial cell wall synthesis.

Leupeptin (Ac-Leu-Leu-Arginal-hemisulfate) Artikelnummer: 12136.100
Leupeptin, also known as N-acetyl-L-leucyl-L-leucyl-L-argininal, is a naturally occurring protease inhibitor that can inhibit cysteine, serine and threonine peptidases. It is often used during in vitro experiments when a specific enzymatic reaction is being studied. When cells are lysed for these studies, proteases,...

Sodium Dodecyl Sulfate (SDS), pure Artikelnummer: 04051.1
SDS is commonly used in the preparation of proteins for electrophoresis in SDS-PAGE. This compound works by disrupting non-covalent bonds in proteins, denaturing them and causing the proteins to lose their natural conformation. The new negative charge is significantly larger than the original charge of that protein....
