Application
Activated thiol Sepharose™ 4B is used in protein chromatography, affinity chromatography and activated/functionalized matrices. Activated thiol Sepharose™ 4B has been used to provide the first report of the isolation of aminopeptidase H from a reptile. Activated thiol Sepharose™ 4B has also been used to purify and characterize a neuropeptide-inactivating peptidase.
Physical form
Lyophilized powder stabilized with lactose and dextran

A ubiquitin hydrolase that removes ubiquitin from a multi-ubiquitinated protein has been purified 600-fold from Saccharomyces cerevisiae. Four different ubiquitin-protein conjugates were assayed as substrates during the purification procedure. Enzymic activities that removed ubiquitin from ubiquitinated histone H2A, a ubiquitin-ubiquitin
The non-specific binding of undesired ligands to a target is the primary factor limiting the enrichment of tight-binding ligands in affinity selection. Solution-phase non-specific affinity is determined by the free-energy of ligand binding to a single target. However, the solid-phase
DNA photolyase purified from baker's yeast by affinity chromatography on UV-irradiated DNA noncovalently bound to cellulose and by chromatography on activated thiol-Sepharose 4B yields a single protein band having a molecular weight of 51 000 when analyzed by sodium dodecyl
Aminopeptidase H was isolated and purified from fresh skeletal muscle of the lizard Agama stellio stellio by ammonium sulfate fractionation and successive chromatographies on DEAE-cellulose, Ultrogel AcA-34, activated thiol-Sepharose 4B, phenyl-Sepharose CL-4B, and DEAE-cellulose again. This is the first report
Glutathione peroxidase (GPx) activity was detected in the ascite fluid of rats injected intraperitoneally with 2.5% heat-denatured casein solution. Activity in the ascite fluid increased with time after the injection of casein, and reached a maximum at 24 h. The
