應用

Calcium chloride hexahydrate has been used as a test compound for measuring the overall activity of low-molecular-weight antioxidants in biological samples by using ′total antioxidative capacity′ inhibition assay.[1]

生化/生理作用

Calcium chloride act as precipitants during protein crystallization process.[2] It also enhances the competence of Escherichia coli cells in transformation experiments. It strengthen β-lactoglobulin gels by forming crossbridges.[3]

Escherichia coli cells are 4--6 times more transformable and 20--30 times more competent after 24 h incubation in cold calcium chloride than immediately after calcium chloride treatment. With 24-h-old competent cells we obtained routinely 2 . 10(7) transformants per microgram

Aerobic metabolism requires a complex antioxidative system to balance reactive oxygen species (ROS). When in excess, ROS disrupt cellular activities and molecular structures. Owing to the variety of ROS, there are different antioxidative activities that require various tests for their

Protein crystallization is a major bottleneck in protein X-ray crystallography, the workhorse of most structural proteomics projects. Because the principles that govern protein crystallization are too poorly understood to allow them to be used in a strongly predictive sense, the

Obtaining maximal sensitivity of nano UHPLC-MS/MS methods is primordial to quantify picomolar concentrations of neuropeptides in microdialysis samples. Since aspecific adsorption of peptides to Eppendorf tubes, pipette tips and UHPLC vials is detrimental for method sensitivity, a strategy is presented

Azo-bonded prodrugs of 5-aminosalicylic acid (mesalazine)-sulfasalazine, balsalazide, and olsalazine, which are used in the treatment of ulcerative colitis, rely on colonic bacteria to cleave the azo bond and liberate the active drug in the large intestine. The aim of this
