They were found to be soluble in Tris buffer of low ionic strength along with a number of as yet unidentified proteins. The implications of this observation on the in vitro proteolysis of salt-soluble MBP were examined. 展开 DOI: 10.1007/978-1-4615-5405-9_187 ...
I have an HCl amine salt and I am trying to methylate the amine, however since it is present as the HCl salt I am having difficulty performing the reaction so I was wondering what is the best method to convert the salt to the free amine so I can carry out my reaction??Thanks a ...
1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide HCl is Commonly known as EDAC, EDC or EDCI, this carbodiimide HCl salt is used as a coupling reagent in the synthesis of amides and carboxylic esters. EDAC is highly soluble in water and in most organic solvents, it can be employed in liquid an...
A well completion and workover method wherein a subterranean formation is contacted with a high density, nondamaging treating fluid which comprises a saturated, aqueous saline solution with at least one water soluble salt that is substantially insoluble in the saturated saline solution. The water ...
Salt and pepper, to taste Instructions: Heat olive oil in a large pot over medium heat. Add onion and garlic, cooking until softened. Stir in the smoked paprika and chili flakes, cooking for 1 minute until fragrant. Add the kale, white beans, and vegetable broth. Bring to a boil, the...
The MTT assay is based on the capacity of mitochondrial enzymes of viable cells to reduce MTT, a yellow soluble salt, to a purple-blue insoluble formazan precipitate. This conversion is quantified using a spectrophotometer at a wavelength of 570 nm. ...
Since chlorine is a derivative of salt and sodium, sometimes it cannot be easily dissolved. When the chlorination process is done, it goes to a special process where radiation is involved. With the help of Ultraviolet rays, water is then radiated to ensure that the remaining chlori...
For affinity-precipitation, proteins (~5 mg) were solubilized from five dishes (round, 10 cm in diameter) of the heavy- and light-labeled cells, respectively, with a lysis buffer containing 2% dodecyl maltoside in 150 mM NaCl and 20 mM Tris-HCl (pH 7.4). The solubilized proteins...
