The enzyme is a biological catalyst that is crucial for the biological reactions inside the body of living organisms. There are different perspectives to study and understand the enzyme. We can look into their structures (specifically the protein structure since the major component of enzymes are ...
Thus, allowing the DNA to be selectively bonded with the positively charged ions of the added ethanol and salt solution. b. The molecular advantages of the column method that involve the use of Qiagen spin columns is that there are many more steps in the purification process that the ...
2KHSO4 + ethanol → K2SO4↓ + H2SO4 The aqueous solution of Potassium bisulfate is acidic, with a pH of approximately 1.4 for a 1 mol/L solution. In some cases, the solution of Potassium bisulfate can be used instead of a 39.0-42.0% sulfuric acid solution. For example, distilling...

Mixed systems consisting of triethanolamine-ethanol-isopropyl myristate have been shown to improve skin penetration of acidic drugs. TEA is also used as an active ingredient in ear drops for the treatment of embedded earwax. In addition, 1% TEA as a capping agent helps to maintain the s...
It is soluble in dimethyl sulfoxide, dimethyl formamide, glacial acetic acid and chloroform, slightly soluble in ethanol, sparingly soluble in water, and practically insoluble in ether. At a pH of 0.6-5.8, levofloxacin water solubility is constant at approximately 100 pg/mL (sparingly soluble). ...
is then washed in an ethanol solution, air-dried and resuspended in the final sample buffer. figure 1. conventional phenol-chloroform phase separation demonstrating the three layers. the upper aqueous phase (rna) and the inter- and organic phase (dna and protein). subsequently, rna is extracted...
