Electrophoresis of Amino Acids Introduction: Electrophoresis is a separation technique based on the movement of charged ions under the influence of an electrical field. This technique is primarily used for the separation of amino acids and peptides on the basis of their charge. All amino acids contain ionizable groups that cause the amino acids‚ in solution‚ to act as charged polyelectrolytes that can migrate in an electric field. The amino acids with a net positive charge will migrate toward

Agarose Gel Electophoresis of DNA Topoisomers Introduction DNA can exist as different isomers that change the confirmation of the DNA’s structure. DNA can be in a linear confirmation this is a relaxed confirmation as the DNA can rotate about its axis unconstrained. It can also exist as a nicked circle this is also a relaxed confirmation as the DNA strands can again rotate freely with respect to one another. Covalently closed circular DNA or cccDNA exists as a supercoil this is because the covalent

Sodium hydroxide‚ also known as caustic soda‚[2][3] or lye‚ is an inorganic compound with the chemical formula NaOH (also written as NaHO). It is a white solid‚ and is a highly caustic metallic base and alkali salt. It is available in pellets‚ flakes‚ granules‚ and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water‚ ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries

Determination of Sulfate by Gravimetry Jose Luis E. De Guzman University of Santo Tomas‚ Sampaloc‚ Manila The determination of the percentage of sulfate in a sample is done as an instrument of learning a quantitative method of analysis‚ i.e.‚ of the gravimetric analysis. This type of analysis‚ which makes use of the weight of the samples was used for the experiment and required the precipitation of our analyte‚ SO4-2‚ and its filtration as a BaSO4 precipitate so as for weighing it. The weight

Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314

Chapter Location Strategies Discussion Questions 1. FedEx’s key location concept is the central hub concept‚ with Memphis selected for several reasons‚ including its being in the middle of the country and having very few hours of bad weather closures. 2. The major reason for U.S. firms to locate overseas is often lower labor costs‚ but as this chapter‚ Chapter 2‚ and Supplement 11 suggest‚ there are a number of considerations. 3. The major reason foreign firms build in the U.S. is to satisfy
