Agarose is used widely in gel electrophoresis because it gels at a lower temperature‚ does not contain the inhibitors of virus growth frequently present in agar‚ and has more uniform

Gel Electrophoresis Adventure Intro The final goal of this lab was to successfully measure the size of different samples of DNA by placing each sample into a well in agarose gel and running a current through a charged chamber. The DNA samples will move through the gel towards the positive charge. Ideally‚ the DNA will move and create and sequence of smallest to largest. This lab exposes us to DNA technology. Backround Gel electrophoresis is used to separate macromolecules like DNA or RNA by size or

Gel electrophoresis is a routine laboratory procedure in biochemical studies that takes advantage of a protein’s amphoteric nature to determine its molecular weight and charge by running the sample through a gel matrix under the influence of an electrically charged field. A popular example of gel electrophoresis is Sodium dodecyl sulfate-polyacrylamide electrophoresis or SDS- PAGE which has been used in this experiment to supposedly determine albumin and casein’s molecular weights respectively. The

BI338 Lab 1 Measuring the Success of Pisum sativum leaf cell fractionation: SDS-Polyacrylamide Gel Electrophoresis and Western Blot Analysis Introduction In order to evaluate the success of cellular fractionation‚ there are various methods that can be implemented that target specific proteins and/or receptors specific to particular organelles. SDS-PAGE (sodium dedocyl sulfate- polyachrylamide gel electrophoresis) is a technique used to separate proteins based on their mass. As different proteins

to the sol-gel transformation by proposing that the micellar unit of the gel state is identical with that in the sol. According to these authors: "All that is necessary is to assume that the particles become stuck together or oriented into loose aggregates‚ which may be chance granules or‚ more probably threads." This conception is based on a study of sodium oleate‚ for which they found that in spite of the enormous change in viscosity involved in the change from sol to gel‚ such properties

Carbopol 940 could yield clear gel with desired rheological property. Carbopol 940 was selected as a gelling agent based on preliminary experiments and previous reports due to its widespread use in pharmaceutical formulations and fast dispersion in water (Sahoo et al.‚ 2014; Sharma and Bedi‚ 2014; Pillai et al.‚ 2015). Moreover‚ it is speculated that Carbopol with low concentration can be safe for nasal administration (Khan et al.‚ 2010). Carbopol is known to have mucoadhesive properties. It
