solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography using silica gel and alumina as the stationary phase. In the second week‚ the students will separate a methylene blue/sodium fluorescein mixture by column chromatography with silica gel as the stationary phase. Part I: Thin Layer Chromatography (TLC) 1. Obtain 2 silica-gel-coated TLC sheets and 1 alumina coated TLC sheet. Measure up 1 cm from the bottom of the TLC strip. Taking care not

as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are negatively charged‚ the gel is placed in a chamber with positively and negatively charge cords on each side of the chamber in order to separate different DNA fragments. The distance that DNA fragment travels depend on its size and

proteins are electrophoresed into a gel‚ as the proteins migrate through the gel they are separated based upon size and charge. Characteristically‚ smaller proteins migrate through the gel faster than larger proteins. Sufficiently separated proteins in an SDS-PAGE can be transferred to a solid membrane (PVDF or Nitrocellulose) for WB analysis. For this procedure‚ an electric current is applied to the gel so that the separated proteins transfer through the gel onto the membrane. To detect the antigen

separate the charges using an electric field. This is done using the gel electrophoresis apparatus where the sample of substance is dispensed into a well in the gel material. The gel is then placed in an electrophoresis chamber‚ which is connected to electricity. When the current is applied‚ the larger molecules move more slowly through the gel and the smaller molecules move faster. The different sized molecules form distinct bands on the gel which will be analysed by scientists. X-ray During the latter

Unit 7 Topic 2 – Reading 7 Mystery of the Stolen Artifacts Federal and state laws protect archaeological remains on public lands. These laws are important for preserving our national and state heritage. Unfortunately‚ there are people who discover these sites‚ excavate the artifacts‚ and sell them for personal gain. These people are called “pot hunters”. This script is a fictional trial of a Mr. Pete Anderson who was accused of illegally taking archeological artifacts from public land. During a

How to Make Gel Candles Gel candle making is a great hobby for all‚ for adults and children (with an adult present at all times). Gel wax isn’t wax at all‚ but a form of mineral oil. It’s easier to work with in many ways than traditional waxes. The clear gel allows you to achieve many interesting looks‚ from floating beads to underwater scenes. First‚ you need to get all the stuff for making gel candle. Material Candle gel Zinc Wicks Fragrance oil Liquid color dye Glass container Stainless

Separation of Proteins and Mass Analysis Using SDS PAGE Biology 00-01L Abstract This experiment consisted of separating proteins into polypeptides using a method called SDS PAGE which is a type of electrophoresis. The polypeptides had different masses‚ so each polypeptide traveled a different distance and this was an essential part of the lab which demonstrated that there exists a relationship between the distance traveled by the protein and the mass of the protein. This relationship was graphed

List all of the ingredients found in an SDS-PAGE gel. Which ingredients are responsible for polymerizing the solution? How does the percentage of acrylamide effect the migration of proteins (ex: 4% gel vs. 18% gel)? The percent acrylamide refers to the size of the pores as percent acrylamide increases the size of the pores decreases

sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Two sets of four protein samples‚ standard bovine serum albumin (BSA)‚ invertase‚ egg albumin‚ and casein‚ were prepared; one set containing β-mercaptoethanol (BME) while the other did not. These were then analyzed through SDS-PAGE with 12.5% resolving gel‚ prepared using 2 M Tris-HCl at pH 8.8 and stacking gel‚ prepared using 0.0625 M Tris-HCl at pH 6.8. Results showed multiple bands located on the upper half of the gel‚ which suggested heterogeneity
