of the GFP protein. This indicates that the molecule responsible for the observed green trait was protein. The transformation efficiency was found to be 793.75 transformants per microgram. The protein was filtered out of the cell and column chromatography was used as a means to isolate the protein by taking advantage of its hydrophobic properties. This was performed by washing the column containing the GFP protein amongst other proteins with buffers varying in salt concentrations. As expected

Title: Candy Chromatography Background Information and Research: Paper Chromatogrpahy is a analytical method that is used for seperating and identifying mixtures of color. There are two stages‚ the stationary phase and the mobile phase. The first is for a solid and the second for a liquid or gas. -Reference http://www.chemguide.co.uk/analysis/chromatography/paper.html Purpose: To see how paper chromatography works. Materials: · Candy with a colored coating‚ like Skittles® or M&Ms® (4 different

antioxidant. Lycopene is found in various fruits and vegetables. The purpose of this experiment is the isolation of Lycopene from tomato paste. This is done using liquid/solid extraction and chromatography. Once the Lycopene is isolated‚ IR spectroscopy will determine its percentage actually obtained by chromatography. Procedure: A massed sample of 1.012g of tomato paste was placed in a 125mL Erlenmeyer flask. To the flask‚ 5mL of 50:50 hexane-acetone was added into the flask. After the 50:50

Asymmetric Epoxidation of Dihydronaphthalene with a Synthesized Jacobsen’s Catalyst Justin Lindsey 12/08/96 Chem 250 GG Professor Tim Hoyt TA: Andrea Egans Abstract. 1‚2 diaminocyclohexane was reacted with L-(+)-tartaric acid to yield (R‚R)-1‚2-diaminocyclohexane mono-(+)-tartrate salt. The tartrate salt was then reacted with potassium carbonate and 3‚5-di-tert-butylsalicylaldehyde to yield (R‚R)-N‚N’-Bis(3‚5-di-tert-butylsalicylidene)-1‚2-cyclohexanediamine‚ which was then reacted with Mn(OAc)2*4H2O
