OIL PURIFICATION A SCIENCE INVESTIGATORY PROJECT CHAPTER I Background of the Study INTRODUCTION Oil used in cooking foods is commonly derived from vegetables. Cooking oil is commonly used for frying and oil used for frying is usually thrown away. The recycling of cooking oil also provides a form of revenue for restaurants‚ which are sometimes compensated by cooking oil recyclers for their used deep fryer oil. Cooking oil recycling also results in less used oil being disposed

system for the construction of enhancer trap lines in Arabidopsis. (Lovell‚ 2013) GAL4-GFP enhancer trap system It’s a system for GAL4 targeted gene expression. An enhancer trap vector bearing a modified GAL4-VP16 gene was inserted randomly into the Arabidopsis genome by Agro bacterium mediated transformation. Cell specific activation of the GAL4-VP16 gene by cellular enhancer results in activation of a linked GFP gene‚ allowing simple characterization of expression patterns. Targeted expression of

Method The ester was prepared by the lab assistant in the fume cupboard by reacting 3-methylbutan-1-ol (iso-pentanol‚ 25mL)‚ and acetic anhydride (24mL plus 3 drops of concentrated sulfuric acid). A strong exothermic reaction occurs. Once the reaction mixture is cooled in the fume cupboard

Purification of Infliximab[3] begins at Stage 1 with the filtration of the harvest material using a spin filter. The harvest is then clarified and undergoes 3 main chromatographic steps. Firstly‚ at Stage 2‚ the direct protein capture by Protein A affinity chromatography helps to remove a large majority of the impurities whicn include viruses and media components. At Stage 3‚ prior to cation exchange chromatography‚ the purified material in the eluted stream is then subjected to freezing‚ thawing

Experiment 55: A Separation and Purification Scheme The final lab report/procedure write-up will consist of the following: Report guide: 1. List the names‚ structures‚ and amounts of each compound in your mixture. 2. Draw a flow chart (like pg 687 in PLKE) showing how you separated and isolated your two compounds. Be sure to include the structures of the compounds at each step. 3. Write a procedure. This should include exactly how you performed your separation. It should have enough
