Figure 1: Affinity chromatography of fumarase with the Ni2+-NTA-agarose column. Extract (9.9 mL) containing yeast (3.76g) in extraction buffer containing 0.1% Igapel CA-630 and protease inhibitors were pumped through Ni2+-NTA-agarose column. Fractions were collected by 1.5 mL portions by use of wash buffer (20.0 mL)‚ imidazole elution buffer (26.3 mL)‚ and wash buffer (10.0 mL)‚ again. Absorption readings were taken for all fractions with a Cary50 set at 280nm. The fumarase activity was determined

Title: Thin-Layer Chromatography Objectives: Part1: 1. To learn the technique of TLC and the visualization of colourless components. 2. To identify an unknown drug by a TLC comparison with standard compounds. Part 2: To learn the separation technique by using Thin Layer Chromatography plate in separating a mixture of compounds into individual pure compound by using Spinach Leaf. Introduction: (i) General Concepts Chromatography is a common and powerful method used to separate and analyze complex

pressure (Pc) is a pressure above which the substance can no longer exist as a gas no matter how high the temperature is raised. A supercritical fluid is any substance that is above its Tc & Pc [critical point]. CRITICAL POINT In other words‚ when a substance is above Tc & Pc‚ it exists in a single phase which is neither liquid nor gas; this is a supercritical fluid. 4 Example : CO2 usually behaves as a gas in air at STP or as a solid called dry ice when frozen. If the temperature &

Tittle: Separation of leaves pigment. Introduction The photosynthetic pigment is used to absorb light during the process of photosynthesis. There are five pigments usually found in spinach leaves: Carotene (yellow)‚ Phaeophytin (yellow-grey)‚ Xanthophyll (yellow-brown)‚ Chlorophyll a (blue-green)‚ Chlorophyll b(green). Photosynthetic pigment is located in the chloroplast of the leaf. The function of chlorophyll a and chlorophyll b is to trap red and blue violet light when they carry out photosynthesis

Separation of the Components of Vodka using Fractional Distillation Fractional distillation‚ also known as rectification or fractionation‚ is common in industrial usage‚ not only for simple mixtures of two components (such as alcohol and water in fermentation products‚ or oxygen and nitrogen in liquid air) but also for highly complex mixtures such as those found in coal tar and petroleum. The purpose of fractional distillation is to separate a mixture of two miscible liquids (liquids that mix
