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

dependent variable upon the x variable as time. The oscilloscope has the internal device called a sweep oscillator‚ which moves the electron beam across the screen at a constant rate. Therefore‚ the oscillator plots y (voltage) versus x (time). PROCEDURE: Put the 1.5 Volt battery across the y-input. Put the switch on Direct Current. Then measure the number of divisions that the dot jumps. Reverse the polarity of the battery and measure the number of divisions again. Connect an audio oscillator

‘old’ words and the 60 ‘new’ words. ‘Old’ words referring to words seen before (first phase) and ‘new’ referring to words that haven’t been seen. The false alarm rate was the number of times the word was called ‘old’ when it was actually ‘new’. Procedure Participants completed a practice trial (60trials) on the university computer‚ which was identical to the study phase. In the memory phase when participants saw ‘old’ words‚ being the targets‚ they pressed (/) and ‘new’ words (z). Each word was

A. ENG237-02: Transients in RC and RL Circuits 0. Introduction The objective of this experiment is to study the DC transient behaviors of RC and RL circuits. This experiment has divided into 6 parts: 1. Charging curve from measured data ( R = 10M Ω and C = 4 mF ) 2. Draw the charging curve by the graphical method 3. Discharging curve from measured data ( R = 5M Ω and C = 4 mF ) 4. Draw the discharging curve by the graphical method 5. Display of the charging and discharging

Planarian Lab Report Hanna Klein Bishop Fenwick High School Planarian Lab Report Introduction Planarian worms are free-living flatworms that are not parasitic. Planarians have a three-cavity digestive system. Planarians are usually either carnivorous or scavengers. Planarians may eat other living‚ as well as dead‚ invertebrates‚ detritus or decaying organic matter. Planarians do not realize that are eating a lot‚ and can over eat resulting in death. Most planarians are freshwater forms that can

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

Proteomics is the study of proteomes‚ which are groups of proteins in living systems. It is used to examine when and where proteins are being expressed‚ rate of degradation‚ modifications‚ how they interact with other proteins and more. The goal in this lab was to determine the similarities and differences in muscle proteins among 5 species of fish using SDS-PAGE and Western blotting. First‚ proteins are separated based on size. Second‚ antibodies are used to detect the protein of interest. Lastly‚ a substrate
