Abstract The experiment‚ entitled Extraction and Characterization of Proteins‚ aims to isolate casein from milk and albumin from egg; to explain the methods employed for protein extraction; to apply spectrophotometric methods in characterizing and quantifying extracted casein and albumin. The experiment was divided into 2 parts; the extraction of Albumin from egg and the determination of protein concentration via the Warburg-Christian method and Bradford Assay method. In the first part‚ egg

The purpose of this experiment is to separate a solution of an acidic and organic compound and purify its respective acidic product through the techniques of an acid base extraction‚ recrystallization‚ and use of Melt Temp (melting point range). The reaction of an unknown acid (3-chlorobenzoic acid) with diethyl and sodium hydroxide was observed‚ and the solution naturally separated into an aqueous and organic solution. The mixture of acid and organic solution was created and then separated through

SOP: Solid phase extraction of cylindrospermopsin in filtered water samples Document identifier: SOP_TOXIC_UDU_05F Prepared by: James S. Metcalf and Geoffrey A. Codd‚ UDU Date: 7 July 2005 1 Introduction In order to determine the concentration of cylindrospermopsin in the extracellular fraction of filtered environmental waters‚ solid phase extraction (SPE) is necessary to concentrate the toxin to concentrations capable of being detected by HPLC. 2 Experimental 2.1 Materials

called extraction. Extraction is a systematic process of separating mixtures of compounds‚ taking advantage of the affinity differences of compounds to separate them (Padias 128-37). This technique recognizes the principle that “like dissolves in like‚” that is‚ polar solutes dissolve in polar solvents and non-polar solutes dissolve in non-polar solvents. Through extension of this principle‚ one can use extraction to separate compounds of a mixture. There are three different methods of extraction; solid-liquid

Berry DNA Extraction Lab I. Problem Statement: Successfully extracting the DNA from strawberries. II. Background info: DNA is the genetic information in organisms that codes for proteins‚ and controls the cells function. The DNA is a double helix molecule that is formed by various nucleotides which include Adenine‚ Thymine‚ Guanine‚ and Cytosine with sugar phosphate. Different organisms can have larger or smaller genes. DNA is also what makes up chromosomes during cell replication. Strawberries

Introduction Extraction is a purification technique used in organic chemistry to separate compounds from a mixture of two or more compounds. There are three different extraction techniques: liquid-liquid extraction‚ solid-liquid extraction and chemically active extraction. All three types of extraction follow the same principle. Organic molecules dissolve in organic solvents and polar molecules dissolve in aqueous solvents. This phenomenon is observed because of the intermolecular forces between

Materials:Benzoic acid‚p-dichlorobenzene‚ether‚10% NaOH‚conc.HCl‚distilled water‚ anhydrous CaCl2. Introduction: Organic compounds in an aqueous mixture can be separated by shaking the aqueous solution with a solvent which is immiscible with water. Extraction involves dissolving either a

Hypothesis: Each step of the process will help in a certain way to extract DNA‚ until we are finally successful in the end. In the wheat germ extraction‚ the ethanol will be able to separate the DNA‚ and it will float between the less dense ethanol and the denser homogenizing mixture. (2) Materials: 1 gram

The purpose of the DNA extraction lab was not only to inform students on how DNA is present in humans and all organisms‚ but to also educate them on how DNA can be extracted using common household materials. Also‚ the lab was very efficient as it introduced the students to extracting their own DNA found on their cheek cells as well as letting them take an observation on how DNA appears or how it is formed. Additionally‚ students were instructed through a very clear and simple procedure‚ which guided
