not to damage the white‚ powdery stationary phase‚ use a #2 pencil to draw a line across the width of the strip. Carefully mark two evenly spaced spots along the line to delineate where to spot the dye solution. 2. The TLC strip can now be spotted. Use the capillary tube to apply two dots of the dye onto the TLC strip as in the figure 1 below. 3. Transfer enough solvent into a 200 mL beaker to achieve a level of about 0.5 cm deep. Cover the developing chamber with a glass lid or with a watch

Fund raising to meet the high costs of campaigning is the most important hurdle for any candidate for public office (Dye‚ 286). Lifting the cap on amount donors can contribute in a congressional election cycle will make fund raising much easier for candidates‚ but not all candidates will benefit equally. “Look at whoever is most powerful in congress right now and you

ABSTRACT At First my heartiest air towards to ALLAH‚ then thanks to our course teacher Mr.Rajib saha who give me chance to work regarding Detergent. A detergent is an agent used for cleaning. Detergents are synthetic surfactants‚ which is produced from petrochemicals rather than fatty acids and oils. They are very effective in hard‚ soft as well as salt water. Detergents are the salts of long chain of hydrocarbons such as alkyl sulphates. A detergent has several advantages over soaps in which we

Title: Bradford Assay: Creating a Standard Curve and Determining Unknown Protein Concentrations Introduction: In biochemistry the ability to determine the quantity of a certain substance in a solution is extremely important. Often protein concentration within a biological organism is essential in determining the function or condition of that organism. If the protein concentration in an environment is increased or decreased it can have detrimental side effects. If there is a decrease in hemoglobin

TITLE: The Amount of Protein in Chicken Tissues over Cooked Various Periods of Time. ABSTRACT: In this lab‚ we are using a BioRad protein assay dye to determine the concentration of protein in our chicken. The dye binds to the amino acid residues‚ which allow us to find the concentration of protein (BioRad Protein Assay for Tissues). Our hypothesis was the longer chicken is cooked the less protein is available. To test our hypothesis‚ we made samples using our chicken and distilled water to determine
