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 that responds with an enzyme is used to view the antibody/protein complex. Within a muscle tissue‚ there could be as many as 19 different protein types and the largest

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Muscle and Nerve Preparation Preparation of Ringer ’s solution Dissolve 6.5 g of sodium chloride (NaCl)‚ 0.14 g of potassium chloride (KCl)‚ and 0.20 g of sodium bicarbonate (NaHCO3) in 800 mL of distilled water. Also‚ dissolve 0.16 g of hydrated calcium chloride (CaCl2.2H2O) and 0.39 g of hydrated magnesium sulfate (MgSO4.7H2O) in 100 mL of distilled water. Add the 100 mL cautiously to the 800 mL‚ stirring vigorously. Then make the final volume equal to 1 liter by adding more distilled water

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

junior scientist for MitoSciences. I have been given the task of organizing and analyzing the results from a prior experiment my supervisor Ms. Ehnar Jiy conducted. In this lab‚ i wanted to know if more active cells in our bodies require more energy. I started of by taking five samples of three different types of cell (skin cell‚ muscle cell and lung cell) and counted the mitochondria present in each by viewing the cells under a powerful optical microscope. According to my data‚ i found out that my hypothesis
