    The objectives of this experiment were to investigate the activity of enzymes‚ components that influence the enzyme’s activity‚ identify an unknown phosphatase‚ influence of inhibitors‚ and determine if inhibition is competitive or noncompetitive. A spectrophotometer evaluated the measurement of color change over a period time due to product being formed. Determining unknown phosphatase and effects from different inhibitors were determined by varying the pH and substrate concentrations. The unknown

    system to isolate the alum. 2 Al(s) + 2 KOH + 22 H2O + 4 H2SO4 → 2 KAl(SO4)2●12H2O(s) + 3 H2(g) Its composition was analyzed using two precipitation tests and two flame tests. Three methods for growing crystals were then set up for observation next lab. Theoretical yield and percent yield: The theoretical yield for alum was 4.55g and the percent yield was 139%. The percent yield was above 100% because the alum was saturated with ethanol and water. KOH test: The KOH test identified the presence of

    Materials & Methods Synthesis Procedure of PDA@MT Polydopamine is synthesized through covalent polymerization similar to melanin biosynthesis‚ with DA oxidized to dopamine quinone‚ then further oxidized to DHI‚ which undergoes deprotonation and cross-linking via Michael addition to form PDA. A solution was prepared to synthesize PDA by mixing 90 mL of water‚ 40 mL of ethanol‚ and 3 mL of ammonia solution in a 300 mL beaker. After stirring for 30 minutes at 37°C‚ a solution of 500 mg of DA dissolved

    The experiment consists of 5 steps—Inoculation‚ fermentation‚ cell lysis‚ inclusion body solubilization‚ and peptide purification. In the first two steps‚ E coli with Snake 6 peptides is cultivated. Ultraviolet–visible spectroscopy (UV-vis) is used to quantify bacteria through detection of their optical density (O.D.). After reaching a certain concentration in the fermentation batch‚ inclusion bodies (IBs) are extracted from these E coli by adding Bugbuster lysis solution and lysozyme. Polyacrylamide

    Determining Allele Frequencies of the PV92 Alu Element using DNA Isolated from Human Cheek Cells and PCR Amplification Background Alu elements are the most abundant repetitive elements in the human genome that have mobilized throughout primate genomes by retrotransposition over the past 65 million years ago from a 5’ to 3’ fusion of the 7SL RNA gene‚ to reach the present number of more than one million copies. Over the last few years‚ several lines of evidence demonstrated that these elements
