Cholera and other diarrheal diseases cause nearly 2 billion cases of diarrhea annually. Cholera toxin and other bacterial toxins cause the intestine to secrete fluid into the lumen of the gut, depleting the extracellular fluid (ECF) volume. If fluid loss is not matched with fluid intake (law of mass balance), the result is severe dehydration, circulatory collapse, and even death. Drinking a rehydration solution is the most rapid and effective way to replace the large volumes of water lost by...

Lab 9 – Molecular Biology In this lab, you will prepare an agarose gel and use gel electrophoresis to compare the size of 2 dye molecules Methyl orange and Ponceau G. You will also analyze an “unknown” sample that contains a mixture of two dyes. Dye molecules with lower molecular weight or greater electrical charge will migrate faster through the gel, than dye molecules with greater molecular weights or lesser electrical charge. Materials: Mini gel electrophoresis chamber 6 Tooth comb...
