- In making red blood cell suspension, why do we need to wash red blood cells in saline?Given this, if you used 6g of vitamin Z powder to make 20 ml of solution, what is the % concentration of this solution? (I gave the image since I don't know if that info is needed to solve this question.)It also gives a follow-up, if you can help here too: You work in a lab as a summer student. One of your tasks is to make sure that there is enough cell culture medium containing antibiotics to grow bacteria. One day you realize that there is only 5 ml of 10% Antibiotic stock solution in the freezer. You decide to use it all to prepare the working culture medium with 0.01% antibiotic. In the lab there is plenty of growth medium without antibiotics. (Note: dilution in medium is like dilution in water). You remember the equation to make dilutions of stock solutions. You usually use this formula to calculate the required volume of a stock solution, but you realize it can apply here as well, even though the unknown is the final volume. So, you make that dilution. Given that each bacterial…An iodine solution was sealed inside dialysis tubing, then immersed in a cup of water containing fructose and starch and allowed to react. Recall that iodine solution is red, Iodine + starch = purple. After reaction a) the color outside the dialysis bag would be (red, purple, clear) b) the color inside the bag would be purple (true/false) c) fructose would be present inside the dialysis bag (true/false)
- briefly explain the principle behind this technique; gel-filtration chromatographyGel-filtration chromatography separates molecules according to their size . Smaller molecules diffuse faster in solution than larger ones, yet smaller molecules migrate more slowly through a gel- filtration column than larger ones. explain this paradox. What should happen at very rapid flow rates?What is the purpose of Deproteinization and why is it needed before chemical analysis of certain constituents in the blood?
- With the aid of a diagram, explain the principles of gel filtration chromatography.Why is potassium solution injection lethal?Discuss in chemical detail the mechanism of action (how it works) of IMAC. Compare and contrast gel filtration chromotography with IMAC. Discuss the pros and cons for each technique. Why would a scientist prefer one technique over another? In what situations would one technique be more viable than the other?
- Choose the best combination of depyrogenation methods: 0.45 um filtration + 0.22 µm filtration OUV+0.45 um filtration 0.22 µm filtration + UV treatment 0.45 um filtration + distillation 0.22 µm filtration + distillationExplain how gel filtration chromatography works. What type of gel will you used when the protein size is 2500 Da? Explain.Porous dialysis tubing is used to create a "model cell" containing glucose and albumin, a protein. This "cell" is placed into a beaker containing water and Biuret reagent. Initially the "cell" is colorless and the beaker is light blue. At the end of the experiment, the "cell" is light purple and the beaker is still light blue. What accounts for the color change observed? O Biuret reagent entered the cell and reacted with protein. Glucose exited the cell and reacted with Biuret reagent. Biuret reagent entered the cell and reacted with glucose. O Protein exited the cell and reacted with Biuret reagent.
