- We’re back in the lab having fun! Our current experiment calls for us to treat our cells with THC (yeet!, delta 8 from hemp of course lol) and the final concentration of 15 µM once it has been added to the cells. We need to treat 10 mL of cells, and we don't want our treatment volume to be more than 10 µL per 1 mL of cells. What concentration should we make our stock solution? (I submitted this question before and got an answer of 150 µM and that was incorrect)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…1) If you have 2.5g of hydrocortisone POWDER, how many grams of a 0.05% ointment can be compounded? 2) How many mL of a 0.45% saline solution can be made with 6750 mg of sodium chloride? 3) Your pharmacy receives an order to compound 120 g of a 1.25% cream. How many mg of drug are required to compound this order? 4) Is it possible to make 1200 mL of a 30% dextrose solution with only 75 g of dextrose? 5) You are asked to compound a 15% zinc oxide cream. How many grams of this cream can you make using 30,000mg of zinc oxide? 6) Using 45g of acetic acid, how many mL of a 20% acetic acid solution can be made? 7) Calculate the percent strength of a solution when 8 g of drug is dissolved in 400 mL of solution. 8) Calculate the percent strength of a solution when 2.5 g of drug is dissolved in 750 mL of solution. 9) Calculate the percent strength of a solution when 5000 mg of drug is dissolved in 500 mL of solution.
- I am trying to figure out how much albumin and globulin are in our egg white sample. The egg white is 38.51g. It was diluted with 200 mL of water, and I was told to find the dilution factor. We were told that 38.5g is equal to 1mL of water. The dilution factor I calculated was 38.51mL (egg white)/238.51mL (total volume)= 1:6 dilution factor. We then took 40mL of the diluted sample and centrifuged it to separate the albumin and globulin. Using a given standard curve, we calculated the concentrations of albumin and globulin for each tube with different amounts of each protein. There were other solutions added to each tube for the spectrophotometer, but each one had a total volume of 5mL including the albumin and globulin. To find mg protein in the tube, do I multiply the concentration by the total volume in the tube or by the mL of protein added to each tube? To calculate the amount of each protein in the egg white, I multiplied each concentration in the table by the dilution factor,…Why does water separate out from a gel after freezing?Your supervisor gave you a 5% saline (NaCl) solution. You need to make 100ml of 1.0% saline solution. How much 5% saline would you take to complete the task?
- Do you think standard plate counts are very accurate? Why or why not? When doing serial dilutions, why is it necessary to plate more than one dilution? You left a carton of orange juice on your counter for 3 days. When you taste it, it is very bubbly (as though it was carbonated), and it tastes more bitter than usual. (Note: acids taste bitter). What do you think could have happened? (Note: you can’t just say that bacteria grew—you must explain how the growth of the bacteria resulted in the changes in the orange juice.) Based on what you now know about the presence of bacteria on chicken and beef, why is it a good idea to use separate chopping boards for meat and for vegetables? Please help me thank youAfter blood collection, the red cells are separated from the serum to be used for the preparation of the stock solution. How is it done? For the serial dilution, your stock solution must have a concentration of 3.5 mg/mL. How much diluent must be added to the 5.3 mg/mL red cell to prepare the stock solution? Show pertinent solution/s. What is the appropriate diluent used for the preparation of the red cell suspension?You have determined that a cell suspension contains 1 x 103 cells/mL. That cell suspension was prepared by adding 1 ml of a more concentrated cell suspension to 999 mL of phosphate buffered saline. What is the concentration of cells in the original cell suspension?
- What is the difference between normal and reverse phase chromatography?Which reagent removes contaminant proteins from DNA solution? Sodium dodecyl sulfate (SDS) Sodium citrate saline buffer Cold absolute ethanol O HCI4 mL of 10% TCA solution was added to 1 mL of serum and after mixing, it was waited for two minutes and filtered through non-phosphorus filter paper. 1 mL of the filtrate was taken and 13 mL of distilled water, 4 mL of sulfomolybdic acid and 2 mL of dilute SnCl2 solution were added and mixed, and after waiting for 15 minutes, the absorbances of the obtained solutions against pure water at 520 nm were read. If the function of the calibration graph obtained with 0.5-2.5 mg/mL standard phosphorus solutions is y= 0.245x + 0.107 and the absorbance value of the serum sample is 0.109, what is the amount of phosphorus in the sample?
