You are given a cell stock A. You make a 1:100 dilution and load 10µL diluted sample to a hemocytometer. After counting all 5 "one millimeter squares" you get an average of 60 cells. Then you decide to do a 1:1000 dilution to verify your counting. How many cells do you expect to get in average with 1:1000 dilution? Select one: a. b. 12 O c. 30 d. 20 To do a 1:100 serial dilution. This is what you will do: Select one: You take 1uL of original cell stock and add into 99 uL of 1XPBS to make a 1:100 dilution a. b. You take 90uL of cell stock and add that into a tube containing 10uL of 1x PBS. C. You take 99uL of cell stock and add that into a tube containing 10uL of 1XPBS. d. You take 10uL of original cell stock and add into 90 uL of 1x PBS to make a 1:10 dilution. You thoroughly mix the 1:10 dilution tube. Then you take 10uL out from 1:10 tube and add it into a new tube containing 90uL of 1×PBS.

You are given a cell stock A. You make a 1:100 dilution and load 10uL diluted sample to a hemocytometer. After counting all 5 "one millimeter squares" you have 51 cells in average. (Please write down each step)T 1. What is the cell concentration of this diluted sample? 2. What is the cell concentration of original cell stock ? 3. If the original stock A has a total volume of 5mL, what is total number of cells in the A? 4. You decide to do a 1:1000 dilution to verify your counting. After loading and counting, you find out that you have 20 cells in average in each square. Do you think the new concentration is consistent with your previous result? If not, list all the possible errors that can cause this inconsistency. MacBook Air

A 5mL sample diluted 1:1 with trypan blue is counted using a hemocytometer. A total of 325 viable cells and 52 dead cells were counted in the four corner square and the big central square of the meter. What is the total number of dead cells per mL of the sample?
Dr. Riggs took 1ml of whole mouse blood and added it to 10ml of PBS. You next take 0.5 mL of Dr. Riggs's sample from step 1 and add it to 9.5 mL of PBS. You load your hemacytometer with the dilution you made in step 2, look at it under the microscope, but there are still too many cells to count. You now take 0.2mL of sample from step 2 and add it to 5ml of PBS. Using a hemacytometer, you load your sample and count the following number of red blood cells in 1 chamber (5 squares): chamber 1 = 25, 25, 30, 20, 30 If this mouse has 2 mL of blood in it’s body, how many red blood cells does it have?

You collected 1000 mL of river water from the streamrunning through campus. You prepared dilutions of the water as follows:Tube A. 0.5 mL of river water + 99.5 mL of sterile waterTube B. 1 mL from Tube A + 9 mL of sterile waterTube C. 1 mL from Tube B + 9 mL of sterile waterTube D. 1 mL from Tube C + 9 mL of sterile waterYou then plated 0.1 mL of each dilution onto each of three MacConkey agarplates. (MacConkey agar is type of selective, differential medium. It inhibitsthe growth of Gram-positive microorganisms and non-enteric Gram-negative bacteria. Among the bacteria not inhibited by the medium,lactose-fermenting bacteria form pink colonies and bacteria that do notferment lactose form colorless colonies.) After incubation, the colonieswere too numerous to count on the plates prepared from dilutions A, B, andC. For the plates prepared from dilution D you counted the followingnumbers of colonies:Plate 1: 157 pink colonies and 62 colorless coloniesPlate 2: 167 pink colonies and 67…
