- https://www.youtube.com/watch?v=5EGD39ln5LM Describe the process of loading the hemacytometer, being more specific in how the sample should be loaded.The figures below are the results of flow cytometer analysis of a drugs (camptotechin) effect on cells? From what you learned in class about flowcytometry, briefly state what the drug is doing to the cells: HL60 Untreated Camptothecin (45um, 2h) Camptothecin (45um, 4h) 3.36 10 PI (FL2)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
- Blood plasma flows with a rate of 0.4 cm³/s through a tube with a diameter d = 0.18 cm and length 1 = 1.8 m at a temperature of 20°C. The pressure at the tube entrance is P2 = 1.48 x 104 N/m2. If the temperature of the tube and plasma reaches 29°C, what is the tube entrance pressure P2' needed to maintain the flow rate and pressure at the tube exit constant. Consider 120°c = 1.81 mPa·s and n29°c = 1.28 mPa.s.Choose correct option and explain shortly. Question:- Which of the following is the best description of how you can measure white blood cells (WBCs) using the fluorescent light application of a flow cytometer?
