How would you prepare 1.5 ml of a 1:1000 dilution of the CB2 primary antibody (1° Ab CB2) in 1% milk solution if 1.5 μl is provided in a tube. Specifically, how much 1% Milk in DPBS will you add to the tube?
Answer:
Here milk is the diluent,
Dilution factor= (aliquot vol + diluent vol)/aliquot vol
1000= (1.5uL+ diluent vol)/1.5uL
(1000 x 1.5)- 1.5= diluent volume
diluent volume= 1498.5uL
Add 1498.5uL of 1% milk to the 1.5uL antibody provided to you.

Dilution, help?? 5. You add 25uls of antibody to 475 uls of water - what dilution did you just make? 6. (3 pts) To obtain a countable plate to quantify your bacterial sample you first dilute the sample 1/500 in Tube 1 and then make a 1/25 dilution of this sample in Tube 2. If the total volume for your dilutions is 1 ml: a. How much water should be in Tube 1 and how much of your initial bacterial...
D O BLO 1151CI UURI. 5) How much primary antibody do you need to add to 10mL of milk (Blocking) solution to get a 1:1000 concentration? There needs to be 10ul of the primary antibodies added to 10ml af mill to the
how would you prepare a 1:1000 dilution of a standard solution
How would you prepare a 1/100 dilution (of a concentrated stock solution) in a final vol of 100 ml? 2.5 L? 87 ml? (ie how much diluent and how much of your concentrated stock)?
Your cell suspension is 6.3 x 10^8 cells /mL. Explain how to prepare a tube of 1 mL with cells at 2 x 10^5 cells/mL. Pipetting less than 1 μL is hard to do accurately. Do a dilution if less than 1μL After dilution,Now that you have your tube of 1 mL with cells at 2 x 10^5/mL, explain how to add 10^4 cells to each of 10 wells. Do you have enough cells?
Dilution Practice Problem #5 You are given the following bacterial dilution scheme: ml 1 ml 1 ml 1 ml 1 ml CODILE 9ml 9ml 9ml 0.1 ml 0.1 ml colonies) (colonies colonies) Individual tube dilutions: BCD Dilution Factor: Total tube dilutions) IDE AB Plated dilution factor 1. Which plate is the countable plate? (30-300 countable range) 2. Calculate the titer of the original culture in cfu/ml.
Explain how you would make a 1/1000 dilution of a bacterial suspension if you only had 3 ml aliquots of BHI broth (diluent) available. What size pipetman will you need to use to make this dilution?
please show work so: 1 ml stock 10 ml final -0.5 mL of stock -5 ml final volume While I have used 1:10 as a standard the same rules apply for all dilution factors. Try these problems: x 0.5 X0.5 1. You need to make a 1:25 dilution factor. If you final volume is 25 mL this means that you need_ _mL of stock and mL of solvent to make your final volume of 25 mL. 2. If you needed...
b. 1 ml 1ml 「-I Final dilution 4(1 point) This represents a serial dilution to determine viable bacterial counts. Indicate the final dilutions in each of the two tubes. Note that two different volumes of the cells intube #2 are plated onto agar plates A and B. Indicate the dilution factor that will be used to report the original cell concentration on a per mL basis. 1 ml 1 ml Final dilution in Tube #1 = Final dilution in Tube...
