To do electrophoresis, you will need to make a solution called TAE, which is a specific mixture of Tris base, acetic acid, and EDTA. Assuming no errors and no spills, you will need a minimum of 50 ml 1X TAE to make your agarose gel plus 1 liter of 1X TAE for gel running buffer. TAE is normally made as a 50X concentrated stock.
You need to prepare a 0.5% (w/v) agarose gel containing 1X TAE and 1X Gel Red. For a total gel volume of 75ml, calculate the mass of agarose powder and volume of Gel Red concentrate needed. Show your work to be eligible for partial credit. Info about stocks: Agarose stock is powder Gel Red concentrate is 25,000X liquid
Describe how much agarose powder (g), 10X TBE (ml), water (ml) and 20,000X greenglo (ul) you would need to prepare a 4.3% 50ml agarose gel.
You have 50 mL of insulin that is 20X concentrated. You need to dilute this insulin in buffer to a concentration of 2X in final volume of 2 mL to give to a patient. How would you prepare this solution?

QUESTION 7 How many grams of magnesium chloride (x6H2O) are contained in 250 mL of a 0.1 M solution? QUESTION 8 How many grams of sucrose (MW 342) are contained in 250 mL of a 0.1...
Question 23: (10 Marks) a) Given the stock concentration and desired final amount, or desired final concentration, of the following PCR components, calculate the volume of each you would add to a 25 μl PCR reaction mixture. b) You want to analyse the resultant PCR product by agarose electrophoresis. Calculate how much agarose you need to use to make up 50 ml of 1.5 % gel. How much of 5x concentrated loading buffer will you add to load the...
please hlep me answer those three questions asap.
Please ignore question 7.
Question 7 Working with buffers You need 100 ml of 120 mM phosphate buffer and you have two stock solutions from which you can make the buffer; 0.6 M NaH2PO4 (the acid form) and 0.6 M Na2HP04 (the base form). You need to add 3 times more of the base form than the acid form to achieve the desired pH. How will you make this solution? Question 8...
