To make 1050ml of 1X TAE (1000ml for running and 50 ml for agarose) we will dilute the 50X TAE as follows:
conc. of 50X TAE *volume required = 1X TAE * 1050
therefore volume of 50X TAE required = 1050/50 = 21ml
So 21 ml of 50X TAE will be required and diluted with 1029 ml of distilled water to make it 1X. This will be used as per requirement for agarose and running buffer.
To do electrophoresis, you will need to make a solution called TAE, which is a specific...

You must make a 1x TAE running buffer (40mM tris (pH 7.6), 20mM acetic acid and 1mM EDTA) using tris base (FW= 121.14g/mol), glacial acetic acid (17.4M) and 0.5M EDTA. show how much of each compound you would add to make 1L.
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...
You have a 50X stock of electrophoresis buffer and you need 150ul of 1X. How do you make this happen? For Vs i got 3ul of 50X stock needed to prepare 150 ul of 1X. Then I got 147ul of h2o needed to prep 150ul of 1X. I am wondering if these are correct and if I am using the right wording with my answers? Should i be wording them in a different way? just don't want to get marked...
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...
