A student needed to prepare 500mL of 1X TAE buffer to run a QC gel. The stock solution in the lab is 5X TAE. What volumes of sto

Xelga [282]

Answer:

you need 100ml of 5X TAE and 400ml of water.

Step-by-step explanation:

You need to use a rule of three:

$C_1V_1=C_2V_2$

where:

$\left \{ {{C_1= 5X} \atop {C_2=1X}} \right.$

and

$\left \{ {{V_1 = V_{TAE}} \atop {V_2=500ml}} \right.$

Therefore:

$V_{TAE} = \frac{V_2*C_2}{C_1}$

$V_{TAE} = 100ml$

Then just rest the TAE volume to the final Volume and you get the amount of water that you need to reduce the concentration.
