To prepare 300ml of 1x TAE buffer solution from a 50x stock solution, calculate the volume of stock solution needed using the formula C1V1=C2V2. Plugging in 50x for C1, 1x for C2, 300ml for V2 gives a value of 6ml for V1, the volume of 50x stock solution required. Take 6ml of the 50x TAE stock solution and dilute it with deionized water to a total volume of 300ml to obtain the desired 1x TAE buffer solution.
