Roxanne, Alix

-Restriction Digesting RS3 and RS6 again with XbaI and SpeI at 37.0 C for 2 hours.

-Attempting a new method of Gel Extraction (or rather an old method, new to us). Freeze 'n Squeeze.

Protocol: Freeze 'n Squeeze

-Run the sample you wish to extract on a TAE-Agarose Gel

-Cut out the band you wish to purify

-Incubate in 1 gel volume 0.3 M NaCOOH at room temperature for 30 minutes.

-Make your own spin column from a small microfuge tube with a hole cut out of the bottom, 
stuffed with glass wool. This tube should be inserted inside a 1.5 mL microfuge tube.

-Transfer the solution to the spin column.

-Freeze the tube in liquid Nitrogen for 1 minute, then spin at full speed for 15 minutes.
 
-Precipitate the DNA in Ethanol. Remove the supernatant.

-Wash in 75% Ethanol. Remove as much ethanol as possible.

-Centrifige for 5 minutes then, remove the rest of the ethanol.

-Let pellet to air dry for 10 minutes, this allows all ethanol to evaporate off.

-Resuspend in TE Buffer, 10 uL.

-Quantify either by Gel or UV Spec.

-Proceed with ligation.
