For the OPS straws, with a black marker write the cell line and passage number on the side and draw a line around the top of each straw (this allows for sight of the straw when encased in the outer straw). 2. Prepare one vitrification 4-well plate to vitrify up to 8 straws (containing 4–6 hESC colony fragments each) from a single cell line. (a) To well #1 and well #2 prepare “Bench medium” (20 % FCS in DMEM-HEPES) by addition of 800 μL DMEMHEPES and 200 μL FCS. (b) To well #3 prepare Vitrification Solution 1 (10 % DMSO and 10 % ethylene glycol in Bench medium) by addition of 600 μL DMEM-HEPES, 200 μL FCS, 100 μL DMSO, and 100 μL ethylene glycol.

Spin down the plates at 600 Â g for 2 min. 3. Load 10 μL per well using multichannel pipette onto the 384well or the 96-well plate using fresh tips each time as shown below. For 96-well plates, one well is sufficient to load one row of the plate (Fig. 2). 4. Seal the plate with the MicroAmp® Optical Adhesive Film, and centrifuge it at 600 Â g for 2 min. 5. Place the plate in a compatible RT-PCR instrument equipped with the appropriate thermal block (Note 8). 34 Jeffrey Fergus et al.
