1 Fragment Library Preparation Using the AB Library Builder System 5500 Series SOLiD Systems QUICK REFERENCE Note: For safety and biohazard guidelines, refer to the Safety section in the Fragment Library Preparation Using the AB Library Builder System: 5500 Series SOLiD Systems User Guide (Part no ). For every chemical, read the SDS and follow the handling instructions. Wear appropriate protective eyewear, clothing, and gloves. Prepare to build the library 1 Quantitate the DNA For accuracy, determine sample DNA concentration using a double-stranded DNA-specific fluorescence assay. Use the Invitrogen Qubit dsdna HS Assay Kit (Invitrogen Part no. Q32851 or Q32854) to measure dsdna concentrations from 10 pg/µl to 100 ng/µl. For samples outside this range, use the Qubit dsdna BR Assay Kit for higher concentrations of DNA (Invitrogen Part no. Q32850 or Q32853) or the Invitrogen Quant-iT PicoGreen dsdna Assay Kit for lower concentrations (Invitrogen Part no. P7589). 2 Shear the DNA with the Covaris S220 System Note: For shearing conditions with the Covaris S2 System, see Shear the DNA with the Covaris S2 System on page 7. a. For each library, mix in a 1.5-mL LoBind Tube: Amount DNA 10 ng 5 µg 1 Low TE Buffer Variable µl Shear Buffer 1.2 µl Total 120 µl b. Prepare the Covaris S2 tank: Fill the tank to level 12. Ensure that the circulated water chiller is set to 2 5 C. Supplement the chiller not the actual water bath with 20% ethylene glycol. Ensure that the water bath temperature is 5 10 C. c. Place a Covaris microtube into the loading station and transfer the mixture to the Covaris microtube.

2 2 Shear the DNA with the Covaris S220 System (continued) d. Shear the DNA using the appropriate program on the Covaris S220 System: IMPORTANT! Ensure that the bath temperature limit is set at 15 C, and keep the bath temperature to 10 C. Condition Setting 3 Set up the AB Library Builder System Instrument for sizeselected or express fragment library preparation Number of cycles 6 Bath temperature 5 C Bath temperature limit 15 C Mode Water quality testing function Frequency sweeping e. Place the Covaris microtube into the loading station, then transfer the 110 µl of sheared DNA to a new 1.5-mL sample tube provided in the Library Builder Fragment Core Kit for 5500 SOLiD. IMPORTANT! If you are preparing barcoded libraries for multiplexed sequencing, for each sequencing run, use at least one of the following full sets of four barcodes: Barcodes 1 4, 5 8, 9 12, 13 16, 17 20, 21 24, 25 28, 29 32, 33 36, 37 40, 41 44, 45 48, 49 52, 53 56, 57 60, 61 64, 65 68, 69 72, 73 76, 77 80, 81 84, 85 88, 89 92, or Use only one of the barcoded-t-0xx adaptors for each ligation reaction, unless < 4 libraries are being barcoded. Use the barcodes according to these conditions: If <4 libraries are prepared for sequencing, then use multiple barcodes per library in equal ratios. For example, for 2 libraries, use 2 barcodes for each library. For 3 libraries, use 4 barcode adaptors for each library for a total of 12 barcodes. If 4 libraries are prepared for sequencing and libraries are split into sets of 4 to use full sets of barcodes, then use one set of barcodes for the remaining libraries (1,2,or 3 libraries). There is no need to use multiple barcodes per library in equal ratios. Off Duty Factor 10% Peak Incident Power Cycles/burst 100 Time 175 Watts 60 seconds a. Thaw the AB Library Builder Cartridges on ice or at room temperature 2 hours or until completely thawed. IMPORTANT!
