The GS FLX Titanium Sequencing Kits XLR70 and XL+ plus PicoTiterPlate Kit support various bead loading region configurations. The size and number of PicoTiterPlate (PTP) regions to use depend on the sequencing throughput requirements of the experiment, in total bases or total reads. To determine the proper gasket size, proceed as follows:

Use Table 1 to identify the size and number of bead loading regions best suited to yield the sequencing throughput for your DNA library sample. The throughput presented in Table 1 is typical for good 200 cycle (XLR70 kit) or 400 cycle (XL+ kit) sequencing runs performed using good quality shotgun libraries and for amplicon libraries with fragments up to 700 bp. For example, column 4 of Table 1 shows the expected throughput of a full sequencing Run carried out with the longest run script available for this kit (200 cycles, generating an average read length of 350 to 450 nt or 400 cycles, generating reads up to 1 kbp in length), with all regions loaded.
