7. Sample Preparation Compute Options Sample preparation compute options: • Volume to Use • # of SMRT® Cells • Loading Titration Tool tips are available for most of the options and input/output parameters in single sample view
8. Enter Sample Information – Sample Name, Volume to Use, DNA Concentration and Insert Size 1. Enter the Sample Name 2. Enter the Volume of SMRTbell™ Library volume you plan to use 3. Enter the Concentration (ng/μL) of SMRTbell Template before annealing 4. Enter Insert Size (bp)
9. Enter Sample Information – Details 5. Select Magnetic Beads (Yes/No) 6. Select Binding Kit 7. Select Preparation Protocol : • Select ‘Small scale’ for DNA SMRTbell™ template concentrations less than 62 nM • Conversion Calculator provides (ng/µL ↔ nM) 6. DNA Control Complex (Yes/No) 7. Complex Reuse (Yes/No) • For diffusion loading only 8. Non-Standard Reaction (Yes/No) • Use this option if library sample is limiting
10. Optional Parameter Settings 9. Use Default values for these options unless preparing for a custom sequencing reaction • Concentration On Plate • DNA Control Complex: Template Ratio • Polymerase:Template Ratio
11. Setup Primer Annealing Reaction 10. Dilute the sequencing primer from 5000 nM to 1000 nM in Elution Buffer provided by PacBio 11. Prepare annealing reaction using the instructions provided by the calculator
12. Dilute Polymerase for Binding Reaction 12. Dilute the DNA polymerase to the required working concentration (50 nM)
13. Bind Polymerase to Templates 13. Two options : • Use the entire annealed SMRTbell™ template • Enter the # of SMRT® Cells you plan to use
14. Using Binding Complex for Sequencing • Two steps • Dilute complex per the desired loading concentration. Add DNA control if required • Bind complex to MagBead for loading
15. Diluting the DNA Control Dilute the DNA Control Complex stock solution using the Bead Binding Buffer provided in the MagBead Binding Kit to prepare an intermediate working solution
16. Diluting the Sample Complex Dilute the polymerase-bound DNA sample using the Bead Binding Buffer and add the diluted DNA Control Complex from the previous step
17. Binding Complex to MagBead Prepare MagBead and bind diluted complex to washed MagBead. After binding, wash and load the sample on to instrument
18. Loading Titration Compute Option 18 • Enter the desired titration experiment concentrations for up to four SMRT® Cells • For titrations, start with the default loading recommendation in the optional section. Include titration points for 1/2x and 2x of the default loading recommendation.
19. Loading Titration Reaction Setup 19 • Loading Titration section shows how to set up the required sequencing reactions at each loading concentration

27. PacBio® Recommends the Following: • When scaling up your sequencing runs, it is highly recommended to perform loading titrations – Use the default loading recommendation as one of your titration points – Avoid under-loading or over-loading of your samples • Use DNA Controls – Helps isolate issues associated with the samples and the instrument – Use the RS Dashboard to view DNA Control Metrics • Sequence samples within three days of binding 27
