iPLEX® Pro Sample ID Panel* A highly accurate, rapid research method for sample identification and quantification February 2013 * The iPLEX® Pro Sample ID Panel is for Research Use Only. Not for use in diagnostic procedures Agenda Applications & Use Content Biochemistry Data Analysis with Live Demo Getting Started Q&A 2 February 27, 2013 . The Importance of Sample Identification in Research Studies Laboratory procedures are not 100% foolproof Samples can be mislabeled or contaminated Leads to repeat experiments, time delays, and/or retraction of publications Challenge of the research community is to ensure correct samples are used and reported in research studies 3 February 27, 2013 . Applications for Sample Identification 4 Cell line authentication Chain of Custody events Sample replicate pairing Tumor vs. non-tumor pairing Sample QC Library barcoding February 27, 2013 . Use Case Scenarios Application Use Case Example(s) Outcome Cell Line Authentication Verify identity (One cell line) Cell Line1 = Cell Line1 Expected Match Cell Line1 ≠ Cell Line1 Unexpected Mismatch Verify identity (Multiple cell lines) Cell Line1 = Cell Line2 Unexpected Match Cell Line1 ≠ Cell Line2 Expected Mismatch Our software provides easy summary reports 5 February 27, 2013 . Use Case Scenarios Application Use Case Example(s) Outcome Tumor vs. NonTumor Single patient (One tumor) T1 = N 1 Expected Match T1 ≠ N 1 Unexpected Mismatch Single patient (Multiple tumors) T1A = N 1 = T1B Expected Match T1 = N 1 ≠ T1B Unexpected Mismatch Our software provides easy summary reports 6 February 27, 2013 . SNP Genotyping as a Method for Sample Identification Key publications provided the basis for the iPLEX® Pro Sample ID Panel* * The iPLEX® Pro Sample ID Panel is for Research Use Only. Not for use in diagnostic procedures 7 February 27, 2013 . Benefits of Sample Identification using the MassARRAY® System For use with cell lines, FFPE tissue, blood, NGS libraries Comprehensive SNP coverage for sample identification and QC High-throughput panel with minimal input DNA and reagent usage Automated reports for convenient, rapid sample comparisons within a single plate or against an entire database Relevant for tracking and qualifying samples in your MassARRAY® or NGS workflow * The MassARRAY System is for Research Use Only. Not for use in diagnostic procedures 8 February 27, 2013 . iPLEX® Pro Sample ID Panel* Comprehensive Coverage 44 SNP loci across genome High overall heterozygosity to adjust for population stratification (45-55%) Not in exon or variable regions High overlap with SNP for ID and original ABS Sample ID panels Low random match for error and high confidence Not intended for forensic, parentage, ethnic identification, or monozygotic twins. * The iPLEX® Pro Sample ID Panel is for Research Use Only. Not for use in diagnostic procedures 9 February 27, 2013 . Quality Control Check Provided for Each Sample Not enough SNPs for an accurate match or mismatch (N = 30) Not enough amplifiable copies (N < 500, 1 ng) Key for qualifying formalin-fixed paraffin embedded tissue Don’t waste sample, time, or reagents that would not be suitable for a MassARRAY®* or NGS run Quickly pass or fail samples to reduce time & material costs * The MassARRAY System is for Research Use Only. Not for use in diagnostic procedures 10 February 27, 2013 . iPLEX® Pro Sample ID Panel* Biochemistry Robust biochemistry PCR amplification followed by iPLEX® Pro primer extension Convenient assay Single multiplexed well with 52 markers (44 SNPs, 3 Gender, 5 Copy Number) Minimal DNA required (10 ng) Low running cost per sample *The iPLEX Pro Sample ID Panel is for Research Use only. Not for use in diagnostics procedures. 11 February 27, 2013 . Use Case Scenarios Tumor to Normal Comparisons Advantages of Upfront QC Quantify amplifiable copies postextraction Ensure normal to tumor samples are correctly paired Pass or fail samples prior to library prep, sequencing, or MassARRAY®* panels “Molecular barcode” can be stored in database for future reference Non-tumor Tumor Extract DNA Sample ID (Primary QC) MassARRAY® Panel (or NGS) Tumor to Normal Comparison * The MassARRAY System is for Research Use Only. Not for use in diagnostic procedures 12 February 27, 2013 . Use Case Scenarios NGS Library Tracking Sample ID with Libraries 13 A rapid technical QC method for tracking samples Ensure interesting results are not an artifact of sample mixup Sequence analysis can be conducted in parallel Requires ~10 µl library to obtain a molecular barcode February 27, 2013 Normal Tumor NGS Library Prep Sequence Sample ID Sequence Normal to Tumor Comparison . Sample ID Barcoding NGS Libraries vs. Sample Identification Illumina Barcoding Multiple samples are pooled together for a sequencing run Barcode tags are used to differentiate reads for each sample Sequenom iPLEX Pro Sample ID Panel* Use in parallel to ensure the right samples are contained within the library pool Expected match or mismatch using Sample ID signature for each barcoded sample ? Combine NGS barcoding with Sample ID *The iPLEX Pro Sample ID Panel is for Research Use only. Not for use in diagnostics procedures. 14 February 27, 2013 . iPLEX® Pro Sample ID Panel Data Analysis Perfect match: +10 for non-tumor vs. non-tumor; +5 non-tumor vs. tumor Penalty scores for any mismatches of individual SNPs Non-tumor vs. tumor comparison ignores any normal heterozygote SNP calls for LOH Quickly assess samples for all 44 SNPs at a glance *iPLEX Pro Sample ID Panel is for Research Use only. Not for use in diagnostics procedures. 15 February 27, 2013 . iPLEX® Pro Sample ID Panel* Software and Database Compare samples within selected plates and against a database Compare samples only within a selected set of plates LIVE DEMO *iPLEX Pro Sample ID Panel is for Research Use only.
