Kaari Liisi Linask National Heart, Lung, and Blood Institute U. S. Department of Health and Human Services National Institutes of Health National Heart, Lung, and Blood Institute Genotyping Automation Using Multiprobe II HT, Caliper AMS 90 SE, and Filemaker 7/22/2003

Procedure Overview 1. Sample lysis 2. Filemaker generation of CSV data files for robotics software 3. Master mix preparation 4. Multiprobe PCR setup 5. Thermal-Cycling 6. Caliper electrophoresis

Tissue Lysis • 2 mm tail biopsies are lysed in a Nunc 96 well plate with 100µL lysis buffer containing 0. 2 mg/m. L Proteinase K • Incubation @ 55°C with shaking for ~4 hours on Thermomixer R with PCR plate adapter • Heat inactivation of Proteinase K @ 95°C for 10 minutes on PTC 200 Thermocycler

Filemaker Genotyping Database § Five linked files: 1. 2. 3. 4. 5. § DNAList. fp 5 Master. Mix. fp 5 Multiprobe. fp 5 PCRList. fp 5 Post. Mix. fp 5 Convert Required Sample info into a listing of PCRs in comma-separated value format (. csv) that the Multiprobe and Caliper software can access.

Required Sample Information from 7/8/2003 DNA Plate 1. Sample or Tag. ID 2. Plate. ID (Date) 3. Row (A-H) 4. Column (1 -12) 5. Genotypes To Be Determined (Up to 3)

DNAList. fp 5 Scripts 1. Import DNA Plate Records 2. Find DNA Plate Records (up to 4) 3. Assign DNA Plate# (DNA 1, DNA 2, DNA 3, DNA 4) 4. Generate Multiprobe Table

DNAList. fp 5 and PCRList. fp 5 files • Converts the Row (A-H) and Column (1 -12) to a Well # with Multiprobe Numbering by column • Looks up and records the PCR required for each PCR TBD based on the PCRList. fp 5

DNAList. fp 5 with samples from 7/8/2003 displayed

Plate Numbering Conversions ¬ Multiprobe: Numbered by column Well# = Row + (8 X Column) - 8 ¬ Caliper: Numbered by row Well# = (12 X Row) + Column -12

Generate Multiprobe Table Script • Deletes previous sample records from the “Multiprobe. fp 5” file. • Goes through each found record’s PCR fields (1 A-3 B). If there is a reaction specified, a record is added to the “Multiprobe. fp 5” file for each instance with Multiprobe well #, PCR master mix required, DNA Tag. ID, Plate#, and Plate. ID recorded for each PCR reaction. • Adds (-) controls for each PCR required. • Adds `H 2 O` wells to fill up the last partially utilized row of the PCR plate (required for Caliper AMS 90 SE). • Finds, sorts, and numbers the needed PCR master mixes required including `H 2 O` in the “Master. Mix. fp 5” file. • Sorts by PCR required and Tag. ID (ascending ASCII) • Assigns PCR plate (currently up to 2), well row, and well column numbers arranged for Caliper AMS 90 SE processing in rows.
