ABI 3100 Performance with Various STR Typing Systems


Participants: John M. Butler, Margaret C. Kline, Richard Schoske, and Peter M. Vallone


Project Timeframe: April 2001 to June 2003



Purpose: To examine the ability of the ABI 3100 to reliably type short tandem repeat (STR) commercial kits and in-house assays.


Progress: We have had an ABI 3100 16-capillary system in our laboratory since April 2001 and have successfully analyzed a variety of STR typing kits including Promega’s PowerPlex® 16 and Applied Biosystems’ IdentifilerTM 16plex kits. A second ABI 3100 was purchased in June 2002. These commercial kits and new research multiplex assays we have developed in-house use a variety of fluorescent dye combinations with both 4-dye and 5-dye chemistries. We have generated DNA fragment analysis matrices on the 3100 using various combinations of the following dyes: 5FAM, JOE, NED, ROX, 6FAM, HEX, FL, TMR, CXR, VIC, PET, and LIZ. We have also evaluated performance of samples on both the ABI 310 (single capillary) and ABI 3100 (16-capillary array) instruments. Sensitivity and resolution were also explored on the ABI 3100 platform. We determined that the 16-capillary ABI 3100 using POP-6 polymer worked well and produced a throughput of approximately ten times that of the single capillary ABI 310 using POP-4 polymer. We introduced the ABI 3100 into routine use within our research laboratory.
