STR Amplification Set-up Tool

§  Select the AmpFℓSTR® Kit(s) for downstream analysis from the STR Kit Library

§  Each kit template is pre-populated with default reaction set-up parameters and dilution scheme (customizable)

§  Software determines sample dilution and volume added to the STR reaction based on Quantifiler® results

Page 25: Improving your Casework Workflow with a Next Generation Quantification Solution

25 Life Technologies™ |

Lab Configurable Software Solutions

§  Default Quantifiler ® and AmpFℓSTR® Templates can be optimized based on your workflow – simply add/import samples

§  Default Analysis Settings can be defined based on your SOP

−  Choose which Data Quality Flags you wish to use as well as threshold values

−  Dilution Calculations – define overage, min/maximum volumes, dilution factors

−  STR Reaction Setup – target input amounts, reaction component and sample volumes.

§  Data Display and Export – define Table, Plot and Plate views and Export formats
