    Studies
    1) NARG 2010 STUDY NOW OPEN Contact Sridar Chittur (schittur@albany.edu) to participate in this study The Nucleic Acids Research group (NARG) of the ABRF invites you to participate in a collaborative study focused on the evaluation of optimal priming strategies for cDNA synthesis in quantitative PCR experiments. Additionally we aim to evaluate the impact of RNA integrity on these experiments. This study offers each participant an opportunity to benchmark their current lab techniques and contribute to the shared knowledge of the real-time qPCR community at large

    4) NARG 2007 Real-Time PCR Survey

    The Nucleic Acid Research Group (NARG) of the Association of Biomolecular Resource Facilities (ABRF) invites anyone who uses “Real-Time” quantitative PCR (qPCR) to participate in our on-line survey. The aim of the survey is to determine the current status of real-time PCR technology in laboratories around the world, particularly core laboratories. Your answers will help us "take the pulse" of the real-time qPCR community. Submissions are anonymous and results will be freely available via a "web poster". This survey will be “open” until February 2, 2007. Results will be presented at the ABRF 2007 annual meeting in Tampa Bay, FL, Mar 31-Apr 3, 2007 and will be available "on line" by May 1, 2007. We think it will be worth your time to participate in this study.

    5) NARG 2006 Study: Priming Strategies for Real-time RT-PCR

    The purpose of this study is to provide an opportunity for participating laboratories to gain crucial information about the variability of the RT-step of the qPCR assay and about the comparability of qPCR results obtained using different cDNA priming strategies. In addition, the study will act as an audit for participating laboratories, who will be able to compare the results from their protocols, techniques and equipment with those from other laboratories around the world. The study is open for those who use Taqman® probe-based or SYBR Green I-based assay systems. Deadline for sample submission is Dec. 15, 2005. Data will be presented at the ABRF 2006 annual meeting in Long Beach, CA, February 11 - 14, 2006. We think it will be worth your time to participate in this study.

    6) NARG 2005 Study: Validation of Your Reverse Transcription Real-Time PCR Technique

    The purpose of this study is to give investigators an opportunity to test their reverse transcription real-time PCR technique and to gather information about the performance of various platforms, variations due to reagents and how people analyze their data. The study is open for those who use both Taqman® type systems and SYBRgreen systems. Deadline for sample submission is Dec. 15, 2004. A poster containing a table showing (anonymously) how the individual participants fared in their assay efforts will be posted on this page. Data will be presented at the ABRF 2005 annual meeting in Savannah, GA, March 5 - March 8, 2005.

    7) NARG 2003/2004 Real-Time PCR Survey

    This survey was designed to determine the current status of real-time PCR technology in laboratories around the world, especially Core laboratories. The answers allowed us to "take the pulse" of the real-time PCR community. The survey was open from November 15, 2003 until January 15, 2004. Submissions were anonymous . Results were presented at the ABRF 2004 annual meeting in Portland, OR, Feb 28-Mar 2, 2004 and at the Ist International qPCR symposium 3rd - 6th March, 2004 in Freising-Weihenstephan, Germany. Results are available below in several forms. All material is copyrighted and for scientific use only.

    8) NARG 2004 Taqman Primer/Probe Design Study

    The purpose of this study was to give investigators an opportunity to design an optimal set of primers/probe for a common gene and have them tested empirically for effectiveness. We were able to demonstrate some of the basic principles of Taqman Assay design. A table showing how the individual participants fared in their design efforts is posted below. Final analysis of results will be published in a peer reviewed journal. A copy of the poster presented at the ABRF 2004 annual meeting in Portland, OR, Feb 28-Mar 2, 2004 and at the Ist International qPCR symposium 3rd - 6th March, 2004 in Freising-Weihenstephan, Germany may be obtained by contacting sadams@trudeauinstitute.org.

    9) NARG 2003 Study Announcement

    Real-time PCR technology is of increasing importance in research. The commercial cost of dual-labeled probes for real-time PCR reactions is high because of traditional HPLC or gel purification steps. NARG believed that these probes may be used without purification, if carefully prepared, thereby reducing the cost and making the synthesis of real-time PCR probes feasible and practical for any DNA synthesis laboratory.

    NARG proposed to test whether all ABRF DNA synthesis labs are able to make quality dual-labeled probes suitable for real-time PCR reactions without requiring purification. It also wanted to determine the conditions under which highly purified probes may excel over unpurified probes.
