Introduction to the NARG

The Nucleic Acids Research Group is focused on studying current topics related to any and all aspects of nucleic acids including protocols, sample preparation, and storage. Most recently the focus has been on evaluating the impact of problematic samples, either low quantity or degradation, on various labeling methods for NGS, qPCR and Microarrays. Membership is open to all interested ABRF members.

Current Year Study

1) NARG 2013-14 Research Study

ChIP-Seq from small amounts of DNA

The Nucleic Acids Research Group (NARG) study will characterize alternative library preparation chemistries that require significantly less DNA than the current standard, 10ng DNA. The aim is to evaluate how comparable the sequencing results are when a low input library preparation kit is employed as compared to the standard method. Illumina’s ChIP-Seq Sample Prep Kit will be used as the standard method. Drosophila melanogaster DNA ChIPed with an antibody against H3K4me3 will be prepared at one site and distributed to various laboratories for library preparation. Chemistries will be assessed at multiple laboratories and technical replicates carried out at each site.

Recent studies conducted by the Nucleic Acid Research Group (NARG) have focused on how fixation and degradation affects the detection of DNA methylation using several analysis methods. Mouse tissues were used to generate gDNA from matched source tissues that are both flash-frozen and formalin-fixed paraffin embedded. The resulting gDNA was assayed using conventional methylation detection methods including bisulfite sequencing, methylation sensitive PCR (MSP), methylation (in)sensitive restriction enzymes, methylation DNA immunoprecipitation (MeDIP) and methylated DNA binding protein analysis (MIRA).

7) 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.

8) 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.

9) 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.

10) 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.

    12) 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.
