Molecular Resource Core

The Rheumatic Disease Research Core Center, funded by the NIH through UTHSC, is available to provide molecular and technical support for UTHSC investigators that are conducting research in rheumatic diseases. The lab provides a variety of services including: extracting and measuring RNA and DNA, providing quantitative real time Polymerase Chain Reaction (PCR) assays and analyzing single nucleotide polymorphism (SNP). The center can provide researchers with detailed information on genes and their expression.


The RDRCC Molecular Resource Core Lab offers UTHSC researchers a wide range of genomic services starting from the extraction process, to developing primers and probes to analyzing polymerase chain reaction results. (Price List)

RNA Extraction

The Core Lab provides the client with a variety of RNA extraction and purification protocols which include: Qiagen, Gentra Systems, Promega, and Trizol.

After extraction, the samples are measured for quality and quantity. We currently use the Gene Quant Pro Classic Spectrophotometer by GE Healthcare.

DNA Extraction

We are currently using DNeasy by QiagenOpens External Link for DNA extraction and purification. This kit is designed for rapid isolation of total DNA from a variety of sample sources and is ideal for PCR.

Agilent 2100 Bioanalyzer

Lab on a Chip

For a graphic representation of the quality of samples the Agilent 2100 is used. This is typically needed when the samples are being processed for cDNA microarrays which requires high quality RNA.

Lab on a Chip

The 2100 bioanalyzer is a microfluidics based platform for measuring the quality of DNA, RNA, proteins and cells. It is the first commercial, analytical instrument based on lab-on-a-chip technology. One chip can run 12 samples. This provides an excellent alternative to messy, labor-intensive gels. The entire procedure takes two hours from start to finish. The data is presented in graph form.

The RDRCC Molecular Resource Core is equipped with the latest in PCR technology. We use the 7900HT Sequence Detection System developed by Applied Biosystems for detection and quantitation of PCR products.

Primers and probes can be designed, free of charge using Primer Express v2.0, for any gene whose nucleotide sequence is known . The RDRCC-MRC only charges for reagents, plates and the use of the 7900HT PCR instrument. See price list for more information.

We support Applied Biosystems Assays on Demand and Assays by DesignOpens External Link for gene expression and SNP detection.

TaqMan Low Density Array

Lab on a Chip

The RDRCC-MRC now has the ability to run 7900HT TaqMan Low Density Array. The mirco fluidic card delivers TaqMan performance in a low density array format. The TaqMan chemistry delivers the greatest sensitivity, with over 6-logs of dynamic range and the highest specificity in quantitative gene expression. The user can select from over 40,000 inventoried TaqMan gene Expression Assays: gene-specific primer and probe sets for quantitative gene expression of human, mouse or rat genes.

Micro fluidic technology enables small, 2ul volume, 384-well reactions without the need for robotic pipetting instruments. TaqMan Arrays are delivered with your primer and probe already lyophilized in the wells.

Two microliter reactions dramatically reduce enzyme consumption. Micro fluidic technology prevents evaporation and eliminates small-volume pipetting errors.
