Sample Preparation and Isolation of RNA or DNA
Freshly Frozen and RNAlater®/RNARetain™-treated Tissues
Asuragen routinely isolates nucleic acid from a wide variety of sample types including plant tissue, human and other animal tissues, cell lines, blood, and bacteria. In addition, we have significant experience isolating nucleic acids from tissues that have undergone a variety of preservation processes including fresh, frozen, RNAlater-treated, OCT-embedded, and formalin fixed paraffin embedded (FFPE) . Learn more about how we qualify our methods and staff.
Not all tissues are equal. Consult with our experts to discuss your tissue types, tissue processing, and any downstream applications to obtain a better understanding of the amount of tissues required for your experimental design.

Description of Services
Features of these sample prep services:
- All RNA isolation methods optimized to recover miRNA
- Methods may utilize exogenous DNA or RNA spiked-in controls
- Asuragen-isolated RNA or DNA suitable for numerous downstream applications, including expression profiling and genotyping studies (click here for additional services)
- Basic histology services also available
Workflow for sample prep:
- Tissue disruption
- Organic extraction-based isolation and cleanup
- DNAse treatment (if applicable)
- QC by NanoDrop spectrophotometer and Agilent 2100 Bioanalyzer
- Re-purification and/or concentration if required
Deliverables
Regardless of downstream application, detailed QC reports including nucleic acid concentration, RNA integrity (RIN) and electropherograms (where applicable), and purity are provided on each sample. Purified nucleic acid samples are shipped back to you on dry ice. Asuragen ships samples Monday through Wednesday and will notify you upon shipment.
Isolation services are often utilized with Asuragen’s molecular profiling services. Surplus RNA or DNA will be discarded unless otherwise requested. Additional shipping charges may apply for the return of residual blocks, RNA, or DNA.
Quality Control
No matter how robust the downstream processes, good data is dependent on sample quality; consequently, accurate measurement of sample quality is essential before deciding if a sample merits further analysis. All samples prepared by Asuragen Services are routinely qualified by spectrophotometry with the NanoDrop spectrophotometer and the Agilent 2100 Bioanalyzer. If you have chosen to use Asuragen Services for additional services and a sample does not pass the recommended QC metrics for analysis, you will be contacted promptly to discuss possible solutions. These may include replacing the sample or re-isolating the RNA, excluding the sample from further analysis, or proceeding at-risk.
High Quality RNA
RNA was isolated from colon tumor tissue by Asuragen and run on the Agilent 2100 BioAnalyzer to show integrity (red line). The same RNA was incubated overnight at 37°C to show stability (blue line). This data shows that there was no change in RNA quality and integrity after extended incubation.
These rigorous procedures enable Asuragen to be the only service provider to offer a Data Quality Guarantee:
- If, for any reason, a qualified sample does not pass our process control specifications, we will re-run the sample at no additional charge.

Turn-around Time
Most projects are completed in two weeks or less. If you have a critical time requirement, we can often meet your need for no additional charge. Read more about our commitment to prompt turn-around times
