Assays & Techniques

DNA and RNA Extraction

Accept many sample types including:

  • Saliva
  • Whole blood
  • Buffy coat
  • Serum
  • Buccal swabs
  • And more

Fully validated standard operating procedures (SOPs) are used with a number of automated and manual extraction approaches to obtain the highest quality and yield of DNA regardless of sample type.

Every DNA extraction is accompanied by a number of standard quality controls to ensure accuracy of sample assessment and ultimately better success on downstream applications. Quality control measures include:

  1. Quantitation – Fluorescent quantitation is commonly used to accurately determine the amount of double stranded DNA in a sample. We use a method involving the fluorescent dye PicoGreen to quantitate all samples that we extract.
  2. Purity assessment - An A260/A280 ratio is commonly used to assess the purity of a DNA sample following extraction. This can be accomplished by determining the ratio of spectrophotometric absorbance of the sample at 260 nm to that of 280 nm. We perform this assessment using a NanoDrop instrument.
  3. Integrity assessment - DNA integrity is critical for some downstream applications and to assess this agarose gel electrophoresis is performed to visualize the DNA before it can move on for further analysis. A single band with high molecular weight (>23kb) is an indicator of good sample integrity and a smear or otherwise lower molecular weight sample is an indicator of poor sample integrity.
Gel electrophoresis image demonstrating DNA samples with varying integrity. A single band showing molecular weight of 23kB or higher such as the first lane (1) show optimal integrity and suggest that the sample should be sufficient for most downstream applications. Smearing and decreasing overall molecular weight such as the samples in the remaining lanes (2-5) suggests lesser sample integrity. Samples with lesser sample integrity may not be sufficient for some downstream applications.

Other Services

  • Whole Genome Amplification (WGA) – Allows you to amplify the DNA in a precious sample so that it can be used for many assays in the future without the requirement of re-collection.
  • Aliquotting – Sample handling that allows you to have the sample distributed across multiple tubes and reduce or eliminate future freeze-thaw damage.
  • Storage – Sample storage can be arranged for months or years depending on requirements in a CLIA accredited, environment controlled facility.

SNP Genotyping

Single Tube SNP Genotyping

Best for projects with:

  • less than 1000 samples
  • fewer than 50 SNPs
  • Technology we use is TaqMan Single Tube assays. The TaqMan assay is an allele discrimination assay using PCR amplification and a pair of fluorescent dye detectors that target the SNP. One fluorescent dye is attached to the detector that is a perfect match to the first allele (e.g. an “A” nucleotide) and a different fluorescent dye is attached to the detector that is a perfect match to the second allele (e.g. a “C” nucleotide). During PCR, the polymerase will release the fluorescent probe into solution where it is detected using endpoint analysis in a real-time instrument.

Custom Arrays

Best for projects with:

  • more than 1000 samples
  • 50-500 SNPs
  • Technology we use is TaqMan OpenArray. This system involves the custom printing of the SNPs of interest onto an array and subsequent automated processing of those arrays.

Commercial Arrays

Best for projects with:

  • more than 100 samples (in some cases can be utilized with smaller sample numbers)
  • thousands to millions of SNPs

Platforms available:

  • Illumina
  • Affymetrix

Custom Content Available

Fragment Analysis (INDEL, VNTR or CNV)

A technology used to assess insertions or deletions in the gene sequence. We use an approach including polymerase chain reaction (PCR) to amplify the region of interest followed by capillary electrophoresis to determine the length of the fragments amplified.

Fragment analysis allows for the investigation of:

  • VNTRs – Variable number tandem repeats
  • CNVs – Copy number variants
  • INDELs – Insertions/deletions

Telomere Length Analysis (TLA)

This service is typically performed using a quantitative real-time PCR (qRT-PCR) method for absolute telomere length that can be found in O'Callaghan, N., V. Dhillon, P. Thomas, and M. Fenech. 2008 BioTechniques 44:807-809.

Other methods may be possible, please contact our Services Coordinator for more information.

Sequencing

We offer two types of sequencing technologies:

Next generation sequencing

  • Performed using the Ion Proton and Ion PGM platforms
  • Best used for targeted sequencing of large fragments of DNA (e.g. whole chromosome) and whole exome sequencing.

Sanger Sequencing

  • Best used for targeted sequencing of small to midsized DNA fragments (i.e. 100-1,000bp).

Frequently Asked Questions

What services does GenoFIND offer?

GenoFIND Services offers a wide variety of services including: nucleic acid extraction, genotyping, PCR- based assays, array-based assays and sequencing-based assays. In addition to extraction and downstream applications we also are able to offer a range of scientific consulting, bioinformatics and analysis services. We have access to a wide variety of platforms and qualified scientists with years of experience working with saliva samples so if you have any questions about a specific assay or analysis please contact your Sales Representative or the Services Coordinator for more information.

What should I do if I am not sure exactly what type of assay is the best choice for my project?

Contact your Sales Representative or the Services Coordinator for more information. Based on what you hope to accomplish we can usually recommend the most suitable technology for your project. If some background research is required a consulting scientist can review the literature from your field and make project recommendations.

I am not familiar with genomics. Can you help me to understand the data once my samples have been processed?

Our reports have been designed to be straightforward and easy to read. The Services Coordinator can also help you to understand the report and describe how to interpret it. If more in-depth analysis is required a consulting scientist can review your data and provide further interpretation.

How long will it take for my services to be performed?

The turnaround time for a project will vary dramatically depending on several factors including: number of samples, type of analysis and the queue at the lab. Typically most average sized projects can be completed within 3-4 weeks from the time that samples are received but if you require more rapid turnaround please let the Services Coordinator know. Remember the earlier you are in the queue the easier it will be to accommodate your timelines so always plan ahead.

What quality control measures come standard with your DNA extraction services?

We perform the following QC tests on all samples extracted:

  • Fluorescent quantification of dsDNA using PicoGreen
  • 260/280 Ratios by UV absorbance (to gauge purity)
  • Agarose gels (to gauge DNA integrity)

More information available here.

How do I ship my samples?

General Tips:

  • Make sure all caps are secure for transport.
  • Each sample must have a unique identifier written on the collection tube.
