What analytics services do we provide?
Sample Analysis & Discovery
At Sampled, we specialize in providing customized laboratory and scientific services for clients in the public and private research sectors. From traditional qPCR-based detection platforms to high-throughput microarrays, our automated processing systems allow for fast and accurate analysis of both human and animal samples. We also provide next-generation DNA gene sequencing services that can be optimized and scaled for virtually any organism or sample size.
Just some of our areas of expertise include (but not limited to):
- Informatics (Bioinformatics)
Genome analysis, whether it be in human, animal or a variety of organisms, whole genome, exome, or custom gene panel sequencing provides access to genomic information, discovery and translational (Clinical and Research) results to support a number of studies and products. These include, biomarker discovery, metagenomics applications, and within the healthcare setting, both hereditary and acquired disease/disorder discovery and treatment options.
Genotyping is the process of identifying and investigating genetic variants in an individual by sequencing their DNA and comparing it to that of another individual or a reference sequence. Minor genetic differences can have dramatic impacts on an individual’s phenotype, from basic physical attributes to pathological changes associated with disease.
To support genomic advances in the medical and general research fields, Sampled offers pre-validated and custom genomic sequencing services and custom genotyping panels capable of analyzing hundreds or thousands of samples for specific targets as well as whole-genome studies. We also offer low-, medium-, and high-throughput gene sequencing and gene expression profiling and gene copy number analysis.

Epigenetics is the study of heritable changes in gene function or phenotype that are not attributable to DNA sequence alterations. In the medical research field, epigenetic studies are important for understanding how environmental or behavioral factors influence an individual’s genetic susceptibility to disease.
Applications of epigenetic research include:
- Characterizing the mechanisms of complex diseases such as cancer, heart disease, and diabetes
- Identifying disease-relevant regulatory elements
- Evaluating the biological role of DNA methylation in diseases
At Sampled, our advanced microarray and NGS platforms allow for rapid identification of epigenetic events across entire genomes. Specific services we provide include:
- Bisulfite treatment (qPCR): Bisulfite DNA treatments convert cytosine residues to uracil while leaving 5-methylcytosine residues intact. The methylation status of the treated DNA segment can then be assessed using methylation-specific qPCR or direct sequencing.
- Methylation microarrays: Medium- and high-throughput Illumina Infinium methylation arrays allow methylation sites to be interrogated at the single-CpG-site level.
- Tiling arrays: Affymetrix GeneChip Tiling arrays enable the discovery of novel transcripts and provide site mapping of protein-DNA interactions across entire genomes.
- ChIP-seq: Chromatin immunoprecipitation sequencing (ChIP-seq) of chromatin immunoprecipitated DNA enables rapid identification of DNA binding sites for transcription factors and other DNA-binding proteins involved in gene expression mediation.
- Methyl-seq: Methylation sequencing (Methyl-seq) is a fast and economical method for detecting methylation patterns and revealing epigenetic modifications across whole genomes or within specific genomic regions.
- Long Read Seq: Metagenomics studies, full-length transcripts sequencing, and genome-wide DNA modification analysis can detect epigenetic modifications across a number of applications
Our epigenomic tools include:
- Affymetrix GeneChip® and GeneTitan® systems for high-throughput genotyping and gene expression analyses
- Illumina MiSeq, NextSeq500, and NovaSeq 6000 platforms, allowing for parallel sequencing of large sample sets
- PacBio SMRT instruments (PacBio Sequel) for several research purposes including whole-genome de novo genome assembly, full-length target sequencing, metagenomics studies, full-length transcripts sequencing, and genome-wide DNA modification analysis.

In recent years, researchers have identified several genes that influence an individual’s likelihood of developing early- or late-onset neurological disorders. These biomarker discoveries have led to many new disorder discoveries, but also interrogate will knowns disease such as Alzheimer’s disease. Using this data, Sampled designed and developed within its laboratory the first physician-use polygenic Alzheimer’s Risk test that detects both risk-associated and protective genes related to Alzheimer’s disease development. This information can subsequently be used by a physician to guide the patient’s lifestyle choices, allowing them to take proactive steps toward improving their health and potentially preventing or delaying symptoms. The physician and patient can also discuss potential drug therapy options aimed at minimizing cognitive and functional decline if symptoms become present.
Launched in the US in October 2021, our test includes the following features:
- Assessment of over 100,000 genetic variations associated with Alzheimer’s disease
- Easy-to-use testing procedure requiring a mouth swab or blood sample
- Unsupervised sample collection (e.g., home setting) available for elderly or vulnerable patients
Our Alzheimer’s Risk test can only be ordered by a physician, and patients are required to pay for the tests directly or through the physician. Once the test has been ordered, the testing process involves the following steps:
- Mouth swab or blood sample is collected
- Sample is returned to the processing laboratory
- Results are sent to the physician to discuss with the patient
We also offer a number of Poly Genic Risk Assessments for a number of conditions such as Cancer, Autoimmunity and Virology using various genotyping methods, array, qpcr and NGS
