Microarrays
Sampled offers genotyping, transcriptome profiling, and methylation profiling arrays for in-depth exploration of genetic, transcriptomic, and methylation variations in samples, fostering discoveries in health and disease research.
What Are Sampled’s Microarray Services?
Sampled’s microarray services encompass genotyping arrays, transcriptome profiling arrays, and methylation profiling arrays to enable scientists to explore variation in the genomes, transcriptomes, and methylation status of their samples of interest, driving insights and discoveries across health and disease scenarios.
Genotyping Arrays
Sampled offers a cutting-edge genotyping array service for scientists investigating genetic variation. Leveraging Single Nucleotide Polymorphisms (SNPs), common nucleotide variants found throughout the genome, this service helps researchers explore genetic diversity, including complex diseases’ genetic markers. Sampled uses pre-designed or customized array plates from trusted platforms like Thermo Fisher or Illumina, integrated with validated genomic content from comprehensive databases. With complete reagent kits, innovative data analysis tools, and an automated workflow, Sampled provides a seamless, dependable, and cost-effective genotyping solution.
Transcriptome Profiling Arrays
Sampled’s transcriptome profiling array service is a comprehensive solution for scientists studying gene expression patterns in specific populations. It involves analyzing mRNA transcripts related to various research areas, including diseases, inheritance, and cell growth. The process entails reverse transcribing mRNA into cDNA, which is then analyzed within custom-designed array plates. This tailored approach allows for precise data collection, providing valuable insights into gene correlations and expression levels and facilitating meaningful scientific discoveries in your research.
Methylation Profiling Arrays
Sampled’s methylation profiling service is a powerful tool for scientists studying DNA methylation and its impact across various research areas. It provides insights into gene regulation and biomarker identification, with links to diseases like cancer, obesity, and neurodegeneration. Additionally, it can help scientists understand how environmental factors affect agrigenomics. Using Illumina microarrays, reagent kits, and automated instruments, this service allows high-throughput genome-wide methylation profiling, facilitating research on epigenetic variations and functional consequences. Sampled’s service is dedicated to supporting research efforts and driving discoveries in this field.

How Do Sampled’s Microarray Services Work?
Sample Preparation
Here at Sampled, we can process various samples for microarrays. For genotyping and methylation processing, we can process whole blood and saliva samples. For transcriptome profiling, we can process whole blood or cell line samples. Upon receiving samples, our in-house analytical sample processing team processes these, extracting high-quality DNA or RNA and performing quality control checks on the extracted samples. If we receive externally produced DNA/RNA samples, our team will perform the necessary quality control checks to ensure that only the highest quality nucleotides a microarray pipelines.
Microarrays
Once the high-quality DNA/RNA samples have been extracted and quality checked, our scientists perform microarray analysis using Thermo Fisher and Illumina platforms in combination with the GeneTitan, iScan, or GeneChip instruments and automated liquid handling systems. For all microarray workflows, the general steps to process the target DNA include amplification, fragmentation, hybridization, staining, and scanning.
Data Analysis
From the scanning of arrays, data files are generated for analysis. First, raw microarray data will be quality-controlled to ensure the workflow has successfully produced high-quality data. If no data analysis support is required, clients are provided the raw data for in-house analysis. Alternatively, our expert bioinformaticians can perform automated data analysis using custom analysis pipelines to help you get the most out of your data.
