CD genomics can help you analyze genetic variation efficiently to meet diverse research needs. By utilizing Affymetrix and Illumina array platforms, we support high-throughput and multiplex processing to meet diverse research needs, delivering high-quality data at a low per-sample cost.

The Introduction to SNP Microarray

Powered by state-of-the-art variant detection and SNP genotyping technologies, CD genomics provides various genotyping services, delivering high-quality data at a low per-sample cost. Microarray is a valuable tool to enable researchers to explore genetic variants such as single nucleotide polymorphisms (SNPs) and large structural changes, from discovery applications to routine screening.

Affymetrix and Illumina genotyping microarrays both provide trusted performance with respect to precision medicine initiatives, clinical and translational research, pharmacology, consumer screening, and agricultural applications. Based on the species and the selection of SNPs, multiple genotyping strategies are available.

Advantages of SNP Microarray

  • Custom, flexible, and scalable;
  • High call rates (> 99%) and high accuracy;
  • Cost-effectiveness and high-throughput;
  • Identifies SNPs in a targeted or whole genome scale;
  • In addition to SNPs, other genetic differences, such as copy number variations, can be measured
  • Applied in biomarker discovery and validation, clinical testing, GWAS, pharmacogenomics, forensics, and breed discrimination.

SNP Microarray Workflow

The general workflow for SNP Microarray is outlined below. We have three well-recognized genotyping platforms (Table 1) for genome-wide or targeted identification of SNPs and copy number variations in a high-throughput and affordable manner. Our highly experienced expert team executes quality management, following every procedure to ensure confident and unbiased results.
