SNPmikroarrayek

SNPmikroarrayek, or SNP microarrays, are a type of DNA microarray used for genotyping single nucleotide polymorphisms (SNPs). These arrays are designed with probes that bind specifically to different SNP alleles. By hybridizing labeled DNA from a sample to the microarray, researchers can determine which alleles are present at thousands or millions of SNP locations simultaneously. This high-throughput genotyping capability makes SNP microarrays a powerful tool in various fields.

In human genetics, SNP microarrays are widely used for genome-wide association studies (GWAS) to identify genetic variants associated with diseases and other traits. They are also employed in pharmacogenomics to predict an individual's response to certain medications. In agriculture, these arrays are used for marker-assisted selection and breeding programs, helping to identify desirable traits in crops and livestock. Forensic science utilizes SNP microarrays for individual identification and kinship analysis.

The technology relies on the principle of nucleic acid hybridization. DNA is extracted from a biological sample, labeled with fluorescent dyes, and then applied to the microarray. If a sample DNA sequence matches a probe on the array, it will bind (hybridize). The fluorescence intensity at each probe location is then measured, indicating the presence of a particular allele. Analyzing these fluorescence patterns allows for the determination of genotypes at numerous SNP loci across the genome. The development of SNP microarrays has significantly advanced our ability to study genetic variation on a large scale.
