Single Nucleotide Polymorphisms (SNPs) are single base changes in the genetic code, representing the most common type of genetic marker.
Xelect uses the Fluidigm EP1 microfluidic genotyping platform with a 96 SNP x 95 sample plate format giving a throughput of 576 samples/day.
For larger numbers of SNPs and/or haplotypes and up to 2,000 samples per run we use a genotyping-by-sequencing method with our Illumina Mi-Seq. We have a pipetting robot for DNA normalisation which also gives us the ability to handle multiple plate formats.
SNP genotyping for Genomic selection
From April 2018 Xelect will be offering the Illumina Infinium® Shrimp LD v1.0 BeadChip enabling genomic selection and family identification for Pacific white shrimp (Litopenaeus vannamei). The array contains in excess of 6400 SNPs distributed across the shrimp genome that have been shown to exhibit Mendelian inheritance across multiple breeding programs.
