Welcome
The JHU SNP Center is a high through-put genotyping facility featuring Illumina's BeadArrayTMtechnology, serving JHU and the scientific community at large.
The BeadArrayTMtechnology is a robust, flexible system which enables the analysis of a large number (1,000's) of genotypes using a relatively small quantity of DNA. The BeadLabTMcombines robotics, high-multiplex assays protocols, multi-array matrices, scanning instruments, LIMS, and automated allele-calling software to deliver high-confidence, highly accurate genotypes.
The technology takes advantage of the ability to bind 3-micron beads coated with hundreds of thousands of copies of a single-stranded nucleotide sequence onto acid-etched glass slides. It can assay as few as 48 SNPs using Illumina's proven Golden Gate chemistry and millions of SNPs with the Infinium chemistry slides. We provide all of Illumina's of the shelf products and can help you design your own experiment as well. See the various product links at the left for more details on your ever-changing options.
