GMSbiotech Inc, formerly operating as Genomics USA Inc, develops unique microarray technology for genetics and personalized medicine applications. The company's technology involves the Human Leukocyte Antigen (HLA), the genes which are responsible for detecting foreign substances and triggering the immune system. Such HLA screening includes the detection of drug molecules, bacteria and viruses as well as the process of self recognition. GMSbiotech has has also developed a means of avoiding the "DNA Purification Problem", the extensive sample preparation and sample QC required in applied genetics laboratories. GMSbiotech has also found a way to completely bypass DNA purification in its HLA-typing products: enabling routine HLA typing from a microliter (about 1/50th of a drop) of raw blood; or enabling HLA typing from about 1/10th of the dried blood in a single 2mm punch-out from a neonatal filter paper card; or enabling HLA typing from 1/50th of the rehydrated sample derived from an ordinary cheek swab.
