Phased 3-field HLA typing in a single assay using proven Scisco Genetics technology and the GeMS analysis software suite.
The human leukocyte antigens (HLA) are intimately involved in the innate and adaptive immune responses, communicating normal and abnormal cellular status to surveying immune cells. These highly polymorphic genes can greatly affect the outcome of hematopoietic cell and solid organ transplantation, in addition to their consequential roles in infectious disease, autoimmunity, and cancer.
Our NGS solution for HLA class I and II typing is carried out via multiplex PCR of HLA specific amplicons. Exon and flanking intron sequences from the HLA genes are amplified in 4 reactions, simultaneously tagged with index sequences (to distinguish samples), pooled, and sequenced. Data can be stored, analyzed on the cloud, and visualized on your desktop computer using our GeMS (Genetics Management System) analysis software.
Post-transplant analysis of the donor/recipient origin of white blood cells in peripheral blood and/or marrow.
A test for chimerism after allogeneic hematopoietic cell transplantation (HCT) is routinely performed as a prognostic measure of engraftment and related clinical outcomes. Chimerism tests employ methods commonly used in identity testing to distinguish and quantitate donor and recipient cells present in blood, bone marrow, and various tissues.
Our 4-reaction Chimerism assay employs simple to perform laboratory steps and takes advantage of Next Generation Sequencing (NGS) technology to advance testing into the next generation of sensitivity and accuracy. Our assay can be adjusted for capacity and sensitivity by varying the number of reactions used and samples analyzed. Turnaround times from DNA to data are comparable to other commonly used methodologies.
