Project description:The Illumina GoldenGate Genotyping Assay is a flexible, pre-optimized assay that uses a discriminatory DNA polymerase and ligase to interrogate 96 SNP loci simultaneously. This Assay utilizes the BeadArray Reader. Using this assay, we examined the distribution of the patients` genotypes to determine which genotype tends to have a better outcomes for cancer treatment.
Project description:Custom Affymetrix SNP used to assay 24 mothers for desired variants. Data processed using the Affymetrix SNP Genotyping Console (Version 4.2, Affymetrix Inc., Santa Clara, CA, USA).
Project description:Using Illumina® BovineHD Genotyping BeadChip assay, we applied single sperms genotyping from one single Holstein bull to preliminarily describe its recombination map. We received 56 single sperms with qualified genotype information and totally detected 1,526 autosomal crossovers.

Project description:Development of a genotyping-by-sequencing assay in American badger
Project description:We performed genotyping of Neuroblastoma Primary tumors using Illumina HumanHap 550 - v1,v3,v3duo and 610 Quad genotyping beadchips.
Project description:GeneSeek HD Bovine 77k Genotyping array is used to estimate population structure and ancestry of bovine and evaluate loci responsible for complex traits. Further, copy number variation of bovine can be estimated by GeneSeek HD Bovine 77k Genotyping array. Here, we estimate population structure and ancestry of Qinchuan cattle.
Project description:Natural mitochondrial DNA (mtDNA) sequence variation plays a fundamental role in human disease and enables the clonal tracing of native human cells. While various genotyping approaches revealed mutational heterogeneity in human tissues and single cells, current methodologies are limited by scale. Here, we introduce a high-throughput, droplet-based mitochondrial single-cell Assay for Transposase Accessible Chromatin with sequencing (mtscATAC-seq) protocol and computational framework that facilitate high-confidence mtDNA mutation calling in thousands of single cells. Further, the concomitant high-quality accessible chromatin readout enables the paired inference of individual cell mtDNA heteroplasmy, clonal lineage, cell state, and accessible chromatin regulatory features. Our multi-omic analyses reveals single-cell variation in heteroplasmy of a pathologic mtDNA variant (m.8344A>G), which we tie to intra-individual chromatin variability and clonal evolution. Further, using somatic mtDNA mutations, we clonally trace thousands of hematopoietic cells in vitro and in patients with chronic lymphocytic leukemia, linking epigenomic variability to subclonal evolution in vivo.
