Designed for greater sequencing depth and higher uniformity with low PCR duplicates, KAPA HyperExome Probes are Roche’s next generation of whole exome probe technology. 4. , 2012) were used to map the grain Dek gene in wheat rapidly. 45 to 91. Steps in the procedure and estimated times for each step, based on the processing of one solution phase capture, are shown in the boxes. All of the current hybridization-based mouse exome capture systems are designed based on the genome reference sequences of the C57BL/6 J strain. 3B). Exome Probesets (exomeProbesets) Track Description. RNA exome capture sequencing overcomes these challenges by combining RNA-Seq with exome enrichment. A single capture experiment was performed including mutants as well as. This method can expand the size of your target space.
