scTHS-seq combinatorial indexing R5, human H1 P39 endoderm day 4 cells (differentiated)/mouse heart nuclei (scT7_r0XX_i5) and Tn5059

  • Performing THS-seq on H1 P39 endoderm day 4 differentiated cells and mouse heart nuclei. will use 1000-2000 cells per reaction, and less are viable. Mouse forebrain tissues from bings lab were grinded up, heart nuclei are not so maybe it will give better results.
