Fragment size distribution was similar when tagmenting with 30 ng/l Tn5R27S,E54K,L372P, while higher dilutions of the enzyme with constant input cDNA concentrations resulted in larger fragment sizes (Figure S2B in File S1). To date, we have successfully used the in-house-produced Tn5R27S,E54K,L372P transposase and our tagmentation-based library preparation protocol to investigate the differentiation of hematopoietic stem cells based on the transcriptomes of single cells isolated from bone marrow (Velten et al. Pre-packed cOmplete His-Tag Purification Columns are available in two sizes (1 ml and 5 ml) and are compatible with standard instruments for protein purification. (E) Pairwise correlation of read counts between three technical replicates (samples processed from the same cDNA on the same day) when using homemade Tn5R27S,E54K,L372P and the tagmentation protocol presented here. On the widespread and critical impact of systematic bias and batch effects in single-cell RNA-Seq data. PCR amplification was performed using the KAPA HiFi HotStart polymerase or KAPA HiFi HotStart ReadyMix (see Figure S6B in File S1).
