I would like to read iteratively the same BAM file twice using htslib. My option is to use hts_open, sam_hdr_read, then sam_read1 as much as needed to read the file until EOF. Is there a possibility to “rewind”, and use sam_read1 again from the beginning of the file, without closing…

Primary cells PBMCs were either isolated from fresh buffy coats via density gradient centrifugation using Biocoll (Biochrom) or selected from a Leukapheresis material using in house T cell selection technology ATC.

Integrase-deficient lentivirus (IDLV) enables reverse transcription of an encoded payload from an RNA molecule into a DNA template, which creates a useful yet low-efficiency donor for HDR. We engineered the IDLV genome to include CRISPR ‘cut sites’ that match the intended genomic cut site (Fig. 1). Cas9 ribonucleoprotein electroporated into…

Modification of HDRTs with interstrand crosslinks increases HR during gene editing.
