10x Genomics linked-read technology comes in two versions; the older GemCode (v1) and more recent Chromium Genome (v2). Long DNA fragments are combined in droplets with barcode-containing gel-beads to create GEMs ((Gel Bead-In EMulsions). The fragments are amplified and barcoded using a combination of free random hexamers and barcode-linked random hexamers from the gel beads. Following this barcoded fragments are recovered and fragments before ligation of 3' sequencing adaptor. Libraries are sequenced using Illumina Sequencing. The commercial version of the technology is currently discontinued.

TELL-seq is based on the technology from Chen et al. 2020 and is commercially available from the company Universal Sequencing. The method uses clonaly barcode beads with attacted tagmentases to cut and barcode individual long DNA fragments in solution. A second tagmentation is also preformed in solution to introduce a second adaptor. The library is sequenced using Illumina sequencing with special setup to sequence the barcode as index 1.

stLFR (single-tube long fragment read) is based on the technology described in Wang et al. 2019 and is commercially available from MGI. The technology uses tagmentation to individually cut-and-hold long DNA fragments in solution. The tagmentase-DNA complex is then hybridized and individual wrapped around barcoded beads through the adaptor introduced by the tagmentation. The barcode is then ligated to each subfragment before recovery and final library prepration. Sequencing is preformed on the DNBSEQ platfroms.

Droplet Barcode Sequencing (DBS) is based on the technology described in Redin el al. 2019. Long DNA fragments are subjected to tagmentation using Tn5-covered beads to cut, tag and wrap the fragment around the beads. The DNA-wrapped beads are then used in emmulsion PCR along with barcoded oligo. Within each emmulsion droplet the barcode and tagged fragments are amplified independently and then linked using overlap-extension. Barcode-linked fragments are recovered and indexed for Illumina sequencing.

Technologies based Amini et al. 2014 and the follow-up CPTv2-seq from Zhang et al. 2017. These technologies were developed by Illumina but are not commercially available.

Haplotagging is based on the technology presented in Meier et al. 2021. The technology uses barcoded beads covered with Tn5 tagmentase to cut and barcode individual long DNA fragments in solution. The beads are coated in a combination of two barcodes AB and CB that become inserted at the 5' and 3' of each cut fragment. Barcodes are combinatorialy generated with about 85 million possible combinations in total.
