GC Genome/Celemics: SARS-CoV-2 BTSeq Sequencing Service

Korean firms GC Genome and Celemics have launched a SARS-CoV-2 sequencing service. As part of the service, GC Genome will use Celemics' Barcode-Tagged Sequencing (BTSeq) technology, which can analyze sequence sizes of less than 1 kb to a maximum of 30 kb with an error rate of less than .001 percent per base pair, the companies said. This enables analysis of both PCR products and full SARS-CoV-2 genomes. Turnaround time is usually less than 10 days but can be minimized to one day, the companies said. The partners said that the service can reveal information on the epidemiology and pathogenesis of the virus and enable mutant surveillance.

The Scan

Missed Early Cases

A retrospective analysis of blood samples suggests early SARS-CoV-2 infections may have been missed in the US, the New York Times reports.

Limited Journal Editor Diversity

A survey finds low diversity among scientific and medical journal editors, according to The Scientist.

How Much of a Threat?

Science writes that need for a provision aimed at shoring up genomic data security within a new US bill is being questioned.
