Implementation of a high-resolution barcoding system In order to determine the clonal relationships of developing thymocytes, we used an endogenous barcoding system (Fig. 1a) that consists of three components19. (i) A construct for the ubiquitous expression of the Hprt gene-specific sgRNA (hU6:sgRNAHprt)19; (ii) A conditional Cas9 expression construct (Rosa26:LSL-Cas9-YFP) inserted into…

In vitro reconstitution of Escherichia coli CRISPR-Cas3 interference E. coli CRISPR-Cas3 is generally well-characterized type I CRISPR complexes in vitro and in vivo32,33,37,38. However, recombinant EcoCas3 protein is difficult to purify because of poor solubility and propensity to aggregate at 37 °C25,26,30,39. Co-expression of HtpG chaperon40 and/or low temperature growth at…

Abstract We previously reported highly specific genome editing in rice by CRISPR-Cas9 and Cas12a with single DNA double strand break (DSB) (Tang et al., 2018). Two concurrent DSBs by CRISPR-Cas9 could generate defined deletions (Zhou et al., 2014), inversions (Schmidt et al., 2020), and translocations (Beying et al., 2020). Off-target…

Introduction The clustered regularly interspaced short palindromic repeats (CRISPR)–CRISPR-associated (Cas) protein systems naturally exist in prokaryotes. They are RNA-mediated defense mechanisms to protect bacteria and archaea from invading nucleic acids (Barrangou et al., 2007). CRISPR–Cas systems are classified into two classes (1 and 2). Class 2 CRISPR–Cas require a single…

Clustered regularly interspaced short palindromic repeats (CRISPR/Cas9) have transformed genome engineering techniques. Numerous toolsets have been created to enable easy and efficient loss-of-function perturbations of functional genomic sites. Study: CRISPR/Cas9 deletions induce adverse on-target genomic effects leading to functional DNA in human cells. Image Credit: elenabsl/Shutterstock The CRISPR/Cas9 system’s elements…

Detecting NUMTS (nuclear mitochondrial sequences) in the whole genome sequenced data 0 Hi All, I want to detect NUMTS (nuclear mitochondrial sequences) that have migrated from the mitochondrial to the nuclear genome using the whole genome sequence data. What could be the best Bioinformatic approach ?? Their presence, extent and…
