CRISPR/Cas12a Powered DNA Framework-Supported Electrochemical Biosensing Platform for Ultrasensitive Nucleic Acid Analysis

Nucleic acid analysis using ultrasensitive and simple methods is critically important for the early-stage diagnosis and treatment of diseases. The CRISPR/Cas proteins, guided by a single-stranded RNA have shown incredible capability for sequence-specific targeting and detection. Herein, in order to improve and expand the application of CRISPR/Cas technology to the…

New Techniques and Complex Models

CRISPR systems that rely on inactivated Cas enzymes—that is, dead Cas (dCas) enzymes—never looked more alive. They harness the targeting power associated with CRISPR—but not the double-strand cuts. As such, they give researchers new ways to interrogate and manipulate gene function. Possibilities include CRISPR interference (CRISPRi) and CRISPR activation (CRISPRa)…

CRISPR Applications in Medicine Depend on Minimizing Off-Target Editing

By Rolf Turk, PhD Genome editing technologies, such as CRISPR, are being applied to better understand basic biological systems as well as to research new kinds of gene and cell therapies. The CRISPR-Cas9 system comprises a Cas9 endonuclease protein that forms a complex with a guide RNA (gRNA) molecule, which…

Controlling CRISPR | Optics & Photonics News

Light-based approaches for steering CRISPR–Cas9, the powerful Nobel Prize–winning genome-editing toolkit, promise to boost the technique’s precision and specificity—and might help bring it into clinical use. [Getty Images] In early 2011, two scientists walked the cobblestone streets of Old San Juan, the historic district of Puerto Rico’s capital. Recently introduced…

CRISPR: Guide to gRNA design

Introduction to CRISPR in SnapGene Genome editing technology has been evolving for many years. The Holy Grail of genome engineering has always been to introduce a specific genetic change that affects only the genomic target and leaves no undesired changes in the DNA. The discovery and application of the bacterial…
