Mutation detection using Surveyor™ nuclease

Mutation detection using Surveyor nuclease.

We have developed a simple and flexible mutation detection technology for the discovery and mapping of both known and unknown mutations. This technology is based on a new mismatch-specific DNA endonuclease from celery, Surveyor nuclease, which is a member of the CEL nuclease family of plant DNA endonucleases. Surveyor nuclease cleaves with high specificity at the 3' side of any mismatch site in...

In Vitro Nuclease Detection

Mutation detection using a novel plant endonuclease.

We have discovered a useful new reagent for mutation detection, a novel nuclease CEL I from celery. It is specific for DNA distortions and mismatches from pH 6 to 9. Incision is on the 3'-side of the mismatch site in one of the two DNA strands in a heteroduplex. CEL I-like nucleases are found in many plants. We report here that a simple method of enzyme mutation detection using CEL I can effici...

Mutation detection in Machado-Joseph disease using repeat expansion detection.

BACKGROUND Several neurological disorders have recently been explained through the discovery of expanded DNA repeat sequences. Among these is Machado-Joseph disease, one of the most common spinocerebellar ataxias (MJD/SCA3), caused by a CAG repeat expansion on chromosome 14. A useful way of detecting repeat sequence mutations is offered by the repeat expansion detection method (RED), in which a...

Accurate and sensitive mutation detection and quantitation using TaqMan Mutation Detection Assays for disease research

addressed the feasibility of obtaining sensitive, accurate, and reproducible mutation detection results in synthetic templates, cell lines, and FFPE tissue samples using TaqMan Mutation Detection Assays. Analytical performance assessed with synthetic templates and genomic DNA (gDNA) extracted from cell lines or model FFPE cell lines indicates that TaqMan Mutation Detection Assays have a minimum...
