This invention relates to reagents and methods for increasing specificity and efficiency of genome editing by CRISPR associated (Cas) protein systems, more particularly by Cas:guide RNA complexes, by blocking off-target nucleic acids from cleavage by Cas:guide RNA complexes.

Methods and compositions for blocking off-target nucleic acids from cleavage by CRISPR proteins

The present invention relates to guide RNAs comprising adaptor segments having one or more modifications, and their use in homologous recombination by CRISPR:Cas systems. The modified adaptor segments are resistant to degradation by RNaseH. The present invention also relates to a dual guide RNA strategy in which a first guide RNA directs a Cas enzyme to make a double-strand break at a first target sequence, and a second guide RNA comprises an adaptor segment attached to a donor polynucleotide, and binds a second target sequence that is offset from the first target sequence.

Compounds and methods for CRISPR/Cas-based genome editing by homologous recombination

A microfluidic device for separating target components from a source fluid includes one or more source channels connected to one or more collection channels by one or more transfer channels. The target components of the source fluid can be magnetic or bound to magnetic particles using a know binding agent. A source fluid containing magnetically bound target components can be pumped through the source channel of the microfluidic device. A magnetic field gradient can be applied to the source fluid in the source channel causing the magnetically bound target components to migrate through the transfer channel into the collection channel. The collection channel can include a collection fluid that is stagnant until a predefined volume of source fluid is processed or a predefined volume of target components accumulate in the collection channel, at which point collection fluid can be pumped into the collection channel to flush the target components out of the collection channel. The target components can be subsequently analyzed for detection and diagnosis.

Microfluidic device and uses thereof

A method and apparatus for continuously separating or concentrating particles that includes flowing two fluids in laminar flow through a magnetic field gradient which causes target particles to migrate to a waste fluid stream, and collecting each fluid stream after being flowed through the magnetic field gradient.
