Composition and Methods of a Nuclease Chain Reaction for Nucleic Acid Detection

This invention leverages the nuclease activity of CRISPR proteins for the direct, sensitive detection of specific nucleic acid sequences. This all-in-one detection modality includes an internal Nuclease Chain Reaction (NCR), which possesses an amplifying, feed-forward loop to generate an exponential signal upon detection of a target nucleic acid.Cas13 or Cas12 enzymes can be programmed with a guide RNA that recognizes a desired target sequence, activating a non-specific RNase or DNase activity. This can be used to release a detectable label. On its own, this approach is inherently limited in sensitivity and current methods require an amplification of genetic material before CRISPR-base detection. 

Cellular Potassium Imaging Using A Ratiometric Fluorescent Sensor

The inventors developed a ratiometric fluorescent small molecule probe for potassium ion detection composed of a duo-fluorophore system (KR-1).

The probe was further applied to cellular potassium level detection using confocal microscope imaging technique. KR-1 enables simple determination of potassium levels in various cancer or non-cancer cell lines.

Sieve Container For Contactless Media Exchange For Cell Growth

Media that contains nutrients and growth factors is necessary to grow all types of cells, a process that is widely used in many fields of research. Such media should be routinely changed either to different media or a fresh batch of the same media. This change currently involves either using a pipette to transfer cells from their current dish of media to a new dish, or aspirating the media out of the dish and replacing it with new media. Both methods have inherent risks to stressing and damaging the cells. Researchers at UCI have developed a unique dish for growing cells that allows for safer aspiration of the old media, which reduces stress and damage to the cells.

Alignment-Free Rapid Sequence Census Quantification (Kallisto)

Sequence census experiments utilize next-generation sequence data to estimate the relative abundance of target sequences.  Since the samples are often short DNA fragments, they must first be assigned to the correct transcripts and genes that produced them, and this alignment or mapping step currently takes up the majority of computing power and time in most expression analyses. To avoid this costly process, UC Berkeley researchers have developed a software program (kallisto) for quantifying abundances of transcripts from RNA-Seq data, or more generally of target sequences using high-throughput sequencing reads based on pseudo-alignment for rapidly determining the compatibility of reads with targets, without the need for alignment. Pseudo-alignment of reads preserves the key information needed for quantification.

DNA Sequence Assembly Software (Design Evolver)

DNA sequence assembly software is used for designing the construction of longer DNA molecules from fragments of shorter DNA molecules. Current methods of sequence assembly are expensive, slow and prone to failure. Investigators at UC Berkeley have developed a sequence assembly tool, Design Evolver, which is cheaper, faster, easier to implement and less prone to failure than alternate tools. The software works in conjunction with the j5 DNA assembly tool developed and licensed by the Joint BioEnergy Institute (JBEI). Design Evolver’s algorithm can further optimize designs that have been processed by j5.

High-sensitivity Angular Interferometer

Researchers at the University of California, Berkeley have developed an invention that consists of an angular interferometer able to measure angle variations of a coherent, collimated light source with an accuracy below 30 nrad. The optical setup is compact and consists of a few simple optical components. The novelty of this innovation lies in the use of a simple, cost-effect technique to amplify the sensitivity of the instrument. The disclosed invention is in principle capable of being integrated into more compact, high-sensitivity commercial instruments for a fraction of the cost of current, state-of-the-art instruments (currently exceeding $30,000).   Commercial devices used to measure the angular deviation of a single beam include autocollimators and interferometers. The highest resolution offered by a commercial system is 25 nrad. The disclosed angular interferometer is able to measure relative angle variations (of a sample beam relative to a reference beam) below 30 nrad, though the resolution is known to currently be limited by the specific details of the current application and can therefore be further reduced with minor, inexpensive improvements.

A Method and Software Significantly Improving the Accuracy Of Genome Assemblies: SEQuel

Assemblies of next generation sequencing (NGS) data, while accurate, still contain a substantial number of errors that need to be corrected after the assembly process. Earlier assembly algorithms developed for Sanger sequencing follow an "overlap - layout - consensus" paradigm, where consensus refers to fixing errors in the contigs. Since this paradigm faces difficulties in short read assembly, most NGS assemblers employ a de Bruijn graph approach that effectively deals with large amounts of data. However, most NGS assemblers neglect the consensus step, i.e., there exists no postprocessing of the contigs in Velvet and many other popular assemblers. Relying on high and uniform coverage, NGS assembly algorithms push the burden of producing high quality assemblies onto the construction of the de Bruijn graph. Our work demonstrates that NGS assemblers can benefit from the use of a consensus step. There are currently no tools that aim to accomplish this same goal.

Gene Knockout And Replacement In Stem Cells

It is often advantageous to ascertain the biological purpose of a gene product by "knocking out" that gene and observing the phenotypic consequence(s). This is most often accomplished in whole animal experiments that are costly and take long periods of time related to the gestation period of the animal system. Here we divulge a system where this goal can be accomplished in a short period of time in laboratory cultured animal cells.
