Publication number: 20200224222Abstract: Many studies have shown that CRISPR-Cas nucleases can tolerate up to five mismatches and still cleave; it is hard to predict the effects of any given single or combination of mismatches on activity. Taken together, these nucleases can show significant off-target effects but it can be challenging to predict these sites.

Publication number: 20200224242Abstract: A rapid one-pass liquid filtration system efficiently concentrates biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream.

Publication number: 20200224267Abstract: A detection apparatus that includes (a) an array of responsive pads on a substrate surface; (b) an array of pixels, wherein each pixel in the array has a detection zone on the surface that includes a subset of at least two of the pads; and (c) an activation circuit to apply a force at a first and second pad in the subset, wherein the activation circuit is configured to apply a different force at the first pad compared to the second pad, and wherein the activation circuit has a switch to selectively alter the force at the first pad and the second pad.Type: ApplicationFiled: April 1, 2020Publication date: July 16, 2020Inventors: Robert C. Kain, Tarun Khurana, Kevin L. Gunderson, Yir-Shyuan Wu

Publication number: 20200224268Abstract: Embodiments disclosed herein provide methods for constructing a DNA profile comprising: providing a nucleic acid sample, amplifying the nucleic acid sample with a plurality of primers that specifically hybridize to at least one target sequence comprising a SNP and at least one target sequence comprising a tandem repeat, and determining the genotypes of the at least one SNP and at least one tandem repeat in the amplification products, thereby constructing the DNA profile of the nucleic acid sample. Embodiments disclosed herein further provide a plurality of primers that specifically hybridize to at least one short target sequence and at least one long target sequence in a nucleic acid sample, wherein amplifying the nucleic acid sample using the plurality of primers in a single reaction results in a short amplification product and a long amplification product, wherein each of the plurality of primers comprises one or more tag sequences.Type: ApplicationFiled: September 19, 2019Publication date: July 16, 2020Inventors: Kathryn M. Stephens, Cydne Holt, Carey Davis, Anne Jager, Paulina Walichiewicz, Yonmee Han, David Silva, Min-Jui Richard Shen, Sasan Amini, Frank J. Steemers

Publication number: 20200224269Abstract: The present invention is based on the use of the H3K9me2 methylation levels in plant genomes to predict transgene silencing, transgene stability, and/or transgene expression level. Provided are methods and/or systems for generating whole-genome H3K9me2 maps and its use with an assigned threshold value for predicting gene silencing. The methods and/or systems provided herein can be used in high-throughput setting for screening large number of transformed event in a relatively short period of time as compared to existing technologies.Type: ApplicationFiled: March 16, 2020Publication date: July 16, 2020Applicant: Dow AgroSciences LLCInventors: PoHao Wang, Shreedharan Sriram, Lakshmi Sastry-Dent

Publication number: 20200224271Abstract: In the field of transplant rejection, identified are SNPs wherein mismatches in variants present in a recipient and donor for such SNPs are predictive of transplant outcome, wherein the SNPs represent non-HLA loci newly implicated in rejection. By the invention, transplant outcomes such as elevated risk of antibody mediated rejection, elevated risk of T-cell mediated rejection, or low risk of rejection can be predicted by analyzing mismatches between donor and recipient for the enumerated SNPs. Certain SNPs enumerated are predictive of kidney transplant outcome. The compatibility of prospective donors can be assessed for a recipient, allowing for optimized donor-recipient pairing.Type: ApplicationFiled: July 16, 2018Publication date: July 16, 2020Applicant: The Regents of the University of CaliforniaInventors: Minnie Sarwal, Marina Sirota, Silvia San Juan Pineda
