Publication number: 20230314328Abstract: A branched flow imaging system capable of fluorescence microscopy is disclosed, the system including a light source configured to emit excitation light, a sample slide configured to hold a sample to be imaged, a medium providing a potential with a correlation length greater than the excitation light wavelength, and a sensor configured to capture fluorescence emission light emitted by the plurality of fluorophores of the sample. The medium may be positioned such that the excitation light branches into a plurality of light channels that are incident upon the sample slide so that each of the light channels randomly excites an individual fluorophore molecule of the sample. The degree of randomness of the distribution of the light channels on the sample may be determined by a difference between the correlation length of the potential and the wavelength of the excitation light.Type: ApplicationFiled: March 15, 2023Publication date: October 5, 2023Inventor: Justin COSTA

Publication number: 20230242974Abstract: The present disclosure in some aspects relates to methods and compositions for detecting and quantifying multiple analytes present in a biological sample by rolling circle amplification (RCA). In some aspects, the methods and compositions provided herein address issues associated with control of signal spot size and intensity for RCA products (RCPs) in a sample. In some aspects, provided herein are methods and compositions (e.g., probes and/or reaction mixtures) for slowing down RCA and/or decreasing the size of RCA products. In some embodiments, nucleotides or nucleotide analogs having a hydrophobic group (e.g., a hydrophobic modification on the base) are included in nucleotides for RCA and incorporated into the RCP product, leading to reduction of RCP size without the need of crosslinking an incorporated hydrophobic nucleotide or nucleotide analog to the RCP itself or another molecule.Type: ApplicationFiled: December 23, 2022Publication date: August 3, 2023Applicant: 10x Genomics, Inc.Inventors: Justin COSTA, Jorge Iván HERNÁNDEZ NEUTA

Patent number: 11709802Abstract: A cluster data replication system includes a plurality of network elements and controllers. The controllers form a cluster that is able to elect one of the controllers as a master controller with the others being follower controllers.

Publication number: 20210032776Abstract: The present disclosure relates to processes for inverting oligonucleotide probes in an in situ synthesized array. These processes can be used to reverse the orientation of probes with respect to the substrate from 3?-bound to a substrate to 5?-bound to another substrate. These processes can also be used to reduce or eliminate the presence of truncated probe sequences from an in situ synthesized array. These processes can preserve the original patterns of the synthesized oligonucleotide after the inversion. These process can be achieved via the formation of a hydrogel layer in-between a donor substrate and an acceptor substrate through a polymerization reaction forming the hydrogel layer.Type: ApplicationFiled: March 20, 2019Publication date: February 4, 2021Inventors: Paul DENTINGER, Justin COSTA, Glenn MCGALL, Filip CRNOGORAC, Wei ZHOU
