Publication number: 20210254044Abstract: This invention relates to methods for capturing and encoding nucleic acid from a plurality of single cells. A plurality of solid supports is randomly placed into a plurality of compartments, such that the average number of solid supports per compartment, ?1, is less than 1, wherein each solid support carries (a) a unique identification sequence and (b) a capture moiety. A plurality of single cells is randomly placing into the plurality of compartments, such that the average number of cells per compartment, ?2, is less than 1. These random placement steps may be performed in any order. Nucleic acid is then released from each single cell and captured via the capture moiety, such that nucleic acid from each single cell is tagged with a unique identification sequence.Type: ApplicationFiled: October 8, 2020Publication date: August 19, 2021Applicant: Fluidigm CorporationInventors: Sten Linnarsson, Gioele Le Manno, Amit Zeisel

Patent number: 11078476Abstract: This invention provides a technology for isolating nucleic acids from wax-embedded samples that is superior to the current state of the art. Standard protocols with this objective typically comprise dissolving the wax-embedded sample in an organic solvent, extracting nucleic acids from the organic solvent into an aqueous buffer, and isolating the nucleic acids from the aqueous buffer. The technology described here includes using hexadecane as the solvent to dissolve the sample, precipitating and washing the extracted nucleic acids, and dissolving the nucleic acids in a lysis buffer that includes NP40 and SDS. By implementing the reagents and techniques described in this disclosure, the user can obtain a product that has better yield, less degradation, and contains more unique mRNA transcripts for subsequent sequencing and analysis.Type: GrantFiled: August 20, 2018Date of Patent: August 3, 2021Assignee: FLUIDIGM CORPORATIONInventors: Jian Qin, Peilin Chen, Ramesh Ramakrishnan
