  • Method for amplifying cDNA derived from trace amount of sample
    Patent number: 9708603
    Abstract: The problem to be solved by the present invention is to provide a method for preparing a sample for comprehensively and accurately analyzing gene expression in a single cell or a few cells, for example, by a large-scale DNA sequencer.
    Type: Grant
    Filed: November 21, 2012
    Date of Patent: July 18, 2017
    Assignee: HITACHI, LTD.
    Inventors: Hiroyuki Tsunoda, Huan Huang, Mari Ohta, Hideki Kambara
  • METHOD AND DEVICE FOR ANALYZING REACTION LIQUID AFTER NUCLEIC ACID AMPLIFICATION REACTION, AND DEVICE FOR PROCESSING REACTION LIQUID AFTER NUCLEIC ACID AMPLIFICATION REACTION
    Publication number: 20160333397
    Abstract: A reaction liquid after a nucleic acid amplification reaction is made suitable for various processes. A step of measuring the amount of a target product and the amount of a byproduct after performing a nucleic acid amplification reaction, and a step of determining that a process for removing the byproduct is needed when the abundance ratio of the target product to the byproduct is lower than a prescribed value, and determining the dilution ratio of a reaction liquid after the nucleic acid amplification reaction when the abundance ratio is higher than the prescribed value are included.
