Patents by Inventor Cynthia Chang

Cynthia Chang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11959078
    Abstract: Methods of preparing a next generation sequencing (NGS) library from a ribonucleic acid (RNA) sample are provided. Aspects of the methods include combining the RNA sample with a first strand cDNA primer and a template switch oligonucleotide under first strand cDNA synthesis conditions, where one of the first strand cDNA primer and the template switch oligonucleotide includes a first post-tagmentation amplification primer binding domain. The resultant product is subjected to amplification conditions sufficient to produce a double stranded cDNA, which is then tagmented with a transposome that includes a second post-tagmentation amplification primer binding domain. The tagmented sample is then subjected to amplification conditions using first and second post-tagmentation amplification primers that include sequencing platform adapter constructs to produce a NGS library. Aspects of the invention further include compositions produced by the methods and kits that find use in practicing the methods.

  • Patent number: 10870848
    Abstract: Methods of preparing a next generation sequencing (NGS) library from a ribonucleic acid (RNA) sample are provided. Aspects of the methods include combining the RNA sample with a first strand cDNA primer and a template switch oligo-nucleotide under first strand cDNA synthesis conditions, where one of the first strand cDNA primer and the template switch oligo-nucleotide includes a first post-tagmentation amplification primer binding domain. The resultant product is subjected to amplification conditions sufficient to produce a double stranded cDNA, which is then tagmented with a transposome that includes a second post-tagmentation amplification primer binding domain. The tagmented sample is then subjected to amplification conditions using first and second post-tagmentation amplification primers that include sequencing platform adapter constructs to produce a NGS library.

  • Publication number: 20070173837
    Abstract: A bone fixation and dynamization device comprising a first member having a first end and a second end; a second member having a first end and a second end, wherein the first end of the second member is coupled to the second end of the first member body, wherein the first member is linearly moveable relative to the second member; an actuator coupled to the first member; a feedback controller coupled to the actuator; an elongate rod having an actuator end coupled to the actuator and a fixed end fixed to the second member, wherein the actuator is operable to move the rod and the second member linearly relative to the first member responsive to the feedback controller; at least one bone engagement pin extending from the first member; and at least one bone engagement pin extending from the second member.
