    摘要: Conformationally-constrained helicases having improved activity and strength are provided. Methods of making conformationally-constrained helicases having improved activity and strength are provided. Methods of using conformationally-constrained helicases having improved activity and strength are provided. The present invention is based on the discovery of novel modified helicases that show dramatically enhanced helicase activity and increased strength as compared to unmodified helicases. As described further herein, it has been surprisingly discovered that, by controlling the conformation of certain subdomains such that the helicase remains in a closed form (e.g., by covalently crosslinking the 2B domain to the 1A domain or the 1B domain in a Rep helicase), a highly active and strong form of the helicase is achieved

    摘要: A method of capturing a Circulating Tumor Cell (CTC) and Circulating Cancer Cells (CSC) from a sample includes introducing a sample into a flow based multichannel device having a cell capture surface and a flow modification surface under conditions that allow a CTC to bind to a cell rolling-inducing agent and a capturing agent disposed on the cell capture surface. The invention also provides for flow based multichannel devices to capture CTCs and CSCs from a sample.

    摘要: The invention provides polymers comprising Formula I: wherein monomer is a repeating unit comprising 2, 3, 4, 5, 6 or 7 carbon atoms and the monomers are linked together through amide or ester bonds; n is about 6 to about 1000; and Linker is an optionally substituted carbon chain that is optionally interrupted by moieties such as oxygen, nitrogen, sulfur, phosphorus, or silicon. Charge is a moiety having a positive or negative charge on a heteroatom, such as nitrogen, oxygen, phosphorus, or sulfur; where the Linker separates the monomer and the Charge by at least six linear atoms. The invention also provides methods of preparing the polymers and the copolymers and methods of using the polymers and copolymers, for example, as drug delivery systems, as membrane penetrating peptides, and as therapeutic agents.
