Summary of "A Competitive Pull-down Assay Using G-quadruplex DNA Linked Magnetic Nanoparticles to Determine Specificity of G-quadruplex Ligands."

Herein we develop a new competitive screening method in which G-quadruplex DNA linked magnetic nanoparticles pull down selective ligands for a particular quadruplex topology from a series of small molecules. The screening strategy is first optimized with known G-quadruplex ligands and then used with a series of newly synthesized G-quadruplex interactive bis-triazolyl ligands by Cu(I) catalyzed azide-alkyne cycloaddition. The assay enables the identification of c-MYC and BCL2 G-quadruplex selective bis-triazole ligands that specifically target promoter G-quadruplexes in cancer cells.

Medical and Biotech [MESH] Definitions

The assay of INTERFERON-GAMMA released from lymphocytes after their exposure to a specific test antigen, to check for IMMUNOLOGIC MEMORY resulting from a previous exposure to the antigen. The amount of interferon-gamma released is usually assayed by an ENZYME-LINKED IMMUNOSORBENT ASSAY.

The pull on a limb or a part thereof. Skin traction (indirect traction) is applied by using a bandage to pull on the skin and fascia where light traction is required. Skeletal traction (direct traction), however, uses pins or wires inserted through bone and is attached to weights, pulleys, and ropes. (From Blauvelt & Nelson, A Manual of Orthopaedic Terminology, 5th ed)

A screening assay for circulating COMPLEMENT PROTEINS. Diluted SERUM samples are added to antibody-coated ERYTHROCYTES and the percentage of cell lysis is measured. The values are expressed by the so called CH50, in HEMOLYTIC COMPLEMENT units per milliliter, which is the dilution of serum required to lyse 50 percent of the erythrocytes in the assay.

Sensitive assay using radiolabeled ANTIGENS to detect specific ANTIBODIES in SERUM. The antigens are allowed to react with the serum and then precipitated using a special reagent such as PROTEIN A sepharose beads. The bound radiolabeled immunoprecipitate is then commonly analyzed by gel electrophoresis. Radioimmunoprecipitation assay (RIPA) is often used as a confirmatory test for diagnosing the presence of HIV ANTIBODIES.

A method of detection of the number of cells in a sample secreting a specific molecule. Wtih this method a population of cells are plated over top of the immunosorbent substrate that captures the secreted molecules.
