Description: The Cereblon Binding Assay Kit (FP) is designed for testing and profiling of Cereblon (CRBN) inhibitors using Fluorescence Polarization. The assay is a competitive binding assay, based on the binding of fluorescently-labeled Thalidomide, a CRBN binder, to purified recombinant CRBN._x000D_ CRBN is the substrate recognition component of a DCX (DDB1-CUL4-X-box) E3 protein ligase complex that mediates the ubiquitination and subsequent proteasomal degradation of target proteins. CRBN is a direct protein target for the immunomodulatory and antiproliferative activities of thalidomide analogues such as lenalidomide and pomalidomide._x000D_ The Cereblon Binding Assay Kit (FP) comes in a convenient 96-well format, with enough purified CRBN, Cy5-labeled Thalidomide, and assay buffer for 100 enzyme reactions. In addition, the kit includes the CRBN inhibitor Pomalidomide for use as an inhibitor control._x000D_
The key to the CRBN Assay Kit is the fluorescently-labeled Thalidomide. Using this kit, only one simple step on a microtiter plate is required for CRBN reactions. The Cy5-labeled Thalidomide is incubated with a sample containing CRBN to produce a change in fluorescent polarization that can be measured using a fluorescence reader.

Description: This product includes 60 ul of 1000 x PSA dye for more than 200 assays with the assay volume of 0.3 ml using 96-well plates or cuvettes.

Description: Cell Biolabs? HIF-1 Alpha DNA Binding Activity Assay Kit is an immunoassay developed for rapid detection of activated HIF-1 in any protein sample. Active HIF-1 complex is captured on a double stranded oligonucleotide containing an HRE that is attached to the well. HIF-1 Alpha is then detected with an anti-HIF-1 Alpha antibody followed by an HRP conjugated secondary antibody. Each kit provides sufficient reagents to perform up to a total of 96 assays, and can detect HIF-1 Alpha from human, mouse, or rat. The HIF-1 DNA Binding Activity Assay takes only 4.5 hours to complete compared to a standard 3 day electromobility shift (EMSA) method.

Description: This product includes 150 µl of 10 x Buffer, 150 µl of 10 x ssDNA, 150 µl of 2 mg/ml E. coli single-strand DNA binding protein SSB and 100 µl of 4 x gel loading buffer.

Description: The PCSK9(D374T) [Biotinylated]-LDLR Binding Assay Kit is designed for screening and profiling purposes. The key to this kit is the high sensitivity of detection of biotin-labeled PCSK9(D374T) by streptavidin-HRP. Only a few steps on a microtiter plate are required for the assay. First, LDLR ectodomain is coated on a 96-well plate. Next, PCSK9(D374T) is incubated with LDLR on the plate.  Finally, the plate is treated with streptavidin-HRP followed by addition of an HRP substrate to produce chemiluminescence, which can then be measured using a chemiluminescence reader.
