Abstract: Provided are methods for the identification of mutant kinases that are resistant to inhibition by a kinase inhibitor. In some embodiments, the methods may be used to assess a test compound or kinase inhibitor for the risk of the development of resistance in vivo, e.g., during clinical administration to treat a disease such as a cancer.

Abstract: Provided are improved methods for identifying the substrate recognition specificity or activity of a protease, convertase (sortase), or kinase. In some embodiments, methods are provided for identifying the endogenous protease or convertase cleaving patterns (e.g., “cleaveOme”) inside the secretory pathway of a living cell. Select embodiments involve aspects of yeast endoplasmic reticulum sequestration screening and next generation sequencing. Methods of producing polypeptides in Kex2 knockout yeast are also provided.

Abstract: Embodiments concern compositions and methods involving recombinant antibodies to histone post-translational modifications. The invention provides compositions and methods for histone methyltransferase assays. In certain embodiments, the compositions and methods involve a recombinant antibody that binds histone H3 fragment harboring biomarkers such as H3K9me3 mark, H3K4me3 mark, H3K36me3 mark, H3K27me3, H3K9me3 and H3S10phos or a recombinant antibody that binds histone H4 fragment harboring H4K20me3 mark.

Abstract: Methods and apparatus provide vibration-free steered-beam antennas using a module to accommodate segregated de and rf signals. A phase-shifter element is disposed within an interior of the module. A radiating element is provided, and an rf interface is adapted to couple energy between the phase-shifter element and the radiating element. The rf interface is disposed entirely within the interior of the module and is adapted to provide an rf interface with the module substantially only through the radiating element. A dc interface is adapted to couple energy between the phase-shifter element and an electrical connection element disposed exterior to the module.
