Abstract: The present disclosure provides isolated antibodies that specifically bind to human PD-L1, as well as antigen binding fragments of such antibodies, and kits comprising the anti-PD-L1 antibodies or binding fragments and a set of reagents for detecting a complex of the antibody, or antigen binding fragment thereof, bound to human PD-L1. The antibodies and antigen binding fragments of this disclosure are useful for immunohistochemical detection of human PD-L1 expression in tissue samples. Nucleic acid molecules encoding the antibodies and antigen binding fragments of this disclosure, as well as expression vectors and host cells for expression thereof, are also provided.

Abstract: The present disclosure describes gene signature biomarkers that are useful for identifying cancer patients who are most likely to benefit from treatment with a PD-1 antagonist. The disclosure also provides methods and kits for testing tumor samples for the biomarkers, as well as methods for treating subjects with a PD-1 antagonist based on the test results.

Abstract: The present disclosure describes an IHC assay for detecting and quantifying spatially proximal pairs of PD-1-expressing cells (PD-1+ cells) and PD-Ligand-expressing cells (PD-L+ cells) in tumor tissue, and the use of the assay to generate proximity biomarkers that are predictive of which cancer patients are most likely to benefit from treatment with a PD-1 antagonist. The disclosure also provides methods for testing tumor samples for the proximity biomarkers, as well as methods for treating subjects with a PD-1 antagonist based on the test results.

Abstract: Improved methods of measuring gene expression in intracellularly immunostained FACS-sorted cell populations are provided. Exemplary methods involve fixing cells with formalin and permeabilizing with mild detergent in the presence of ribonucleoside vanadyl complex prior to FACS sorting, followed by RNA extraction in the presence of de-crosslinking agents. The resulting RNA is suitable for gene expression analysis. The method allows for analysis of the gene expression pattern specifically associated with any sortable cell population or subpopulation.

Abstract: The present disclosure provides processes for describing and quantifying the expression of human programmed death ligand-1 (PD-L1) in tumor tissue sections as detected by immunohistochemical assay using an antibody that specifically binds to PD-L1. The results generated using these processes have a variety of experimental, diagnostic and prognostic applications.

Abstract: An offshore fixed platform support column assembly for deep water hydrocarbon development and production systems comprises an elongated cylindrical composite column which extends upward from a base assembly made up of a central cylindrical reinforced concrete caisson and one or more clusters of cylindrical reinforced concrete storage tanks to a point just below the sea surface. The column is made up of members having wound filament-resin composite cylindrical walls coupled end to end by coupling members which transmit tensile, bending and compressive loads between a platform structure supported at the upper end of the column assembly and the base assembly. The column members may include outer reinforced plastic shells forming buoyancy chambers which are filled with an expanded foam plastic buoyancy material.

Abstract: Tubular marine riser sections are formed by a wound or woven filament-resin matrix tubular body having a modulus of elasticity in tension of about 27,000,000 psi or greater utilizing carbon or boron for the filament material. The riser sections may be provided with end couplings secured to the tubular body for forming a riser system wherein the tensile strength or load bearing capacity of each section and its hydrostatic collapse resistance may be selectively determined by its position in the riser system. The riser sections may be provided with cylindrical collapse resisting ribs defining spaced buoyancy chambers filled with low density material contained by an outer shell formed of a glass or aramid fiber-resin matrix composite having a lower modulus of elasticity in tension than the primary load bearing tubular member. An inner abrasion and fluid impervious sleeve is disposed within the tubular body but is not bonded thereto.
