We have recently isolated a cDNA encoding a novel human receptor-type tyrosine phosphatase, termed PTP-RO (for a protein tyrosine phosphatase receptor omicron), from 5-fluorouracil-treated murine bone marrow cells. PTP-RO is a human homologue of murine PTPlambda and is related to the homotypically adhering kappa and mu receptor-type tyrosine phosphatases. PTP-RO is expressed in human megakaryoc...

Idiotypes and antiidiotypes are thought to be important immune regulators and have provided clues for the origin and pathogenicity of autoantibodies. Many lupus and Sjögren's syndrome patients, as well as most neonatal lupus infants with congenital heart block or dermatitis, have antibodies to the ribonucleoprotein Ro/SSA, which is one of a group of RNA-protein autoantigens commonly found in hu...

As reverse osmosis (RO) desalination capacity increases worldwide, the need to reduce its specific energy consumption becomes more urgent. In addition to the incremental changes attainable with improved components such as membranes and pumps, more significant reduction of energy consumption can be achieved through time-varying RO processes including semi-batch processes such as closed-circuit r...

The design of reverse osmosis (RO) networks is investigated here using a mixed-integer non-linear programming (MINLP) approach based on a superstructure. A flexible superstructure that contains all possible alternatives of a potential RO network was developed and was used in the synthesis of RO networks. The networks were designed by using DuPont’s B10 Hollow Fiber module. For fixed freshwater ...

The Ro 60 kDa autoantigen is a major target of the immune response in patients with systemic lupus erythematosus. In vertebrate cells, Ro binds misfolded small RNAs and likely functions in RNA quality control. In eukaryotes and bacteria, Ro also associates with small RNAs called Y RNAs. We present structures of unliganded Ro and Ro complexed with two RNAs at 1.95 and 2.2 A resolution, respectiv...

BACKGROUND Receptor occupancy (RO) assays measure drug target engagement, and are used as pharmacodynamic (PD) biomarkers. RO assays are commonly performed by flow cytometry and often require multiplexing for assessment of multiple PD biomarkers when specimen volumes are limited. We present multiplexed RO assays for an IGF1R-EGFR bispecific antibody (Bs-Ab) and a CTLA4-Ig recombinant fusion pro...
