A linear epitope coupled to DsRed provides an affinity ligand for the capture of monoclonal antibodies

Monoclonal antibodies (mAbs) dominate the market for biopharmaceutical proteins because they provide active and passive immunotherapies for many different diseases. However, for most mAbs, two expensive manufacturing platforms are required. These are mammalian cell cultures for upstream production and Protein A chromatography for product capture during downstream processing. Here we describe a novel affinity ligand…

Utilization of a direct sandwich ELISA kit for rapid diagnosis of adenovirus hemorrhagic cystitis in a patient with adult T-cell leukemia

We report on a case of adenovirus hemorrhagi cystitis that developed in a 49-year-old woman during intensive chemotherapy for adult T-cell leukemia. Although rapid etiologic diagnosis is essential for the effective management of viral hemorrhagic cystitis, the isolation of adenovirus from urine is often too time-cousuming. We detected the adenovirus antigen in the patient’s urine…

High-Throughput Screening of a Promoter Library Reveals New Persister Mechanisms in Escherichia Coli

Persister cells are a small subpopulation of phenotypic variants that survive excessive concentrations of bactericidal antibiotics. Their survival mechanisms will not be heritable and will be fashioned stochastically or triggered by environmental stresses equivalent to antibiotic therapy. On this examine, high-throughput screening of an Escherichia coli promoter library and subsequent validation experiments recognized a number…

IRE1α-driven inflammation promotes clearance of Citrobacter rodentium infection

Endoplasmic reticulum (ER) stress is intimately linked with irritation in response to pathogenic infections. ER stress happens when cells expertise a buildup of misfolded or unfolded protein throughout occasions of perturbation, comparable to infections, which facilitates the unfolded protein response (UPR). The UPR includes a number of host pathways in an try and re-establish homeostasis,…
