Proseek single-plex protein assay kit system to detect sAxl and Gas6 in serological material of brain tumor patients
The receptor tyrosine kinase (RTK) Axl and its ligand Gas6 are critically involved in the pathogenesis of high-grade glioma (HGG). Both proteins were found to be overexpressed e.g. in tumor cells, mediating cell proliferation and migration as well as tumor angiogenesis and neuroinflammation. The extracellular domain of Axl (sAxl) and Gas6 were found in the…
Read MoreUtilization 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…
Read MoreEvaluation of the INDICAID COVID-19 Rapid Antigen Test in Symptomatic Populations and Asymptomatic Community Testing
As the COVID-19 pandemic progresses, there is an increasing need for rapid, accessible assays for SARS-CoV-2 detection. We present a clinical evaluation and real-world implementation of the INDICAID COVID-19 rapid antigen test (INDICAID rapid test). A multisite clinical evaluation of the INDICAID rapid test using prospectively collected nasal (bilateral anterior) swab samples from symptomatic subjects…
Read MoreIodixanol (Optiprep), an improved density gradient medium for the iso-osmotic isolation of rat liver peroxisomes
The suitability of Iodixanol {5,5′-[(2-hydroxy-1, 3-propanediyl)-bis(acetylamino)] bis-[N,N’-bis(2, 3-dihydroxypreopyl-2,4,6-triiodo-1,3-benzenecarboxamide)]}, a nonionic iodinated compound with a molecular weight of 1550, for the isolation of peroxisomes from rat liver was investigated. Centrifugation of light mitochondrial fractions in 20 to 40% (w/v) Iodixanol gradients, made iso-osmotic by the addition of sucrose, resulted in an excellent separation of peroxisomes from…
Read MoreEstablishment and characterization of a fucosylated α-fetoprotein-specific monoclonal antibody: a potential application for clinical research
The Lens culinaris agglutinin (LCA)-reactive fraction of α-fetoprotein (AFP-L3) is a well-known cancer biomarker for hepatocellular carcinoma (HCC) with very high specificity. Because LCA recognizes only bi-antennary N-glycans with a core fucose, some of fucosylated AFP in HCC patients may not be detected. Then glycan antibodies, which recognize both specific glycan and protein, are desired…
