A Transgenic Heavy Chain IgG Mouse Platform as a Source of High Affinity Fully Human Single-Domain Antibodies for Therapeutic Applications

The antibody repertoires of transgenic mice expressing human heavy chain only antibodies (HCAbs) can be retrieved from immune cells after antigen challenge. Compared with genetically modified rodents expressing conventional human antibodies (tetramers consisting of two heavy chains paired with two light chains), there is no chain pairing problem, since each antibody consists of a heavy…

The Discovery and Function of Filaggrin

Keratohyalin granules were discovered in the mid-19th century in cells that terminally differentiate to form the outer, cornified layer of the epidermis. The first indications of the composition of these structures emerged in the 1960s from a histochemical stain for histidine, followed by radioautographic evidence of a high incidence of histidine incorporation into newly synthesized…

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…

Crystal structure and energetic features of the cocrystal of carbamazepine with 3,5-dinitrobenzoic acid.

The synthesis and detailed description of the crystal structure and energetic features of the 1:1 cocrystal of carbamazepine (5H-dibenzo[b,f]azepine-5-carboxamide, CBZ) with 3,5-dinitrobenzoic acid (35DNBA), i.e. C15H12N2O·C7H4N2O6, are reported. The CBZ and 35DNBA molecules are packed in alternately arranged layers. Two characteristic R22(8) and R22(16) hydrogen-bond ring motifs have been found. The supramolecular architecture, besides the…

Anti-Fel d1 immunoglobulin Y antibody-containing egg ingredient lowers allergen levels in cat saliva

Fel d1 is the major cat allergen, causing IgE reactions in up to 90% of cat-allergic adults. Fel d1 secreted in saliva is spread to the haircoat during grooming. Current management includes attempts to reduce or eliminate exposure to Fel d1. A novel approach to reducing immunologically active Fel d1 (aFel d1) exposure, which involves…

Direct RT-qPCR assay for SARS-CoV-2 variants of concern (Alpha, B.1.1.7 and Beta, B.1.351) detection and quantification in wastewater

Lower than a 12 months following the Extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, variants of concern have emerged within the type of variant Alpha (B.1.1.7, the British variant) and Beta (B.1.351, the South Africa variant). Resulting from their excessive infectivity and morbidity, it has grow to be clear that it’s essential to rapidly…

Author Correction: A simple and robust real-time qPCR method for the detection of PIK3CA mutations

Background: Extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has precipitated a pandemic of pneumonia spreading all over the world, resulting in critical threats to public well being and attracting monumental consideration. There’s an pressing want for delicate diagnostic testing implementation to regulate and handle SARS-CoV-2 in public well being laboratories. The quantitative reverse transcription PCR (RT-qPCR) assay is…

maxRatio improves the detection of samples with abnormal amplification profiles on QIAgen’s artus HIV-1 qPCR assay

Background: Correct viral load (VL) willpower is paramount to find out the efficacy of anti-HIV-1 remedy. The standard methodology used, fit-point (FP), assumes an equal effectivity within the polymerase chain response (PCR) amongst samples which may not maintain for low-input templates. Another strategy, maxRatio, was launched to compensate for inhibition in PCR. Strategies: Herein, we assessed whether or…

Roadblock-qPCR: A simple and inexpensive strategy for targeted measurements of mRNA stability

Roadblock-qPCR: A simple and inexpensive strategy for targeted measurements of mRNA stability

The steadiness of mRNAs is key to figuring out expression degree and dynamics. Nonetheless, present approaches for measuring transcript half-lives (e.g. transcription shutoff) are usually poisonous or technically advanced. Right here we describe an alternate technique for focused measurements of endogenous mRNA stability that’s easy, cheap, and non-toxic. Cells are first metabolically labelled with the…
