Background COVID-19 pandemic has spread worldwide since December 2019. Serological tests for SARS-CoV-2 antibody testing are needed for detection of current or past infections. A wide range of commercial tests is available. However, most of them need to be validated. Study design The aim was to compare a commercial IgG and IgA ELISA (Euroimmun) with three lateral flow immunoassays (LFI): Hangzhou Alltest Biotech, Wuhan UNscience Biotechnology...
Towards middle-up evaluation of polyclonal antibodies: subclass-specific N-glycosylation profiling of murine immunoglobulin G (IgG) by the use of HPLC-MS In latest years, superior HPLC-MS methods based mostly on intact protein ("top-down") or protein subunit ("middle-up/middle-down") evaluation have been carried out for the characterization of therapeutic monoclonal antibodies. Here, we assess feasibility of middle-up/middle-down evaluation...
The prokaryotic expression, polyclonal antibody preparation, and subcellular localization of the transmembrane protein NS2A of the duck Tembusu virus Duck Tembusu virus (DTMUV) is a single-stranded, positive-sense RNA arbovirus, belonging to the genus Flavivirus, household Flaviviridae. As a transmembrane protein, non-structural protein 2A (NS2A) performs an essential position in virion meeting, replication complicated and antagonizing...
Preparation and Characterization of Two Immunogens and Production of Polyclonal Antibody with High Affinity and Specificity for Darunavir Darunavir (DRV) is a potent antiviral drug used for therapy of infections with human immunodeficiency virus (HIV). Effective and secure therapy with DRV requires its therapeutic drug monitoring (TDM) in affected person's plasma throughout remedy. To assist TDM of DRV, a selected antibody with excessive...
Development of a Highly Sensitive Enzyme-Linked Immunosorbent Assay for Mouse Soluble Epoxide Hydrolase Detection by Combining a Polyclonal Capture Antibody with a Nanobody Tracer Enzyme-linked immunosorbent assays (ELISA) for the detection of soluble epoxide hydrolase (sEH), a key enzyme within the metabolism of fatty acids and a biomarker, could more and more characterize an essential diagnostic device. However, there's a lack of ELISAs...
Generation of High Affinity Anti-Peptide Polyclonal Antibodies Recognizing Goat α s1-Casein The chemical, technological and allergy properties of goat's milk are considerably affected by the extent of αs1-casein. Detection and quantification of αs1-casein requires high-specificity strategies to beat high-sequence similarity between this protein and others within the casein household. Unavailability of antibodies with excessive affinity...
Evaluation of Laboratory Application of Camelid Sera Containing Heavy-Chain Polyclonal Antibody Against Recombinant CTLA-4 Protein. Cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) is a critical negative immunomodulatory receptor that is normally expressed in activated T cells and noticeably, in many cancerous cells. Indeed, molecular detection of CTLA-4 protein is crucial in basic research. In this work, the extracellular domain...
Prokaryotic expression of mouse Stra8 and preparation and identification of rabbit anti-mouse Stra8 polyclonal antibody Objective To prokaryotically express mouse stimulated by retinoic acid gene 8 (Stra8) and prepare rabbit anti-mouse Stra8 polyclonal antibody. Methods The recombinant plasmid pET28a-Stra8 was constructed by cloning technology and identified by double enzyme digestion and sequencing, and then transformed into E. coli...
Efficient detection of eukaryotic calcium-sensing receptor (CaSR) by polyclonal antibody against prokaryotic expressed truncated CaSR Calcium-sensing receptor (CaSR), which is better known for its action as regulating calcium homeostasis, can bind various ligands. To facilitate research on CaSR and understand the receptor's function further, an in silico designed truncated protein was developed. The resulting protein folding indicated that...
Although bats are more and more changing into the main focus of scientific research on account of their distinctive properties, these distinctive animals are nonetheless among the many least studied mammals. Assembly high quality and completeness of bat genomes differ loads and particularly non-coding RNA (ncRNA) annotations are incomplete or just lacking. Accordingly, customary bioinformatics pipelines for gene expression analysis...
