pCMV-SPORT6.1-OPA3 Plasmid

Chickemuel ligand-decorated gold nanoparticles for use in ex vivo modified dendritic cell-based DNA inoculation. Since mannose receptors (MRs) are expressed on the surfaces of dendritic cells (DCs), the most professional antigen-presenting cells in our body, DNA vaccine vectors containing covalently grafted mannosyl or shikimoyl ligands are used. increasingly on former DNA grafts. live-based transfection. To…

TMPRSS2 usage by SARS-CoV-2 Omicron impacts tropism and fusogenicity

Here we show that Omicron spike has higher affinity for ACE2 compared to Delta as well as a marked change of antigenicity conferring significant evasion of therapeutic monoclonal and vaccine-elicited  polyclonal neutralising antibodies after two doses. mRNA vaccination as a third vaccine dose rescues and broadens neutralization.Importantly, antiviral drugs remdesivir and molnupiravir retain efficacy against Omicron BA.1.…

genomic analyses of Polymyxin-resistant Enterobacteriaceae strains from China

Background: This has brought great challenges to the treatment of multidrug-resistant Escherichia coli and K. pneumoniae. Results: K. pneumoniae 16BU137 and E. coli 17MR471 were isolated from the bus and subway handrails in Guangzhou, China. K. pneumoniae 19PDR22 and KP20191015 were isolated from patients with urinary tract infection and severe pneumonia in Anhui, China. The mcr-1.1…

COVID-19 IgM/IgG Ab

Bottom Simple and rapid serological tests to characterize antibody responses are important in the current COVID-19 pandemic caused by SARS-CoV-2. Multiple immunoblot (IB) assays called COVID-19 IB assays were developed to detect IgG and IgM antibodies against SARS-CoV-2 virus proteins in COVID-19 patients. Methods The recombinant nucleocapsid protein and the S1, S2, and (RBD) receptor-binding…

DNA Ladder Step 100 Long 50Ug

Invitrogen 100 bp DNA Ladder is designed to approximately size and quantify double-stranded DNA in the range of 100 bp to 2000 bp. The 100 bp DNA ladder consists of 13 individual chromatographically purified DNA fragments and has reference bands at 2000, 1500 and 600 bp to facilitate orientation. The 100 bp DNA ladder is…

Detection Of Urinary Biopyrrin

Abstract Bottom Biopyrrins are end products of the oxidation reactions of bilirubin with reactive oxygen, and urine Bioperine (UBP) levels can increase under oxidative stress. The authors examined the reference UBP level for healthy adults and its physiological variation in 40 healthy volunteers recruited from students at our university (20 third and fourth-year students each)…

Autoimmune & Diagnostic ELISA (IVD)

About autoantibodies While self-tolerance mechanisms normally protect an individual from potentially self-reactive lymphocytes, there are flaws. They result in an inappropriate response of the immune system against the auto components called autoimmunity. Autoimmune diseases include more than 70 different disorders that affect approximately 5% of the population in Western countries. A large number of serum…

Post Vaccination Neutralizing Antibody Test

Bio-Plex Pro SARS-CoV-2 * Serology Assays provide COVID-19 researchers with sensitive and specific assays to monitor the immune response profile of antibodies against four viral antigens. There are three panels of isotype-specific 4 plexes that measure antibodies against the nucleocapsid, the receptor-binding domain, the receptor-binding domain, peak 1, and peak 2 of the SARS-CoV-2 viral…

covid 19 Diagnosis test series

covid 19 Diagnosis test series

CDC has developed two laboratory tests that identify SARS-CoV-2, the virus that causes COVID-19. The first test for COVID-19 diagnosis that CDC distributed, released in February 2020, is the CDC 2019-Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel, a test that accurately detects SARS-CoV-2 in respiratory specimens. CDC released a second assay in July 2020, the…

repid immunochromatographic xemat test penut

ABSTRACT A rapid (<7-min) immunochromatographic test for immunoglobulin M (IgM) and IgG antibodies to dengue viruses was evaluated by using hospital admission and discharge sera from 124 patients. The reference laboratory diagnosis was based on the results of virus isolation, hemagglutination-inhibition assay (HAI), and enzyme immunoassay (EIA). By the standard assays, patients experienced primary dengue…
