Development of polyclonal chicken egg yolk immunoglobulin Y (IgY) antibodies targeting SARS-CoV-2 multi-epitope antigen.

Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is the primary cause of the Coronavirus disease 2019 (COVID-19) pandemic, which affects millions of people worldwide with high levels of infectivity and mortality. However, the antibodies developed for COVID-19 research and diagnostics are still limited. Therefore, in this study, we developed polyclonal immunoglobulin (IgY) antibodies from chicken egg yolk targeting multi-epitope antigen of SARS-CoV-2.

The SARS-CoV-2 M Dimer-Based Screening System: A Synthetic Biology Tool for Identifying Compounds with Dimerization Inhibitory Potential.

The COVID-19 endemic remains a global concern. The search for effective antiviral candidates is still needed to reduce disease risk. However, the availability of high biosafety level laboratory facilities for drug screening is limited in number.

Curcumin-derived carbon-dots as a potential COVID-19 antiviral drug.

Even entering the third year of the COVID-19 pandemic, only a small number of COVID-19 antiviral drugs are approved. Curcumin has previously shown antiviral activity against SARS-CoV-2 nucleocapsid, but its poor bioavailability limits its clinical uses. Utilizing nanotechnology structures, curcumin-derived carbon-dots (cur-CDs) were synthesized to increase low bioavailability of curcumin.

Porphyrin-derived carbon dots for an enhanced antiviral activity targeting the CTD of SARS-CoV-2 nucleocapsid.

Background: Since effective antiviral drugs for COVID-19 are still limited in number, the exploration of compounds that have antiviral activity against SARS-CoV-2 is in high demand. Porphyrin is potentially developed as a COVID-19 antiviral drug. However, its low solubility in water restricts its clinical application.

Development of Moloney Murine Leukemia Virus Reverse Transcriptase Fused with Archaeal DNA-binding Protein Sis7a.

Introduction: Moloney Murine Leukemia Virus Reverse Transcriptase (MMLV RT) is a common enzyme used to convert RNA sequences into cDNA. However, it still has its shortcomings, especially in terms of processivity and thermostability. According to a previous patent, the fusion of polymerase enzyme to an archaeal DNA-binding protein has been proven to enhance its performance.

Analysis of SARS-CoV-2 Genomes from West Java, Indonesia.

West Java Health Laboratory (WJHL) is one of the many institutions in Indonesia that have sequenced SARS-CoV-2 genome. Although having submitted a large number of sequences since September 2020, however, these submitted data lack advanced analyses. Therefore, in this study, we analyze the variant distribution, hotspot mutation, and its impact on protein structure and function of SARS-CoV-2 from the collected samples from WJHL.
