The use of recombinant lentivirus pseudotyped with the coronavirus Spike protein of SARS-CoV-2 would circumvent the requirement of biosafety-level 3 (BSL-3) containment facilities for the handling of SARS-CoV-2 viruses. Herein, we describe a fast

Nitrate is one of the major inorganic nitrogen sources for microorganisms. Many bacterial and archaeal lineages can express cytoplasmic assimilatory nitrate reductase (NAS), which catalyzes the rate-limiting reduction of nitrate to nitrite in the

Non-receptor protein-tyrosine kinases regulate cellular responses to many external signals and are important drug discovery targets for cancer and infectious diseases. While many assays exist for the assessment of kinase activity in vitro, methods

Phlebotomine vectors, sand flies of the order Diptera, are known to transmit Leishmania parasites as well as RNA viruses (arboviruses) to humans. The arbovirus, Icoaraci Phlebovirus (BeAN 24262 - ICOV), used in this study was isolated from Nectomys

The diversity of lipid structures, properties, and combinations in biological tissues makes their extraction and analysis an experimental challenge. Accordingly, even for one of the simplest single-cellular fungi, the budding yeast (Saccharomyces

Nowadays, CRISPR (clustered regularly interspaced short palindromic repeats) and the CRISPR-associated protein (Cas9) system play a major role in genome editing. To target the desired sequence of the genome successfully, guide RNA (gRNA) is

Toxoplasma gondii is a highly prevalent protozoan pathogen throughout the world. As a eukaryotic intracellular pathogen, Toxoplasma ingests nutrients from host cells to support its intracellular growth. The parasites also encode full or partial

DNA transcription by RNA polymerases has always interested the scientific community as it is one of the most important processes involved in genome expression. This has led scientists to come up with different protocols allowing analysis of this

Plasmodium falciparum is a unicellular eukaryotic parasite that causes malaria in humans. The parasite is spread by Anopheles mosquitoes after ingestion of sexual stage parasites known as gametocytes. Malaria transmission depends on parasites

Surface proteins of Staphylococcus aureus and other Gram-positive bacteria play essential roles in bacterial colonization and host-microbe interactions. Surface protein precursors containing a YSIRK/GXXS signal peptide are translocated across the
