Viral Vectors & Particles

Human Angiotensin converting enzyme 2 (ACE2), also known as ACEH, is an integral membrane protein found on the surface of cells in the lungs, arteries, heart, kidney, and intestines. ACE2 serves as the entry point into cells for some coronaviruses, including the two strains that caused outbreaks of Severe acute respiratory syndrome (SARS-CoV) and coronavirus disease 2019 (COVID-19) (SARS-CoV-2). <br />The ACE2 Lentivirus are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to be transduced into almost all types of mammalian cells, including primary and non-dividing cells. The particles contain an ACE2 gene (NM_021804.3) driven by an EF1a promoter.  

The bald lentiviral pseudovirion was produced without envelope glycoproteins such as VSV-G or SARS-CoV-2 spike. It contains the eGFP gene driven by a CMV promoter as the reporter. The bald lentiviral pseudovirion can serve as a negative control when studying virus entry initiated by specific interactions between virus particles and receptors.

The bald lentiviral pseudovirion was produced without envelope glycoproteins such as VSV-G or SARS-CoV-2 spike. It contains a firefly luciferase and eGFP cassette (Luc-P2A-eGFP) as the reporters, driven by a CMV promoter. The bald lentiviral pseudovirion can serve as a negative control when studying virus entry initiated by specific interactions between virus particles and receptors.

Topaz1, a yellow fluorescence protein (YFP), is one of the brightest and thermally stable green fluorescence proteins (GFP). The YFP (Topaz) Reporter Lentivirus contains replication-defective, VSV-G pseudotyped lentiviral particles that are ready to be transduced into almost all types of mammalian cells, including primary and non-dividing cells. The particles contain an EF1α promoter-driven YFP(Topaz) construct (a.a. sequence below), and confer both YFP (Topaz) expression and puromycin resistance to the target cells. YFP (Topaz) expression and transduction efficiency can easily be verified and optimized via fluorescence microscopy or flow cytometry. Topaz has an excitation wavelength of 514 nm, an emission wavelength of 527 nm, and extinction coefficient of 94,500M-1cm-1.  

Cell entry of SARS-CoV-2 depends on the binding of viral spike protein to cellular receptor ACE2. The SARS-CoV-2 Spike Lentivirus are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to be transduced into almost all types mammalian cells, including primary and non-dividing cells. The particles contain the full length SARS-CoV-2 spike gene (QHD43416.1) driven by an EF1a promoter.

Human transmembrane serine protease 2 (TMPRSS2) is an enzyme primarily expressed by endothelial cells across the respiratory and digestive tracts. It is involved in viral entry and spread of coronaviruses including SARS-CoV-2, the virus that causes COVID19. TMPRSS2 primes the spike protein by cleaving at the S1/S2 site, leading to the virus fusing to the respiratory epithelia on the cell surface through binding to ACE2. Blocking TMPRSS2 activity could potentially be an effective clinical therapy for COVID-19. <br />The TMPRSS2 Lentivirus are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to be transduced into almost all types of mammalian cells, including primary and non-dividing cells. The particles contain an TMPRSS2 gene (NM_005656.4) driven by an EF1a promoter.
