The scientific community around the globe is on a mission to find therapeutic treatment for COVID-19 virus. From whatever angle you are going to tackle this challenge, we provide products to support your research in vaccine development, immunotherapy and drug discovery.

COVID-19 and Coronavirus Related Proteins

Coronavirus (COVID-19 S1) antigen (aa 1-674), (recombinant)

The spike protein (S) of SARS-CoV-2 is the most prominent structure on the outside of the viral particles and the most promising target for both vaccination studies and blocking of viral entry. The spike protein is responsible for binding of the ACE2 host receptor and viral entry. Spike protein-ACE2 interaction is thought to occur through key residues in the receptor binding domain (aa ~450-510).

Vaccine Development

Whether you are looking for antigen candidates in host immunity and vaccination efficacy studies, development of virus blocking peptides, study protein-protein interaction, or need positive controls, reliable and robust antigens are key to your research. Enzo offers a wide selection of coronavirus antigens.

Drug Discovery

Drug repurposing can be an important part of any drug discovery program and has led to several blockbuster drugs. High-content screens and high throughput biomarker monitoring have created new opportunities for pursuing new therapeutic applications.

SCREEN-WELL® FDA approved drug library V2

Accelerates drug optimization with a unique collection of compounds of known safety and bioavailability for diverse targets.

  • Contains more than 100 additional compounds compared to our previous FDA approved library versions
  • 100% known bioactivity and greatest degree of drug-likeness available
  • Recently approved FDA compounds are also included
  • We provide detailed information in our comprehensive documentation for each compound
Drug repositioning or repurposing can be an important part of any drug discovery program and has led to several blockbuster drugs (e.g. Viagra and Rogaine). High-content screens, new biomarkers and noninvasive imaging techniques have created new opportunities for pursuing novel indications for approved compounds. Being FDA approved and in use in the clinics, all of the compounds in SCREEN-WELL® FDA v. 2.0 Approved Drug Library have known and well-characterized bioactivity, safety and bioavailability - properties which could dramatically accelerate drug development and optimization. The library also avoids irrelevant compounds found in similar libraries, such as herbicides, insecticides, sunscreen agents, and cytotoxic agents. This set provides one of the richest sources of bioactives and offers the greatest degree of drug-likeness available. Hits from this set will provide a significant head start in any drug optimization program. Many of the compounds included can also be provided as standalone compounds for further testing.

Drug Discovery Assays

ADAM17 fluorometric drug discovery kit

Disintegrin and metalloproteinase domain-containing protein 17 (ADAM17), also known as TNF-alpha converting enzyme (TACE), plays an important role in shedding of the main SARS-CoV receptor, angiotensin-converting enzyme 2 (ACE2), and regulation of viral entry. Our ADAM17 fluorometric drug discovery kit is supremely suited to analyze pharmacological modulation of ADAM17 enzymatic activity.

Cytokine Storm Monitoring

Emerging data suggest that many patients infected with COVID-19 may die due to an excessive response of their immune system, characterized by the abnormal release of circulating cytokines, termed cytokine release syndrome (CRS). CRS plays a major role in the deterioration of COVID-19 patients from pneumonia through acute respiratory distress syndrome (ARDS) cumulating in systemic inflammation and ultimately multi-system organ failure.

This phenomenon of a plethora of cytokines wreaking havoc throughout the body is often vividly referred to as “cytokine storm”.

Many cytokines take part of the cytokine storm in COVID-19 patients including IL-6, IL-1, IL-2, IL-10, TNF-α and IFN-γ, however a crucial role seems to be played by IL-6, whose increased levels in the serum have been correlated with respiratory failure, ARDS, and adverse clinical outcomes.

Bradykinin Storm Monitoring

Bradykinin is a peptide that dilates blood vessels and makes them leaky. Recent studies have reported a significant increase in Bradykinin levels in SARS-CoV-2 infected people that has been referred to as a ‘Bradykinin Storm’. Increased bradykinin levels promotes the formation of a fluid in the lungs that prevents the transfer of oxygen to the blood and subsequently to all other tissues, a common abnormality in COVID-19. Although the ‘Bradykinin Storm’ seems to be responsible for the more severe symptoms of COVID-19, more research is still needed to have a clear understanding of how it functions.

We provide a Bradykinin ELISA kit for a sensitive and accurate monitoring of bradykinin levels in plasma, serum and urine samples. The kit is for research use only.

Bradykinin ELISA kit

  • Sensitive, reliably measure as little as 24.8 pg/ml of Bradykinin
  • Rapid results in just 3 hours from up to 41 samples in duplicate
  • Broad dynamic range to easily quantify high and low levels of Bradykinin
  • Easy-to-use liquid color-coded reagents reduce errors

Accelerated Protein Stability Assay

The PROTEOSTAT® Thermal Shift Stability Assay is a rapid, simple screening method based on a novel molecular rotor dye which detects protein aggregation. The assay does not require any prior knowledge of protein structure, sequence or ligand binding activity, and is performed on a thermally regulated fluorimeter or RT-PCR instrument.
  • Perform accelerated screening for protein stability as a function of pH, ionic strength, and concentration
  • Screen for ligand binding to proteins of unknown function
  • Screen protein variants to determine their relative stabilities or excipients to determine optimal protein storage conditions
  • Identify protein-protein interaction inhibitors
  • PROTEOSTAT dye is tolerant of detergents and hydrophobic compounds

Carbonic anhydrase I (1 μM) was incubated with 0 to 62.5 mM of TFMSA (trifluoromethane sulfonamide) in 25 mM MES, 50 mM NaCl, pH 6.1. The ProteoStat Thermal Shift Stability Assay demonstrates that ligand binding increases protein thermal stability by an amount proportional to the concentration of the ligand.
