Antiviral Drug Screening

To deal with emerging and re-emerging infectious diseases, new antiviral drugs will almost certainly be required in the long term. Antiviral screening methods are critical for developing broad-spectrum antiviral drugs and vaccines. Creative Biolabs, a world-leading provider of virology testing, provides a wide range of antiviral drug screening options, allowing you to combine and customize your program to meet your specific business needs.

Antivirals can work in a variety of ways, including:

  • Directly targeting viral proteins;
  • Targeting host cell factors that are required for virus replication;
  • Enhancing the immune system's response to the virus.

Our Capabilities

Antivirals work to keep viruses from infecting, replicating, and growing. Creative Biolabs offers antiviral drug screening services to assist our clients in identifying antiviral products in a wide range of cell-based and biochemical assays. Our services can be used to assess a wide range of antiviral drugs, including immune modulators, natural products, small molecules, biologics, and therapeutic antibodies. We can assist you in selecting the best assays for your specific drugs and mechanisms of action. The test drugs can be added at different stages of virus infection, including pre-infection, post-infection, and pre-incubation with the virus.

We employ traditional and common virology readouts such as high throughput quantification of cytopathic effect (CPE), TCID50, viral replication assay, hemagglutination inhibition assay, and high throughput immunofluorescence. Our high-content imaging collects high-content data, which is then used to identify and optimize new drug candidates. The immunofluorescence assay can visualize and quantify virus/viral vector infection and replication in living cells in real time.

Our well-trained team has extensive experience with all aspects of project development. We can create complex and tailored assays to meet specific antiviral drug screening requirements. In vitro antiviral assays include, but are not limited to:

Viral replication assay
Immunofluorescence assays with single or multiple rounds of infection
CPE assay
Endpoint dilution assays (TCID50)
EC50/CC50 assay
Cytotoxicity testing over the same range of concentrations
Hemagglutination inhibition assay (HAI)


We offer experience, technique, and expertise in antiviral activity evaluation. We guarantee:

  • Highly efficient antiviral drug screening
  • Tailored services and the best customer experience in the industry
  • High assay sensitivity and precision

Creative Biolabs offers antiviral screening services to help speed up antiviral development through early discovery. Most viruses can be tested using the antiviral assays we provided. Our scientific staff has the knowledge and experience to provide such assistance to academic and commercial entities. We recommend an appropriate screening protocol based on the indicators that customers need to detect, and then carry out the necessary screening tests and data collection for customer projects. From Monday to Sunday, our customer service representative is available 24 hours a day. Please contact us if you want to learn more about virology testing.
