Antiviral Peptides Screening Service

MtoZ Biolabs provides comprehensive Antiviral Peptides Screening Services integrating high-throughput screening technologies, molecular display systems, and LC-MS/MS analysis to identify peptides with strong antiviral potential. Our platform enables the rapid discovery of peptide candidates capable of inhibiting viral entry, replication, and transmission, supporting research and drug development across infectious diseases.

What Is Antiviral Peptide?

Antiviral peptides (AVPs) are short amino acid sequences that interfere with various stages of the viral life cycle. They can prevent viral attachment, block membrane fusion, inhibit replication, or suppress viral protein synthesis. Derived from natural sources or designed synthetically, AVPs offer broad-spectrum antiviral properties with low cytotoxicity.

Importance of Antiviral peptides:

• Provide promising alternatives to conventional antiviral drugs with fewer side effects.

• Act through diverse mechanisms, reducing the risk of viral resistance.

• Effective against multiple virus families, including influenza, HIV, hepatitis, and coronaviruses.

• Useful in both therapeutic development and preventive healthcare strategies.
