Ovine Interferon

Updated: 2026-09-11

Overview

Ovine Interferon is a type of interferon produced by sheep, primarily known for its role in antiviral defense and immune regulation. It belongs to the interferon-tau (IFN-τ) subclass, which is unique to ruminants. This protein is widely studied for its potential applications in veterinary medicine and immunology research. Unlike human interferons, ovine interferon exhibits species-specific activity, making it particularly valuable for studies on sheep and related species. Its ability to inhibit viral replication and modulate immune responses has led to its use in treating viral infections in livestock.

Physical and Chemical Properties

Ovine Interferon is typically available as a lyophilized powder, which can be reconstituted in aqueous solutions for experimental or therapeutic use. The protein has a molecular weight of approximately 20-25 kDa and is stable under recommended storage conditions. Its solubility in water or buffer solutions makes it convenient for laboratory and clinical applications. The protein’s activity is highly dependent on proper storage and handling, as improper conditions can lead to degradation and loss of efficacy.

Main Applications

In veterinary medicine, ovine interferon is used to treat viral infections in sheep, such as foot-and-mouth disease and bluetongue virus. Its immunomodulatory effects also make it a candidate for enhancing vaccine efficacy or managing autoimmune conditions in livestock. Researchers utilize ovine interferon to study immune responses in ruminants, providing insights into interspecies differences in interferon activity. Additionally, it serves as a model for developing novel antiviral therapies for both animals and humans.

Safety and Storage

Ovine Interferon should be handled with care to avoid contamination or degradation. Proper storage at -20°C in a dry, dark environment is essential to maintain its activity. Repeated freeze-thaw cycles should be avoided to prevent protein denaturation. While the protein is generally non-toxic, direct contact with skin or eyes should be avoided. Use protective equipment such as gloves and lab coats when handling. Allergic reactions, though rare, have been reported in sensitive individuals.

B2B Procurement Guide

When procuring ovine interferon, prioritize suppliers with proven track records in protein production. Key specifications to verify include purity (typically >95%), biological activity (measured in IU/mg), and endotoxin levels. Certificates of analysis (CoA) should accompany each batch. Bulk purchases may offer cost advantages, but ensure the supplier can meet scalability requirements without compromising quality. Consider logistical factors such as cold chain shipping to preserve the protein’s integrity during transit.
