Imject™ Freund's Incomplete Adjuvant (FIA)

Thermo Scientific Imject Freund's Incomplete Adjuvant is a popular nonspecific stimulator of the immune response for use in antibody production immunization protocols.

This product comes in 10 mL ampules that are convenient and ready-to-use. The water-and-oil emulsion greatly enhances immune responses to immunogens when mixed and injected with the prepared antigen, and is typically used for booster injections. The ampules comprise conveniently sized aliquots that provide long shelf life.

Highlights of Freund's Incomplete Adjuvant (FIA):
• Also called Incomplete Freund's Adjuvant (IFA)
• Water-in-oil emulsion without Mycobacterium
• Enhances immune response in booster injections
• Typically used for subsequent boosts after initial injection with FCA
• Disadvantage: difficult to mix with immunogen

Adjuvants are nonspecific stimulators of the immune response. When mixed with an antigen or immunogen, adjuvants help to deposit or sequester the injected material thereby helping to increase antibody response. Adjuvants enhance the immune response to compounds that are already immunogenic; they do not confer immunogenicity to non-immunogenic haptens. To make prospective antigens more immunogenic, it is necessary to conjugate them to a carrier protein or some other complex, immunogenic molecule.

For added safety when opening glass ampules, consider using our Ampule Breakers, which are disposable safety devices that protect the fingers when breaking open a glass ampule.
