DADF-053
Product Name
Incomplete Freunds Adjuvant (IFA, Vaccine adjuvant)
Subclassification
Adjuvants for protein-based vaccines
Classification
Adjuvant
Storage
Shipped at room temperature and it should be stored at room temp. DO NOT FREEZE. Stable for 6 months.
Recommended Usage
Suggested Usage: Adsorption of most proteins can be achieved by mixing equal volume of the antigen (preferably in saline) with an equal volume of the adjuvant to form an emulsion. (Ovalbumin/IFA (1:1, v/v was tested). Protein left in the supernatant can be measured by protein assay or specific ELISA. Dosage: Mouse/Rat/G.Pig (50-200 ul gel; IM/SC)Rabbit (250 ul; SC/IM).
Description
Incomplete Freund's Adjuvant (IFA) consists of heat-killed Mycobacterium tuberculosis in a water-in-oil emulsion. Additionally, IFA has ligands for TLR2, TLR4, and TLR9. Injection of antigen in IFA induces a Th1-dominated response. Freund's incomplete adjuvant lacks the mycobacterium found in Complete Freund's Adjuvant so it minimizes the side-effects. For this reason, Incomplete Freund's Adjuvant is used for the boost injections IFA is being used as an adjuvant in 42 vaccines currently.
