Biological Activity

Freund′s Adjuvants may be used to produce water-in-oil emulsions of immunogens. Antigens in water-in-oil emulsions stimulate high and long-lasting antibody responses which can be attributed to the slow release of antigen.

Freund′s adjuvant (incomplete) lacks the Mycobacteria found in Complete Freund′s Adjuvant so it minimizes the side-effects. It is used for boost injections. It was used to emulsify antigens that are injected into animals to produce monoclonal antibodies from the antiserum.

Each mL contains 0.85 mL paraffin oil and 0.15 mL mannide monooleate.

Chemical Information
Solubility (25°C) Antigens (preferably in saline) are typically mixed with an equal volume of the adjuvant to form an emulsion.
Storage 2-8°C, protect from light, sealed. Do not freeze!
Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Heparin sodium salt (MW 15kDa)

Heparin sodium salt (MW 15kDa) is a heparin polymer with a molecular weight of 15kDa.Heparin sodium salt is an anticoagulant that reversibly binds to antithrombin III (ATIII), thereby accelerating the rate of inactivation of Thrombin factor IIa and factor Xa by ATIII. Heparin sodium salt is used for blood collection and plasma preparation in experimental animals and for the construction of parenteral nutrition models in mice.
