产品说明

一般描述

Contains 85% Drakeol 5NF, 15% Arlacel A (mannide monooleate emulsifier). Heat sterilized. Contains zero colony forming units/ml.
The word "adjuvant" is derived from the Latin, adjuvare, meaning "to help." During immunization, an adjuvant is generally mixed with the antigen to enhance the rate and amount of antibody formed. The most popular complete adjuvant is that of Freund. It consists of killed and dried microbial cells suspended in an emulsifying oil. Adjuvant without the microbial cells is called "incomplete adjuvant." Complete adjuvant forms a stable water-in-oil emulsion with aqueous solution of antigen. When injected subcutaneously into animals, the emulsified antigen forms a depot from which antigen is delivered slowly and at sustained levels to the animal′s antibody-synthesizing system. The induced antibody response is usually high and sustained. In guinea pigs, an additional benefit from adjuvant is the delayed appearance of hypersensitivity.

包装

10 ml in Glass bottle

组分

10 ml of Freund′s Incomplete Adjuvant homogenized in the following amounts by weight:

85% Drakeol 5 NF (light mineral oil)

15% Arlacel A, mannide monooleate emulsifier

警告

Toxicity: Standard Handling (A)

制备说明

1. Take the vial of Friend′s Incomplete Adjuvant and fold the aluminum seal back to permit free access to the stopper. Be careful not to break the aluminum ring that holds the stopper in place.

2. Dissolve 50 mg of antigen in 5 ml sterile PBS, pH 7.0-7.3. Maintain or create sterility if at all feasible.

3. Draw the solution into a 10 ml syringe with a 1 inch 21 gauge needle.

4. Insert needle into adjuvant vial and forcibly drive solution into the vial. Withdraw about half the mixture into syringe and force it into the adjuvant vial again.

5. Repeat the mixing procedure in step 4 until a smooth, stable, milky, water-in-oil emulsion forms. Check if the emulsion is complete by expelling a drop from the syringe onto the water surface in a beaker. If the drop remains on the surface and does not disperse when the beaker is agitated slightly, the emulsion is adequate. A properly prepared emulsion is stable for days.
