Application Note Rabbit IgG F(ab) Fragment can be utilized as a control or standard reagent in Western Blotting and ELISA experiments.
Purity Rabbit IgG F(ab) fragment was prepared from normal serum by a multi-step process which includes delipidation, salt fractionation, ion exchange chromatography and papain digestion followed by chromatographic separation and extensive dialysis against the buffer stated above.  Rabbit IgG F(ab) fragment was assayed by immunoelectrophoresis resulted in a single precipitin arc against anti-Rabbit Serum, anti-Rabbit IgG and anti-Rabbit IgG F(ab’)2.  No reaction was observed against anti-Rabbit IgG F(c) or anti-Papain.
Storage Condition Store vial at 4° C prior to restoration.  For extended storage aliquot contents and freeze at -20° C or below.  Avoid cycles of freezing and thawing.  Centrifuge product if not completely clear after standing at room temperature.  Rabbit IgG F(ab) fragment is stable for several weeks at 4° C as an undiluted liquid.  Dilute only prior to immediate use.

BACKGROUND

Secreted as part of the adaptive immune response by plasma B cells, immunoglobulin G constitutes 75% of serum immunoglobulins. Immunoglobulin G binds to viruses, bacteria, as well as fungi and facilitates their destruction or neutralization via agglutination (and thereby immobilizing them), activation of the compliment cascade, and opsinization for phagocytosis. The F(ab) fragment is the portion of the antibody that binds to the antigen target. The immunoglobulin F(ab) also possesses one constant and one variable region of both the heavy and light chain.
