|Description||HUMAN IgG F(ab) fragment|
|Host Isotype||IgG F(ab)|
|Buffer||0.01 M Sodium Phosphate, 0.15 M Sodium Chloride, pH 7.2|
|Species of Origin||Human|
|Reconstitution Volume||1.0 mL|
|Reconstitution Buffer||Restore with deionized water (or equivalent)|
|Preservative||0.01% (w/v) Sodium Azide|
|Purity||Human IgG F(ab) fragment was prepared from normal serum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by papain digestion and extensive dialysis against the buffer stated above. Human IgG F(ab) fragment assayed by immunoelectrophoresis resulted in a single precipitin arc against anti-Human Serum, anti- Human IgG and anti- Human IgG F(ab’)2. No reaction was observed against anti- Human IgG F(c) or anti-Papain.|

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.
