Swine IgG F(c) Fluorescein, Fluorescein Conjugated

This product was prepared from normal serum by delipidation, salt fractionation and ion change chromatography followed by papain digestion and extensive dialysis against the buffer stated above.   Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Fluorescein, anti-Swine IgG, anti-Swine IgG F(c) and anti-Swine Serum.  No reaction was observed against anti-Swine IgG F(ab')2 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. This product possesses the F(c) region, recognized by high-affinity Fc receptor proteins.
