Description

This product was prepared from normal serum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by pepsin digestion and extensive dialysis against the buffer stated above. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Sheep IgG, anti-Sheep IgG F(ab')2 and anti-Sheep Serum

Background: IgG F(ab)2

Sheep IgG F(ab')2 Fragment is a proteolytic fragment of immunoglobulin G (IgG) obtained by limited digestion with the enzyme pepsin under controlled conditions of temperature, time and pH. Sheep IgG F(ab')2 molecules lack the Fc portion of Sheep IgG and therefore receptors that bind Sheep IgG Fc will not bind Sheep IgG F(ab')2 molecules. This product possesses the F(ab')2 fragment, recognized by the two F(ab) fragments yielded from the digestion of the antibody below the disulfide bond hinge region.
