Rabbit IgG antibody (20 μl/ml) crosslinked to agarose beads was used to isolate RAT tagged proteins from whole cell extracts of 293T cells.Rabbit IgG crosslinked to agarose beads were used for purification of tagged protein from mammalian whole cell extracts at 0.5 to 1.0mg total protein to 10 μl of beads.

Rabbit IgG-Agarose has been used for immunoprecipitation and affinity purification assays.

General description

IgGs are glycoprotein antibodies that modulate several immune responses. IgG-Agarose is an immunoadsorbent that can be used to purify antibodies, remove species specific cross-reacting antibodies, or remove contaminating antibodies from an antiserum preparation. Characteristically, cross-reacting antibodies may be removed from an antiserum preparation using an equal resin volume of IgG-Agarose. However, the resin to antiserum ratio will vary with individual applications.
