Protein A Sepharose® FF Resin designed for simple, one-step
and rapid antibody purification from serum, ascites and tissue culture
supernatant such as those derived from static cultures and bioreactors.
Recombinant
protein A has been coupled to Sepharose® to obtain a stable
matrix with a high binding capacity for immunoglobulins via the heavy chain of
the FC region (up to 30 mg/ml Human IgG). Antibody samples purified using this
affinity resin may be used in a wide range of laboratory procedures such as 1D
or 2D polyacrylamide gel electrophoresis, Western blotting, ELISA etc. Binding
affinity varies depending upon the source species and subclass.
