Protein A   SEPHAROSE (商標名)

SepharoseTM Protein A is a suspension of beads conjugated to a fusion protein containing binding domains from protein A from Staphylococcus aureus.

Ideal for Western Blotting where photo sensitive Conjugated Antibodies such as IRDye Conjugated Antibodies and DyLight Conjugated Antibodies are used. Rockland Immunochemicals features both large and small boxes to fit varying size and volume requirements.

Antibody-binding protein specificity for Protein A, Protein G, and Protein A/G which demonstrate binding specificity to IgG immunoglobulin through an interaction in the Fc region of the heavy chain domain. Protein A and G each show some preferences to certain types of antibody subclasses, and proper reagent selection may be required, Protein A/G offers the widest range of antibody subclass binding. Another immunoglobulin binding protein is Protein L which binds to the kappa light chain of the F(ab’)2 region.
