Sepharose? Protein A is a suspension of beads conjugated to a fusion protein containing binding domains from protein A from Staphylococcus aureaus. When evenly dispersed approximately 2.0 cc of suspension is equal to 1.0 cc of settled beads of Sepharose? 4 Fast Flow (highly cross linked, 4% agarose derivative). The bead size is approximately 45-165 μm when swollen. Approximately 6.0 mg of Protein A is bound per cc of drained beads. Each cc of drained beads will bind approximately 35 mg Human. The exclusion limit (Mr) of the beads is 3 x 10^7. The maximum linear flow rate is approximately 1300 cm/hr. This product shows long term stability within pH range of 3 to 9 and short term stability within pH range of 2 to 10.Synonyms: Sepharose Protein A
