SEPHAROSE PROTEIN A/G

Sepharose Protein A/G is a suspension of beads conjugated to a fusion protein containing binding domains from both protein A (from Staphylococcus aureaus) and protein G (from Streptococcus sp.). When evenly dispersed approximately 2.0 ml of suspension is equal to 0.5 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. Each cc of drained beads will bind approximately 20-30 mg Human IgG. The exclusion limit (Mr) of the beads is 3 x 10exp7. 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.
