ROTI®Garose-Protein G HPBeads, for biochemistry, 25 ml, plastic

For rapid and simple purification of antibodies with reasonable effort, affinity chromatography still is the first choice in most cases. ROTI®Garose-Protein A and G Beads offer the perfect solution for your specific application under medium pressure (MPLC, FPLC), if rapid flow rates are desired or if big samples volumes have to be purified.

• Rapid one-step purification of immunoglobulins from cell lysates and biological solutions
• High yield of very pure immunoglobulins
• Easy elution and regeneration
• Covalent binding of protein G in high ligand density

The matrix of ROTI®Garose-Protein A and G Beads consists of crosslinked and beaded 4 % agarose, coated and covalently coupled with protein A from Staphylococcus aureus and protein G from Streptococcus, respectively.

The recombinant protein A (recA) shares IgG binding properties with natural protein A of S. aureus Cowan strain I. It has high affinity for IgG from a variety of different mammalian species, also binding some populations of IgA and IgM.

Binding domains specific for albumin as well as cell walls and cell membranes have been removed in the recombinant protein G, in order to ensure the maximum specific IgG binding capacity. It has high affinity for IgG from a variety of different mammalian species, also binding IgG3 with high affinity.

Directions for use

Most immunoglobulins may be eluted in 100 mM glycin or citric acid buffer (pH 3.0). ROTI®Garose-Protein A and G Beads may be regenerated, making them very cost-effective.

May not be autoclaved.
