ChromSpeed™ S101 & S103

ChromSpeed™ S103 & S101 is a member of the ChromSpeed™ family of ion exchange media, especially designed for large molecules including monoclonal antibodies (MAbs) at process scale. ChromSpeed™ is composed of a rigid, high-flow methacrylate matrix with excellent ion exchange capacity. Particles sizes of 30 μm and 60 μm are available for such process scale providing high selectivities.

Hydraulic data

The rigid matrix of ChromSpeed™ S101 and S103 enables higher flow rate operation than conventional resins. There is a linear relationship between the flow velocity and the pressure drop of the packed bed even at higher flow rate, and there is no change in resin volume or resin shape.

Figure 1. Pressure drop data. Data were taken with a condition of a column 20 mm ID x 200 mm with water at a room temperature.

Separation of standard proteins

As representative purification performance, Figure 2 depicts separation of standard proteins. The uniform media of ChromSpeed™ on the last two in the figure shows in better efficiency comparing not only competing polymer media but also other media including cellulose and agarose media.

Figure 2. Standard proteins of cytochrome c and lysozyme separation. Data were taken with a column: 5mm ID x 100 mm, eluent A: 20mM sodium phosphate (pH6.5), eluent B: A + 1.0M NaCl, flow rate: 1.0 mL/min (r.t. 2 min), gradient: 0-100% B over 60 min of samples: (a) cytochrome c (pl 9.3) + (b) lysozyme (pl 11.0) = 125 / 125ug / 50uL.

Alkali tolerance of ChromSpeed™

Alkali tolerance of ChromSpeed™ is shown to be strong with 0.5M NaOH washing cycles as shown in Figure 3.

Figure 3. Alkali tolerance measured with 0.5M NaOH, 15min/cycle and DBC: IgG at 10 % breakthrough. Recovery was measured to be >99% with 1.0 g/L, 20mM Sodium acetate (pH 5.5).
