Dynamic Binding Capacity DEAE

Macro-Prep^® DEAE Dynamic Binding Capacity

The effect of flow rate on the dynamic binding capacity of the Macro-Prep DEAE support. A sample containing 3 mg/ml BSA was separated on a 1 x 10 cm (3 ml) Macro-Prep DEAE column. Sample was loaded onto the column in 10 mM Tris-HCl, pH 7.6 (buffer A) and was eluted in 1 M NaCl in buffer A. Sample was applied until the eluting buffer had an A₂₈₀ value 50% of the incoming sample.

Flow Rate Properties

The effect of flow rate on separation and peak symmetry. A 5 ml sample containing 3.65 mg/ml each myoglobin, conalbumin, BSA, and soybean trypsin inhibitor was loaded onto a column containing 6.56 ml Macro-Prep DEAE support. The sample was loaded in 50 mM Tris-HCl, pH 7.6 (buffer A) and eluted in a gradient of 0–1 M NaCl in buffer A as follows: buffer A for 15 ml, 0–0.35 M NaCl in 85 ml, 0.35–0.65 M NaCl in 15 ml, 0.65–1 M NaCl in 15 ml.

Macro-Prep DEAE Support

Macro-Prep DEAE Support: Scaling up purification process

Scalability of separations on Macro-Prep DEAE support. Separation of a yeast enzyme concentrate (Sigma) under various conditions of scale. A, a 50 mg sample was separated on a 7.4 ml column (10 mm ID) using a flow rate of 78 cm/hr (1 ml/min) in an analytical flow cell; B, a 500 mg sample was separated on a 64 ml column (25 mm ID) using a flow rate of 78 cm/hr(6.4 ml/min) in an analytical flow cell; C, a 1 g sample was separated on a 64 ml column (25 mm ID) using a flow rate of 305 cm/hr (25 ml/min) in a preparative flow cell. For all separations, sample was loaded in 50 mM Tris-HCl, pH 8.3, washed with 1 column volume of the same buffer, and eluted in a linear gradient of 0–0.35 M NaCl in the same buffer for 22.5 column volumes.

DEAE Media Comparison

Comparing Purifications of Different of DEAE Supports

Sample separation with the Macro-Prep DEAE support and two other commercially available DEAE supports. A 100 µl sample containing 9 mg/ml each of myoglobin, conalbumin, ovalbumin, BSA, and soybean trypsin inhibitor was loaded onto a 0.5 cm ID column containing 2 ml of support. Sample was loaded onto the column in 50 mM Tris-HCl, pH 7.6 (buffer A) and was eluted with 1 M NaCl in buffer A. The flow rate was 153 cm/hr (0.5 ml/min). Scales offset for comparison.

Bio-Scale™ Mini Macro^®-Prep DEAE cartridges are 1 and 5 ml cartridges packed with Macro-Prep DEAE weak anion exchange support. This support was developed using a macroporous methacrylate polymer and meets the demands of analytical, semipreparative, and process-scale applications. This rigid, macroporous, hydrophilic 50 µm support provides exceptional capacity, resolution, and throughput in a chemically and mechanically stable form. Macro-Prep DEAE operates well at low and medium pressures and exhibits minimal volume changes in response to variations in pH or ionic strength. It can be sanitized with chaotropic agents and can be autoclaved. Macro-Prep DEAE provides consistent and reproducible results.

Advantages include:

High capacity for biomolecules
High resolution of complex biological mixtures
Rigid polymer matrix that allows high flow rates at moderate pressures
Hydrophilic matrix that reduces nonspecific binding
Macroporous beads that enhance access to ionic sites
High chemical, mechanical, and thermal stability

Bio-Scale Mini cartridges have a double-wall cartridge design* that provides extra durability and allows easy, reliable runs at pressures up to 45 psi with the aqueous buffers most commonly used for protein separation. Convenient, ready to use, and disposable, the cartridges have chemically compatible polypropylene parts. Bio-Scale Mini cartridges are designed for use with BioLogic systems, a peristaltic pump, or any chromatography system; simple luer fittings make connection to any system easy (see bulletin 5326).

Regulatory support files are available upon request. Bio-Rad Laboratories is an ISO 9001-registered corporation.
