Equilibration 1. After column packing, wash with 1.5 CV of a buffer of the same composition as that chosen for equilibration, i.e., PBS. 2. Continue to equilibrate the column until the ionic strength and pH of the buffer at both the outlet and the inlet of the column are identical. 8. Ordering Information Blue Trisacryl M Sorbent 4.2. Sample Application 1. Ensure the absence of bubbles in the sample. Pack Size Part Number 2. Inject the sample into the column through a pump and then connect the pump to a buffer reservoir or to a gradient system. 5 mL 25896-051 25 mL 25896-045 3.

Working Flow Rate Dynamic binding capacity may slightly vary as a function of residence time. For a 10 cm bed height column, use a flow rate of 100 to 150 cm/hr, 6 to 4 minutes residence time. Working flow rate should not be above packing flow rate 4.4. Choice of Elution Gradient and its Slope Blue Trisacryl M AcroSep Column Description Part Number Blue Trisacryl M, 1 mL, Dark Blue 5/pkg 25896-C001 For preliminary studies, make an ionic strength linear gradient using sodium chloride up to 3 M in phosphate buffer. After running, optimize the elution conditions, particularly the final NaCl concentration. The elution can also be performed more specifically by cofactor gradients (NAD, NADP) or with more eluents such as ethylene glycol, urea, potassium isothiocyanate. 5. Regeneration and Cleaning Regenerate the column with 2 to 4 CV of 3 M NaCl, followed by a cleaning-in-place (CIP) with 5 CV of 0.1 M HCl or 10 mM NaOH at room temperature. In some cases, 6 M urea or 50% ethylene glycol can also be used. After regeneration treatment, re-equilibrate Blue Trisacryl M sorbent in the starting buffer. 6. Autoclaving Equilibrate Blue Trisacryl M sorbent in a neutral buffer without any phosphate and any other products unstable at high temperature. Autoclave the sorbent at 121 °C for 20 minutes. After sanitization, the column must be re-equilibrated in the normal sterile pyrogen-free buffer.

Product Description Blue Trisacryl M sorbent is a dye-affinity chromatographic sorbent used for the purification of a wide variety of enzymes and proteins such as kinases, albumin, interferons, and some coagulation factors. The basic matrix is the macroporous non-ionic Trisacryl GF2000 support on which Cibacron blue 3GA has been covalently immobilized. Blue Trisacryl M sorbent is available in a variety of package sizes, and also in 1 mL AcroSep™ column for fast screening laboratory applications. 2. Properties Particle size Cibacron blue 3GA 107 Da Exclusion limit Capacity for human albumin 1 ≥10 mg/mL Thermal stability 2 to 121 °C Working pH 4 to 10 Cleaning pH 1 to 12 (short term) Working pressure at 100 cm/hr Up to 3 bar (45 psi) 5. When the top of the bed stabilizes, stop the pump and unscrew the O-ring seal. Position the adjustable piston at the top of the packed sorbent by turning the screw-lock mechanism, leaving no visible space between the frit and packed sorbent at any point around the circumference. Re-tighten the O-ring seal. 6. Operate the pump again and repeat the adjustment of the piston until no visible space appears under flow between the frit and the top bed. 3.2.4. Evaluating Column Performance Column performance is evaluated by determining column efficiency, expressed as either plates/meter (N/m), or HETP (Height Equivalent to one Theoretical Plate). Additionally, the asymmetry factor (AF) is calculated. Required formulas are shown below. Measurements are made as follows: 1. Equilibrate a column of 15 mm I.D. x 20 cm length such as Pall LRC column 15/80-200, with packing buffer (PBS). 2. Inject 1% column volume (CV) of 5% acetone solution. Apply a flow rate of 100 cm/hr. Record UV absorbance at 280 nm. To determine the packing performance, use the following formulas: 3.2.2. Preparing Column and System for Packing 40 – 80 μm Ligand 5. Gently agitate the slurry and let the sorbent settle. Remove the supernatant and add 3 to 5 volumes of fresh packing buffer. 6. Repeat step 4 a total of 3 times minimum. 7. Gently agitate the slurry, pour it into a measured cylinder and allow the sorbent to settle. 8. Remove the supernatant and add a volume of packing buffer equal to one-half the volume of settled sorbent. A slurry of 50 % (v/v) – the concentration recommended for packing – is obtained. 1 Determined in 25 mM phosphate sodium, 150 mM NaCl, pH 7.4 using 5 mg/mL protein, column dimensions: 16 mm I.D. x 6 cm bed height, flow rate 25 cm/hr 3. Column Packing 3.1. General Considerations Blue Trisacryl M sorbent is supplied as a slurry/suspension in 1 M NaCl with 20% (v/v) ethanol as bacteriostatic. 1. Prime the solvent delivery system, lines and valves to ensure that all air is displaced. Ensure that top and bottom frits or nets are fully wetted and free of air. Fill the column with packing buffer and operate the system over a range of flow rate representative of values that will be used during packing and anticipated chromatographic procedures. Record pressure associated with the empty column and system (including detectors, etc.). 2. Determine pressure/flow characteristics for the empty system, taking into account recommendations concerning flow rate during packing and chromatographic operation. 3. Stop the pump, close the column outlet, and remove the upper flow-adaptor or piston. 4. Open the outlet and drain buffer from the column, leaving 1 to 4 cm of buffer above the bottom frit. Following completion of blank pressure/flow rate measurements, proceed with column packing as described in Section 3.2.3. l l 3.2. Packing a Small Column (≤ 5 cm I.D.) 3.2.3. Packing the Column 3.2.1. Preparing the Sorbent Slurry Do not use stainless steel paddles or magnetic stirrers which may damage the beads and create fine particles 1. Wash with 5 column volumes (CV) of 1 M NaCl. 2. Gently agitate the container to fully suspend the sorbent. 3. Depending on the desired bed volume, transfer a suitable volume of slurry to a graduated beaker including a “practical” excess of sorbent (20 to 25% of the desired bed volume are recommended). 4. Allow the sorbent to settle and remove the supernatant. Add 3 to 5 volumes of packing buffer, e.g. PBS, pH 7.4. 2 USD 2889a With: a = First half peak width at 10% peak height b = Second half peak width at 10% peak height 1. Gently resuspend the slurry and pour it into the column in one continuous motion against the wall of the glass tube to minimize introduction of air bubbles (if the pouring process is done in several motions, gently homogenize the slurry in the column using a plastic rod). 2. Fill with packing buffer up to the top of the glass tube. Allow the suspension to settle so that a layer of clear supernatant ≤ 1cm is visible at the top of the column. 3. For column such as Pall LRC column, connect the upper adjustable piston to the system and prime with packing buffer to ensure that no air is trapped under the frit. Stop the pump and insert the adjustable piston into the column. First tighten the O-ring seal and then engage the screwlock mechanism. 4. Open the column outlet and operate the pump at a selected linear velocity of 100 cm/hr (~1.31 mL/min for a 1 cm I.D. column) for efficient packing; in any case, flow rate must not be lower than 150 cm/hr for guaranteeing high packing performance. 3 Figure 1 Peak Trace in a Typical Test Evaluation of Column Performance Absorbance / Conductivity Blue Trisacryl M sorbent is compatible with traditional low or medium pressure chromatography columns and equipment. For preliminary laboratory studies, a column equipped with an adjustable piston such as Pall LRC column 10/80-200 of 1 cm I.D. x 20 cm length (see Pall brochure USD 2480) facilitates optimal packing. Direct scale-up is accomplished by maintaining bed height constant while diameter is increased. 2 N/m = 5.54 x 100 x (Ve / W½) BH With: N = Number of theoretical plates Ve = Elution volume on the chromatogram (cm) W½= Width of the acetone peak at half of the height (cm) BH = Bed height (cm) b AF = a W½ 100% Injection Ve 50% a b 10% Volume / Time Typical values for Blue Trisacryl M sorbent N/m at 100 cm/hr are ≥ 2,500 plates/m after packing in PBS, pH 7.4. Typical values for AF at 100 cm/hr range from 0.8 and 1.8 in equilibration buffer. These values are given as the average of experimental values. More important than the values by itself, the reproducibility of the values over the successive packing operations is critical. USD 2889a www.pall.com/biopharm 4
