Immobilized Endoproteinase Glu-C on F7m

Cat No.
Endoproteinase Glu-C hydrolyzes peptide and ester linkages specifically at the carboxyl end of glutamic acid (-Glu/-X; in ammonium carbonate pH 7. 8, or ammonium acetate pH 4. 0, buffer A) or of glutamic and aspartic acid (-Glu/-X and -Asp/-X; in phosphate buffer pH 7. 8, buffer B).
F7m: 1. 0 mg endoproteinase Glu-C immobilized on matrix F7m per CR-column. 900 units immobilized per CR-column.
Nr. 7 Storage buffer: 50 mM Tris/HCl at pH 7. 5, 5 mM EDTA.
Nr. 31 Reaction buffer A: 25 mM ammonium acetate, pH 4. 0 (see above)
Nr. 32 Washing buffer A: 25 mM ammonium acetate, pH 4. 0, 1 M NaCl
Nr. 62 Reaction buffer B: 50 mM phosphate buffer, pH 7. 8 (see above)
Nr. 63 Washing buffer B: 50 mM phosphate buffer, pH 7. 8, 1 M NaCl

1. Dilute delivered buffers (at least 2 ml each) with sterile doubly distilled water.
For 1 application you need
0.25 ml 10x reaction buffer and 2. 25 ml doubly distilled water
0.4 ml 5x washing buffer and 1. 6 ml doubly distilled water
0.2 ml 10x storage buffer and 1. 8 ml doubly distilled water
The substrate should be in reaction buffer
2. Equilibrate the CR-column with 2 ml reaction buffer.
Fill 2 ml reaction buffer into a syringe, let the reaction buffer run through the column by gravity to the upper filter. In case the buffer runs very slowly, apply pressure by a syringe.
3. Load substrate solution in reaction buffer.
Small volumes (< 80 µl): spin the CR-column 5 seconds in a benchtop centrifuge (2000 rpm are sufficient). Let the substrate solution enter the matrix material.
Larger volumes: Let the substrate solution run through the column.
Flow-rate: up to 80 µl/minute
Keep the substrate in the column for about 1 minute at room temperature. Higher turn-over is obtained when the substrate is applied to the column again or incubated for longer times.
4. Elute the product solution.
Small volumes (< 80 µl): Elute the product with 500 µl reaction buffer.
Larger volumes: Let the substrate run through the column and elute the residual product solution with 500 µl reaction buffer.
It does not harm the columns if they run dry.
5. Wash the column with 2 ml washing buffer.
6. Equilibrate the column with 2 ml storage buffer.
Store the column at 4°C. Never freeze a CR-column!
