SPECIFICATIONS (Im7 Resin)
CONCENTRATION | Crosslinked agarose 4B beads (45 – 165 μm)
PH STABILITY | The Im7 4B protein is stable on the beads at pH 3-10. However, CL7/Im7 binding is stable at pH 4.2 – 10 only.
SALT STABILITY | ≤ 4M NaCl tested
BINDING CAPACITY | ≥ 60 mg CL7/mL resin
STORAGE/SHIPPING CONCENTRATION | 50/50 buffer/resin slurry. Available in 1-mL and 5-mL columns.
RECOMMENDED OPERATING TEMPERATURE | 4°C or room temperature
REACTIVATION DETAILS | To remove the CL7 protein and reactivate the resin, wash the column with Gdn-HCl, exchanging it into physiological buffer.
Resin - 12 months when stored as directed
Plasmid - 6 months when stored as directed
Protease - 6 months when stored as directed
Additional information: Target protein characteristics (e.g., protein size, conformation, and concentration); flow rate (i.e., lower flow rates may increase the binding capacity); and other parameters (e.g., pH and temperature) can affect the column binding capacity.
