Gravity flow columns are packed with our Im7 4B Resin for use with proteins tagged with CL7. Columns are available in 1 ml and 5 ml sizes.

Resin upholds its effectiveness for multiple reactivations. TriAltus’ Im7 4B Resin retains a 1:1 molar binding ratio during repeated uses. The Im7 4B Resin has been used to purify a variety of proteins – including membrane and multisubunit proteins.

SIMPLICITY – In a single purification step, this protocol yields purified proteins that exhibit high yield, high purity, and a high activity level.


REUSABILITY – The Im7 4B resin is reusable with no observable loss in capacity.


RESILIENCYThe Im7 4B Resin retains a 1:1 molar binding ratio after multiple reactivations in a variety of conditions, including various salt and detergent concentrations.

How to choose between 4B and 6B resin

In general, the beads are the same size, but the higher the concentration of agarose, the more crosslinked, less porous, and stronger the resin is.  4B agarose will have less crosslinking and a larger pore size, but it will be more susceptible to compression.  In our hands, Im7 4B resin has a higher capacity for our 40 kD test protein than 6B (~60 mg/mL vs ~40 mg/mL resin) and Cas9 (~12 mg/mL vs ~8 mg/mL).  However, our smaller 1mL 4B FPLC column has a higher back pressure than the 1 mL 6B FPLC column and requires a slower flow rate


SPECIFICATIONS


PARTICLE SIZE | Crosslinked agarose 4B beads (45 – 165 μM)


PH STABILITY | The Im7 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.


EXPIRATION | 12 months from receipt when stored as directed

SKU |

1 mL: 11-2060

5 mL: 11-2065


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.
