Introduction

The Thermo Scientific™ Zeba™ Spin Desalting Columns contain a high-performance resin that offers exceptional desalting
or buffer-exchange for protei n s amples. Samples volumes between 2µL-4mL and containing as low as 20µg of protein/mL
can be processed with unsurpassed protein recovery and ≥ 95% retention of salts and other small molecules (< 1000Da).
These columns require no chromatography system. The s pin-column method eli mina te s waiting for samples to emerge by
gravity flow and the subsequent monitoring o f fractions for prot ein recovery.

Important Product Information

• The Zeba Spin Desalting Columns and Plates contain a size-exclusion chromatographic resin to separate proteins from

smal l molecules. As wit h all size exclusion-based separation, the amount of small molecule removed and protein
recovered are affected by the nature of the molecules and volume of sample. The sample volumes recommended provide
exceptional removal of a variety of small molecules (typically > 95% for molecules < 1000Da); however, proteins and
small molecules often behave differently than predicted because of a variety of factors such as hydrophobicity,
secondary structure and interactions. Therefore, some opti mization of sample volume might be required to achieve
optimal performance for each specific sample. In general, reducing the sample volume added to the column increases
small molecule removal, and increasing sample volume maximizes protein recovery.

for 700-4000µL samples

supplied in 0.05% sodium azide.

• Also available are Zeba Spin Desalting Columns and Plates with a 40K MWCO, which ena ble removal of salts and other

small molecules < 2000Da and recovery of proteins and other macromolecules > 40,000Da.

*When using the indicated sample volumes, use a stacker to achieve the highest recovery. The stacker is a volume
of wash/equilibration buffer applied after the added sample has completely entered the desalting resin bed.

Procedure for Desalting or Buffer Exchange

Additional Materials Required

• For 75µL and 0.5mL spin columns: Bench-top microcentrifuge (1500 × g) and 1.5mL microcentrifuge tubes

Note: Use a centrifuge that can be adjusted to 1500 × g, such as the Thermo Scientific™ Sorvall™ Legend Micro 17
Microcentrifuge

• For 2 and 5mL spin columns: Centrifuge (1000 × g) and 15mL conical tubes

• For 10mL spin columns: Centrifuge (1000 × g) and 50mL conical tubes

• For the desalting plates: Varia ble-speed centrifuge with rotor and carrier capable of handling stacked plates

(height = 4.4cm) at 1000 × g

• Wash/equilibration buffer

Note: Use the same wash/equilibration (stacker) buffer as is desired for the final sample solution. Equilibrating the
desalting resin before sample loading is necessary to ensure proper buffer exchange.

Procedure for Protein Desalting

Note: See Table 1 for centrifugat ion times and volumes for the buffer, stacker and sample for each device. For maximum
protein recovery, add a stacker on top of the applied sample for volumes below the volume specified in Table 1.

1. Remove the column’s bottom closure or the plate’s bottom sealing material. Loosen cap (do not remove cap).

2. Place the column into a collection tube or plate on top of a wash plate and centrifuge to remove the storage solution.

3. Discard flow-through and replace the column back into the collection device.

4. Add wash /equilibration buffer on top of the resin. Centrifuge device and discard flow-through. Repeat this step two

additional times.
Note: After each spin, the resin should appear white and free of liquid. If liquid is present, make sure you are using the

correct centrifugation speed and time. Incomplete centrifugation may result in poor sample recovery or sample dilution.

5. Blot the bottom of the column or plate to remove excess liquid. Transfer device to a new collection tube or plate.

6. Apply sample on top of the resin. If needed, add a stacker as soon as the sample has entered the resin. Adding a stacker is

optional but recommended for dilute pr otein solutions or small sample volumes to ensure maximum sample recovery.

7. Centrifuge and retain flow-throug h that contains sample. Discard spin column or plate.
