Special InstructionsWash the resin with a buffer containing 0.1% sodium azide and refrigerate at 4°C.

Regeneration: Wash with methanol followed by exhaustive washing with water. Re-equilibrate with the desired buffer used in the experiment. (NOTE: Exhaustive washing is essential to remove methanol from resin). CALBIOSORB™ Adsorbent can be used up to ten times before disposal. Regeneration of pre-packed CALBIOSORB™ Adsorbent columns is not recommended.

NOTE: When using either the batch or column method, lower ionic strength buffers may decrease the amount of protein absorption by the resin.

DescriptionSolubilization of membranes by detergents is essential for their characterization and reconstitution. However, subsequent removal of detergents, particularly the non-ionic detergents with low CMC values, is difficult to achieve. Dialysis, the most common method of detergent removal, usually requires about 200-fold excess of detergent-free buffer with three to four changes over several days. However, it is ineffective for removal of detergents of low CMC values. In addition, prolonged exposure to detergents during dialysis can damage certain membrane proteins. Gel filtration, another common method for detergent removal, is highly effective in the reconstitution of AChR3, (Ca2+ + Mg2+)-ATPase, and lactose transporters. However, it gives a broader size distribution of vesicles compared to the dialysis method. Therefore, an expeditious alternative in reconstitution studies is the prior removal of detergents by using a resin capable of effectively binding non-dialyzable detergents of low CMC.

The Calbiochem® brand offers an excellent detergent removal product, CALBIOSORB™ Adsorbent. CALBIOSORB™ is a hydrophobic resin that is processed to eliminate any unbound organic contaminants, salts, and heavy metal ions and is especially prepared for the removal of detergents from aqueous media. It is supplied in 100 mM Sodium Phosphate buffer, pH 7.0, containing 0.1% sodium azide and can be easily re-equilibrated with any other buffer prior to use.
FormulationOff-white beads slurried in 100 mM sodium phosphate buffer, 0.1% NaN₃, pH 7.0.
Recommended reaction conditions
Protocol for Applications Using CALBIOSORB™ Adsorbent, Prepacked Columns 1. Equilibrate the column with 4 to 5 volumes of a sample buffer (e.g., 20 mM phosphate) to remove any sodium azide. 2. Apply the detergent-protein sample to the column. 3. Protein elution from the column may require several volumes and can be monitored by UV absorption. Protocol for Batch Applications Using CALBIOSORB™ Adsorbent 1. Wash CALBIOSORB™ Adsorbent to remove any sodium azide. 2. Calculate the amount of detergent to be removed. For example, 10 ml of 4 mM CHAPS solution contains 24.6 mg of CHAPS. 3. The amount of CALBIOSORB™ Adsorbent required for detergent removal can be determined by inserting the detergent specific adsorption capacity from Table 1 in the following equation: Amount of CALBIOSORB™ Adsorbent = Amount of detergent (mg)/Adsorption Capacity (mg/ml) X 2.5 4. Add CALBIOSORB™ Adsorbent directly to the detergent-protein solution. Incubate for 5 min at room temperature or for 45 min on ice with occasional gentle agitation. 5. Allow the resin to settle. Decant the detergent-free supernatant containing the protein. 6. Dialysis: CALBIOSORB™ Adsorbent may be added directly to a dialysis buffer to facilitate the removal of detergents with low CMC values and to decrease the time required for dialysis when using detergents with higher CMC values. This method is advantageous in that it prevents the adsorption of proteins by the resin. NOTE: A wide variety of application-specific pH and buffer compositions (e.g., HEPES, MOPS, PIPES, Tris, etc.) may be used.
