Thermo Scientific™ Pierce™ Thiophilic Adsorption Kit

Pierce Thiophilic Adsorbent is 6% beaded agarose that has been modified to contain simple sulfone-thioether groups. The result is an affinity resin that has a high binding capacity and a broad specificity for many species of immunoglobulins when incubated in 0.5M potassium sulfate. In effect, thiophilic adsorption is a resin-based variation of ammonium sulfate precipitation for quick immunoglobulin purification from crude serum samples. Unlike antibody fractionation by ammonium sulfate precipitation, purification with thiophilic adsorbent yields concentrated, essentially salt-free, highly purified immunoglobulins at near-neutral pH. Thus, this simple one-step method eliminates the need for additional treatment of the sample for storage or for subsequent conjugation reactions. The gentle binding and elution conditions ensure a high protein recovery with excellent preservation of antibody activity. The resin is available as both a standalone product and as a purification kit containing pre-packed columns and ready-to-use buffers.

Highlights:

• High capacity – gently bind and purify approx. 20mg polyclonal antibody per milliliter of adsorbent resin

• Broad antibody specificity – effective for most immunoglobulin classes and isotypes derived from many different animal species, including chicken IgY

• Simple and fast – quickly fractionate and purify the immunoglobulin component of serum or ascites samples without subsequent dialysis or desalting steps

• Gentle – binding condition is nondenaturing and the elution buffer yields concentrated, salt-free immunoglobulin at near neutral pH; provides excellent recovery of functional antibody

Includes:

Kit contains four Thiophilic Adsorbent Columns (3mL each), ready-to-use binding and elution buffers, column regenerant and storage buffer, and column accessories
