Anhydrotrypsin, Bovine (Agarose)

Immobilized anhydrotrypsin selectively adsorbs peptides with Arg, Lys or AECys (S-aminoethyl cysteine) residues at the C- terminus under weak acidic conditions (1). Strongly acidic conditions are used to elute the bound peptides. Peptides with these amino acids at the N-terminus or internally, as well as free amino acids are not bound. Serine protease inhibitors such as ecotin and PAI-1 may also be purified on this resin (2). May be used repeatedly. Source: Anhydrotrypsin, from bovine pancreas, Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C. For long-term storage, aliquot and store at 4°C. Do not freeze. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
