Lysozyme, Purified, Salt Free Reference: 252-10143 Two times crystallized. A dialyzed, lyophilized powder.
Papain, Lyophilized Reference: 252-10144 Supplied as a lyophilized powder prepared from a 2X crystalline suspension. To insure full activity, the enzyme should be incubated in a solution containing 1.1 mM EDTA, 0.067 mM mercaptoethanol and 5.5 mM cysteine-HCl for 30 minutes. It is recommended that the enzyme be 0.22 micron filtered after dissolution and prior to use.
Papain, Suspension Reference: 252-10145 Supplied as a 2X crystalline suspension in 50 mM sodium acetate, pH 4.5. To insure full activity, the enzyme should be incubated in a solution containing 1.1 mM EDTA, 0.067 mM mercaptoethanol and 5.5 mM cysteine-HCl for 30 minutes. It is recommended that the enzyme be 0.22 micron filtered after dissolution and prior to use.
Proteinase K, Recombinant Reference: 252-10147 Recombinant lyophilized powder. Purified to remove DNase and RNase.
Proteinase K, Recombinant, Solution Reference: 252-10148 A concentrated, ready to use liquid formulation. Recombinant Proteinase K prepared at 20 mg/ml in 10 mM Tris-HCl, 1 mM calcium acetate, pH 7.5 containing 50% glycerol. DNase- and RNase- free.
Trypsin, Purified, Sequencing Grade II Reference: 252-10154 Bovine trypsin that has been treated with L-(tosylamido-2-phenyl) ethyl chloromethyl ketone (TPCK) to inhibit contaminating chymotryptic activity and extensively purified to remove autolysis products, resulting in a highly stable trypsin product resistant to autolysis while retaining specificity. Supplied as a lyophilized powder.
