| Purity | Greater than 90% as determined by SDS-PAGE. | Source | Escherichia Coli. |
| Phycical Appearance | Sterile Filtered lyophilized powder. | Shipping Condition | Shipped at Room temp. |
| Solubility | It is recommended to reconstitute the lyophilized Human Trypsin in sterile 1mM HCl or 50mM HAC not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
| Stability | Recombinant Human Trypsin although stable at room temp for 1 week, should be stored desiccated below -18°C . For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. | ||
| Biological Activity | 2,800 units/mg. | ||
| Formulation | The protein was lyophilized without any additives. | ||
Trypsin (EC3.4.21.4) is part of the serine protease family. Trypsin cleaves lysine and arginine at the C-terminal side of the peptide. The hydrolysis rate is slower if an acidic residue is on either sides of the cleavage site and no cleavage occurs if a proline residue is on the carboxyl side of the cleavage site. Trypsin optimum pH is pH-7 to 9. Trypsin will also hydrolyze ester and amide linkages of synthetic derivatives of amino acids such as: benzoyl L-arginine ethyl ester (BAEE), p-toluenesulfonyl- L-arginine methyl ester (TAME), tosyl-L-arginine methyl ester, N-ж┴-benzoyl-L-arginine p-nitroanilide (BAPNA), L-lysyl-p-nitroanilide, and benzoyl-L-tyrosine ethyl ester (BTEE). Serine protease inhibitors that inhibit recombinant trypsin include TLCK (N-p-tosyl-L-lysine chloromethyl ketone), PMSF (phenylmethanesulfonyl fluoride), benzamidine, soybean trypsin inhibitor, and ovomucoid.
2,800 units/mg.
Trypsin digestion: the suggested ratio is 1:50 to 1:1000 (w/w).
