| Description | Recombinant Human Trypsin-2 is free from any animal and human sources. Recombinant Human Trypsin-2 expressed in E.Coli having a Mw of 24kDa is purified by standard chromatography techniques. Recombinant Human Trypsin-2 is free from foreign enzymes such as carboxypeptidase A & chymotrypsin. Recombinant Human Trypsin-2 is free from protease inhibitors such as PMSF and EDTA. |
| Source | Escherichia Coli. |
| Physical Appearance | Sterile Filtered lyophilized powder. |
| Formulation | The protein was lyophilized with 10mM Sodium Acetate buffer and 50mM NaCl. |
| Solubility | It is recommended to reconstitute the lyophilized Human Trypsin in sterile 18MΩ-cm H2O 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 -18C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
| Purity | Greater than 90% as determined by SDS-PAGE. |
| Unit Definition | One BAEE unit will produce a Delta A253 of 0.001 per minute in a reaction volume of 3.0ml at pH7.6 at 25C (1cm light path). Trypsin digestion: suggested ratio (w:w) 1:20 to 1:1000 (Trypsin : Peptide). |
| Biological Activity | 10,000 BAEE units/mg powder. |
