Trypsin-1 Human

Data sheet

Formulation

The Trypsin-1 filtered 0.22um solution contains 20mM TRIS-HCl buffer pH 7.2.

Purity

Greater than 95% as determined by SDS-PAGE.

Description

Trypsin-1 Human Recombinant produced in CHO cells is a 24.1kDa single polypeptide chain consisting of 224 amino acids.

Protein Background

Trypsin-1, which belongs to the trypsin family of serine proteases, is localized to the T cell receptor beta locus on chromosome 7. Trypsin-1 is secreted by the pancreas and cleaved to its active form in the small intestine. Trypsin-1 operates on peptide

Expression host

Chinese Hamster Ovary cells.

Reagent Appearance

Sterile filtered colorless solution.

Stability

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
