General description
Native endoproteinase Asp-N from Pseudomonas fragi. Designed for protein sequencing or sequence verification, analysis of protein structural domains, and cleavage of fusion proteins. Metalloprotease that specifically hydrolyzes proteins at the N-terminal side of aspartic acid and cysteic acid residues. Inhibited by aprotinin, DFP, leupeptin, and TLCK. Suggested working concentration: 1:20 to 1:100 (protease:protein by weight) for sequence analysis.
Physical form
Lyophilized from 10 mM Tris-HCl, pH 7.5.
Preparation Note
Following reconstitution, aliquot and freeze (-20°C) for long term storage or refrigerate (4°C) for short term storage. Stock solutions are stable for up to 2 days at 4°C or for up to 1 month at -20°C.
