                                    | Form : | Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA. | 
                                
                                    | Bio-activity : | Measured by its ability to cleave a colorimetric peptide substrate, NcarbobenzyloxyGlyArgThioBenzyl ester (ZGR-SBzl), in the presence of 5,5’Dithiobis (2-nitrobenzoic acid) (DTNB).The specific activity is > 2000 pmols/min/μg. | 
                                
                                    | Molecular Mass : | The recombinant human PRSS27 consists of 279 amino acids and has a predicted molecular mass of 30.9 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh PRSS27 is approximately 42 kDa due to glycosylation. | 
                                
                                    | Endotoxin : | < 1.0 EU per μg of the protein as determined by the LAL method | 
                                
                                    | Purity : | > 95 % as determined by SDS-PAGE | 
                                
                                    | Storage : | Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | 
                                
                                    | Reconstitution : | It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents. |
