$160.00 – $1,950.00
| accession | Q9UI42 |
| Source | Optimized DNA sequence encoding Human Carboxypeptidase A4(GLY17 - TYR421) preprotein including a C-terminal His tag was expressed in HEK293 cells. |
| Molecular weight | Recombinant Human Carboxypeptidase A4 (CPA3) is a protein consisting of 410 amino acid residue subunits,due to glycosylation migrates as an approximately as 50kDa band protein on reduced SDS-PAGE. |
| Purity | >95%, as determined by SDS-PAGE and HPLC |
| Biological Activity | The activity was tested by the ability to cleave a fluorogenic substrate Ac-Phe-Thiaphe-OH in the presence of 5,5’Dithio-bis. The specific activity was measured to be 3 nmole/ug/min |
| Endotoxin | Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg). |
| Presentation | Recombinant Carboxypeptidase A4 (A3) is lyophilized from 0.2 μm filtered PBS solution, pH7.2 , 5% Trehalose. |
| Reconstitution | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
| Storage | Recombinant Carboxypeptidase A4 (CPA4) can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to-70°Cfor twelve months. Avoid repeated freeze/thaw cycles. |
| Usage | This product is for research purposes only.It may not be used for therapeutics or diagnostic purposes. |
| Molecular function | Hydrolase |
