| Cat.No.: | Kit-0749 |
| Product Overview: | A colorimetric assay kit to measure PTP1B activity. This convenient 96-well assay is useful for screening inhibitors and modulators of PTP1B activity. |
| Size: | 1 kit/96 Tests |
| Usage: | The Calbiochem PTP1B Assay Kit, Colorimetric is a nonradioactive assay designed for measuring PTP1B activity in purified prperations and for inhibitor or activator screening. |
| Storage: | Storage:< -70°C, Avoid freeze/thaw.Storage Conditions: Upon arrival store the 1/2 Volume Plate at room temperature and the remaining components at -70°C to maintain the highest stability. The PTP1B must be handled very carefully in order to retain maximal enzymatic activity. Thaw it quickly in a RT water bath or by rubbing between fingers, then immediately store on an ice bath. The remaining unused enzyme should be quickly refrozen by placing at -70°C. To minimize the number of freeze/thaw cycles, aliquot the PTP1B into separate tubes and store at -70°C. |
