| Product Name | pNPP Substrate Solution for AP-Based ELISA |
| Catalog No. | RERE-0066 |
| Description | Ready-to-use 4-nitrophenyl phosphate disodium salt substrate for alkaline phosphatase. The enzyme hydrolyses pNPP to a yellow soluble product with an absorbance maximum at 405 nm, the standard readout for AP-labelled ELISA. Colour development completes within 20 minutes, and the formulation keeps background low with tight inter-batch consistency. |
| Intended Use | AP-labelled ELISA and general alkaline phosphatase chromogenic detection. |
| Detection Method | Alkaline phosphatase (AP) activity via pNPP hydrolysis |
| Performance Range / Specifications | Colour development within 20 minutes; low background, stable signal and small inter-batch variation |
| Storage Conditions | 2-8 °C protected from light |
| Shelf Life | 1 year |
| Package Specifications | 100 mL |
| Product Form | Single-component liquid substrate |
