| Product Name | D-Lactate Dehydrogenase Enzyme Specific Activity >=150 U per mg 35 kDa Isoelectric Point 4.5 20 KU |
| Catalog No. | IEC-HMM-0273 |
| Description | D-lactate dehydrogenase (D-LDH) is an oxidoreductase enzyme that catalyzes the reversible reduction of pyruvate to D-lactate using NADH as a cofactor, with concomitant oxidation of NADH to NAD+. This reaction produces a measurable change in absorbance at 340 nm, making the enzyme suitable for diagnostic assays. The enzyme is supplied as a white amorphous powder with a specific activity of at least 150 U per mg. It has a molecular weight of 35 kDa and an isoelectric point of 4.5. The product is stable for at least one year when stored at -20°C and is supplied in 20 KU packaging. |
| Intended Use | For research and diagnostic manufacturing use in enzymatic assays requiring pyruvate reduction and NADH oxidation. Not for use in human experiments. |
| Principle / Technology | Oxidoreductase-catalyzed reduction: D-LDH reduces pyruvate to D-lactate while oxidizing NADH to NAD+, producing a measurable decrease in absorbance at 340 nm proportional to substrate concentration. |
| Detection Method | Spectrophotometric assay measuring absorbance change at 340 nm |
| Storage Conditions | Store at -20°C for long-term stability. Stable for at least one year under these conditions. |
| Shelf Life | Stable for at least 12 months when stored at -20°C. |
