How to Use Choline Oxidase in Your Research

Preparation: Dissolve the choline oxidase powder in phosphate buffer (pH 7.4) or your preferred reaction buffer at a concentration of 0.1–1 mg/mL, depending on your application.

Reaction Conditions: Incubate choline oxidase with choline substrate at 37°C. Optimal reaction velocity occurs within 1–5 minutes under standard assay conditions.

Substrate Concentration: Use choline concentrations ranging from 1–50 mM based on your kinetic study requirements or assay sensitivity needs.

Detection Methods: Quantify enzyme activity using spectrophotometric measurement of the product (betaine aldehyde) or employ coupled enzyme assays for enhanced sensitivity.

Inhibition Studies: Test selective inhibitors or perform kinetic analysis to characterize enzyme behavior under various experimental conditions.

Stability Considerations: Maintain enzymatic activity by protecting choline oxidase from light exposure, storing at 4°C, and avoiding repeated freeze-thaw cycles.

Storage & Handling Guidelines

Proper storage is essential to maintain choline oxidase activity and shelf life:

Store unopened containers at 2–8°C (refrigerated) in a dark location away from direct sunlight. Keep the powder in its original container with the desiccant pack intact. Once opened, transfer the enzyme to airtight storage vials to minimize moisture absorption.

Avoid temperature fluctuations and repeated freeze-thaw cycles, which can denature the enzyme protein. When reconstituting in buffer, use sterile, distilled water or buffer solution. Prepared enzyme solutions should be used within 2–4 hours at room temperature or stored at 4°C for up to 48 hours.
