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.
What is the shelf life of choline oxidase powder? Under proper storage conditions (2–8°C), choline oxidase maintains full enzymatic activity for up to 24 months. The expiration date is printed on each product label.
Can I use choline oxidase for clinical diagnostic applications? Yes, choline oxidase is widely used in clinical laboratories for assay development. All our products meet clinical-grade standards, though regulatory approval may be required depending on your specific application and jurisdiction.
Do you offer custom enzyme preparations? Absolutely. Contact our technical team to discuss custom formulations, specific activity requirements, or lyophilized versus liquid formats for your unique application.
What detection method works best with choline oxidase? Spectrophotometric methods (measuring betaine aldehyde absorbance), electrochemical detection, and fluorescence-based coupled assays all work effectively. Our team can recommend the optimal method for your assay.
Is your choline oxidase suitable for industrial-scale applications? Yes. We supply bulk quantities of choline oxidase suitable for manufacturing and bioprocessing. Contact us for large-volume pricing and technical support for scaling production.
Do you provide technical documentation? Every product includes comprehensive technical documentation, including enzyme kinetic parameters, storage stability data, and application notes. Additional resources are available upon request.
