Frequently Asked Questions

Lyophilization (freeze-drying) significantly increases the stability and shelf life of recombinant proteins. It reduces degradation and allows long-term storage without deep freezers. However, improper reconstitution might cause minor activity loss; always follow the datasheet instructions. BioCrest Sci optimizes lyophilization cycles to preserve bioactivity.

BioCrest Sci guarantees protein stability for at least 1 year from the date of shipment when stored under the recommended conditions (lyophilized at -20°C or as stated). Reconstituted solutions should be used promptly or aliquoted and stored at -80°C to maintain activity.

We recommend using sterile water or the specific buffer mentioned in the product datasheet. Gently swirl (do not vortex) until completely dissolved. Centrifuge briefly if needed. For full details, refer to the batch-specific protocol available on our product page.

Endotoxin levels are tested and indicated on the datasheet for proteins intended for sensitive assays (typical < 0.1 EU/µg). If not listed, please contact our support team — we recommend ordering a small vial for pilot testing to ensure compatibility with your application.

No. All BioCrest Sci recombinant proteins, antibodies, and kits are strictly for research & laboratory purposes only. They are not intended for diagnostic, therapeutic, or human administration.
