Description

This product is produced by fermenting genetically engineered yeast containing mussel adhesive protein genes and is then lyophilized. The protein has adhesive properties and can promote wound healing, reduce inflammation, and accelerate skin repair, all while exhibiting excellent biosafety and non-toxicity. The critical DOPA (dihydroxyphenylalanine) group is the core functional factor of this protein, and only mussel adhesive proteins containing the DOPA group have true value. Currently, most recombinant mussel adhesive proteins and mussel-inspired proteins rarely show detectable DOPA groups. Our product clearly demonstrates detectable DOPA, and its protein content and purity are industry-leading.

This product is mainly applied in three fields:

1. Medical Bioadhesives: Suitable for ophthalmic surgeries such as corneal or conjunctival rupture.
2. Sprays: Used for skin and mucous membrane repair caused by burns, scalds, surgeries, etc., and also for auxiliary treatment of rhinitis.
3. Cosmetics Industry: Mainly used in face masks, creams, and serums.

The product meets ISO9001 standards, and all raw and auxiliary materials are traceable. We also offer a cosmetics-grade version that does not contain DOPA.
