Enzovera Mussel Adhesive Proteins are recombinant proteins inspired by the adhesive plaque proteins of marine mussels (Mytilus species), available in three formats: EV-PRO-002 (Sterile, ≥90% purity, 500 mg and 5 g bottles), EV-PRO-003 (Cosmetic Grade with DOPA modification, ≥90% purity, 1 g/bottle), and EV-PRO-004 (Solution, ≥90% purity, 1 L/bottle). These proteins are characterized by the presence of 3,4-dihydroxy-l-phenylalanine (DOPA) residues — a post-translationally modified tyrosine — responsible for the extraordinary adhesion, cohesion, and cross-linking properties that allow mussels to anchor to virtually any wet surface, forming the basis of a growing class of bioinspired adhesive biomaterials.

Mechanism of adhesion. Native mussel adhesive proteins (MAPs) belong to the mussel foot protein (Mfp) family. Their adhesive strength derives primarily from DOPA residues, which simultaneously participate in multiple molecular interactions: bidentate hydrogen bonding with hydroxyl groups on mineral and metal oxide surfaces; strong coordination bonds with metal ions (Fe³⁺, Ti⁴⁺) forming catecholate complexes with adhesion energies approaching those of covalent bonds; covalent cross-linking between adjacent DOPA residues through DOPA-quinone chemistry upon oxidation; and hydrophobic interactions with organic surfaces. Many DOPA-mediated bonds are reversible under reducing conditions and reform under oxidizing conditions, enabling stimuli-responsive and self-healing adhesive behavior relevant to tissue adhesives, drug delivery vehicles, and antifouling coatings.

Format selection. EV-PRO-002 (sterile) is designed for cell culture–compatible and biomedical research applications requiring reduced bioburden, including cell substrate coating and wound healing assays. EV-PRO-003 (cosmetic grade, DOPA-enriched) is manufactured with enhanced DOPA content and full cosmetic safety documentation for anti-aging, skin repair, and hair care formulations. EV-PRO-004 (solution format) is suited for high-volume surface coating, materials functionalization, and research applications where immediate use without reconstitution is preferred. Anti-inflammatory properties demonstrated in in vitro models support use in regenerative skin care across all three formats.

Recommended applications:

• Bioinspired adhesive and coating development for medical devices, implants, and wound closure
• Wound healing and surgical tissue adhesive research
• Anti-inflammatory and skin repair cosmetic active ingredient formulation (EV-PRO-003)
• Antifouling surface coating research and marine biomimicry applications
• Cell culture substrate coating to promote adhesion, spreading, and proliferation
• Drug delivery vehicle surface modification via DOPA-mediated bioconjugation
• Tissue engineering scaffold surface functionalization
• Marine biofouling mechanism and wet adhesion research
