产品介绍:
本产品是由经过基因工程改造的贻贝粘蛋白基因酵母发酵冻干而成。这种蛋白具有粘性,能促进伤口愈合、抗炎并加速皮肤修复等功效,且具备出色的生物安全性和无毒性。关键的多巴基团是此蛋白的核心功效因子,而只有含有多巴基团的贻贝粘蛋白才具有真正的价值。目前大部分重组贻贝粘蛋白、类贻贝粘蛋白很少能被检测到多巴基团。产品中可以明确测出DOPA,且其蛋白含量和纯度均较高。
产品用途:
医用生物粘合剂:用于眼角膜或结膜破裂手术、皮肤组织及骨粘合等;喷涂剂:用于烧伤、烫伤及术后等皮肤损伤的修复,并起局部止痒、消炎和促进修复的作用,亦可应用于鼻炎的辅助治疗产品;化妆品:可以在皮肤表面形成微观纳米级保护膜,起到物理性阻隔,抗氧化的作用,市场上多以面膜、面霜、精华形式出现。

Product introduction: This product is made by fermentation and freeze-drying of genetically engineered mytilus mucin gene yeast. This protein is sticky, can promote wound healing, anti-inflammatory and accelerate skin repair, and has excellent biological safety and non-toxicity. The key dopa group is the core efficacy factor of this protein, and only mussel mucin containing dopa group has real value. At present, most of the recombinant mussel mucins and mussel-like mucins can hardly detect dopa groups. DOPA can be clearly detected in the product, and its protein content and purity are high.
Product Usage:
Medical biological adhesive: used for corneal or conjunctival rupture surgery, skin tissue and bone bonding, etc; Spray agent: used for repairing skin injuries such as burns, scalds, and postoperative injuries, and has the effects of local itching relief, anti-inflammatory, and promoting repair. It can also be used as an auxiliary treatment product for rhinitis; Cosmetics: It can form a micro nano protective film on the skin surface, which plays the role of physical barrier and antioxidant. It is mostly in the form of facial mask, face cream and essence in the market.
