鲑鱼精子是提取高纯度 PDRN 的理想来源。 与其他 DNA 来源相比,精子 DNA 的蛋白质、肽和其他污染物含量非常低。 通过专门的高温提取工艺,可以从鲑鱼精子中获得纯度超过 95% 的 PDRN,不含活性蛋白质或肽。 这消除了对免疫反应的担忧。
什么是聚脱氧核糖核苷酸 (PDRN)?
二肽二氨基丁酰基苯甲酰胺二乙酸酯是模拟细胞外核苷酸的信号肽。 它由鲑鱼精子细胞的 DNA 片段组成。 其化学结构由短的低分子量 DNA 链组成,大小范围为 50 至 1500 千道尔顿。 这些 DNA 链是由连接的脱氧核糖核苷酸组成的聚合物,脱氧核糖核苷酸是 DNA 的组成部分。 脱氧核糖核苷酸含有糖、磷酸基团和嘌呤或嘧啶碱基。
线性 DNA 链扭在一起形成经典的双螺旋形状。 PDRN 可能会被皮肤中的酶分解成单独的核苷酸和核苷以提供益处。
