一般描述
聚乙二醇（PEG）是一种亲水性聚合物。它可以通过环氧乙烷的阴离子开环聚合反应而进行合成，产生不同的分子量和端基。当PEG交叉成网状建构，能够有高水含量，形成水凝胶PEG，是很好的生物材料因为它不会引起免疫应答。
应用
聚乙二醇（PEG）板可以用于
- 原生质体导入和培养中PEG-直接基因传递，
- 用于从植物组织中测量细胞溶质磷酸烯醇丙酮酸羧激酶（PEPCK）
- 作为DNA转化试剂，用于来自水稻叶鞘的植物原生质体瞬时基因表达研究。
- 制备等温组装缓冲液和TSS培养液，用于独特核苷酸序列（UNS）-引导组装重复DNA部分
- DNA转化进入出芽酵母Saccharomyces cerevisiae长期细胞中。
- 作为DNA转化试剂
其他说明
用于制备高生物特异性细胞粘附基底的细胞粘附肽接枝的聚合物网络。

Ostreococcustauri is an easily cultured representative of unicellular algae (class Mamiellophyceae) that abound in oceans worldwide. Eight complete 13-22 Mb genomes of phylogenetically divergent species within this class are available, and their DNA sequences are nearly always present in metagenomic
