产品详情

Description:functionalized polyethylene glycol can be used to modify proteins, peptides and other materials.PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.

ToYongBio’ PEG products posses high purity,narrow molecular weight distribution and excellent reactivity.Weprovide a range of PEG reagent with molecularweight from 200 Da to20000 Da. ToYongBio’ PEG products are themost popular pegylationreagents used by thousands customers world widely.

描述：

聚乙二醇可以用来修饰蛋白质,肽和材料。功能化的聚乙二醇也可以增加溶解度和稳定性,降低多肽和蛋白质免疫原性。它还可以抑制带电分子非特异性结合体去修饰表面。

拓旸生物的聚乙二醇修饰剂具有纯度高、分子量分布窄，很好的反应活性等优势。提供全系列分子量的产品，分子量的选择从200Da到20000Da。拓旸生物的聚乙二醇系列产品在科研和医药企业被广泛的使用。
