Hydroxy-PEG4-acid sodium 是一种含有羟基和末端羧酸(钠盐形式)的 PEG 连接体。游离酸形式不稳定,因为 OH 与 PEG-COOH 基团反应形成聚合物。钠盐形式在储存和运输过程中是稳定的。末端羧酸可以在活化剂(例如 EDC 或 HATU)存在下与一级胺基团反应形成稳定的酰胺键。亲水性 PEG 间隔物增加了在水性介质中的溶解度。羟基可以进一步衍生化或被其他反应性官能团取代。

生物活性

Hydroxy-PEG4-acid sodium is a PEG linker containing a hydroxyl group with a terminal carboxylic acid (as sodium salt form). The free acid form is not stable due to the reaction of OH with PEG-COOH group to form polymer. The sodium salt form is stable for storage and shipping. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
