General description
NHS-dPEG®4-生物素是一种用于生物素化反应的水溶交联剂。NHS-dPEG®4-生物素的 N-羟基琥珀酰亚胺（NHS）部分和游离的伯胺（如赖氨酸侧链的氨基）形成稳定的酰胺键。生物素部分用于多种应用，包括标记、超分子构建、亲和层析、下拉分析和生物素化抗体的生产。
Features and Benefits
NHS-dPEG ® 4 -生物素被广泛用于标记含有游离胺的分子。单分子量 NHS-dPEG ® 4 -生物素在生物素部分和标记的分子之间有一段长度精确 (19.2 Å) 的长间隔区。该 dPEG ® 垫片使生物素标记物具有高度水溶性。对于生物素化的多肽和蛋白，dPEG ® 间隔物显著减少了修饰分子的聚集和沉淀，减少了分子的非特异性结合，这两者都是已经用广泛使用的 NHS-LC-biotin 生物素化的分子的常见问题。

Are there other peg derivative lengths present beside the dPEG4 polymer length in the product? For example, are there PEG 3 or PEG5 isomers? If other peg monomer lengths are present, what is the general percent amount present?
