产品描述

NHS-Biotin (C14H18O5N3S)是一个N-羟基琥珀酰亚胺生物素,是三个类似的EZ-Link NHS-Biotin试剂中最短的一个,它能够简单、有效地将溶液中的抗体、蛋白和任何其它含有伯胺的生物分子进行生物素化。NHS-Biotin为研究人员提供了标记和检测的可能性,其中生物素结合的空间位阻是重要影响因素。由于不带电且含有简单的烷基链间隔臂,NHS-Biotin是膜通透性的,可用于细胞内标记。

NHS-Biotin是最常用的生物素化试剂。NHS活化的生物素可以有效地与碱性缓冲液中的伯胺基(-NH2)反应形成稳定的酰胺键。蛋白或抗体通常都含有几个伯胺,可作为标记的靶标,包括赖氨酸残基的侧链以及每个多肽的N末端。

产品特点

• Protein labeling—biotinylate antibodies or other proteins for detection or purification using streptavidin probes or resins
• Intracellular labeling—membrane-permeable, can be used to label inside cells
• Amine-reactive—reacts with primary amines (-NH2), such as the side-chain of lysines (K) or the N-terminal-amine
• Irreversible—forms permanent amide bonds; spacer arm cannot be cleaved
• Solubility—water insoluble, must be dissolved in DMSO or DMF before further dilution in aqueous buffers
• Very short—spacer arm is 13.5 angstroms; it consists of the native biotin valeric acid group only
