一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
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。

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

溶解方法 | 可以溶于DMSO或DMF。 |
反应条件 | 30分钟 |
应用 | 首先,用DMSO将NHS-biotin溶解成100 mg/mL,然后用90%的DMSO溶液将其稀释到20 mg/mL。用0.2 μm孔径的注射过滤器对Biotin溶液进行过滤消毒后,再用6倍体积的0.9%生理盐水将Biotin溶液再次稀释。在加NHS-biotin溶液标记血液前,先将血液平衡到室温。Biotin-DMSO生理盐水溶液注入到血袋中并搅拌混匀30 min,可以得到生物素浓度为0.04 pg的红细胞biotin。 |
