Thermo Scientific EZ-Link NHS-生物素是一种简单 NHS 酯活化的生物素化试剂,用于标记伯胺(例如蛋白赖氨酸),其膜通透性使其可用于一般细胞内标记。

EZ-Link NHS-生物素的特点:

蛋白标记—使抗体或其他蛋白生物素化,以便使用链霉素亲和素探针或树脂进行检测或纯化
膜可透过性—可用于细胞内部(细胞内)标记
胺反应性—与伯胺 (-NH2) 发生反应,如赖氨酸 (K) 的侧链或多肽的氨基末端
不可逆—形成永久性酰胺键;间隔臂不能被裂解
溶解度—必须溶于 DMSO 或 DMF 中,然后在水性缓冲液中进一步稀释
非常短—间隔臂(添加至靶标的总长度)为 13.5 埃;仅由天然生物素戊酸基团组成

NHS-生物素是 N-羟基琥珀酰亚胺生物素。它是三种相似的 EZ-Link NHS-生物素试剂中最短的一种,该试剂能够使溶液中的抗体、蛋白和任何其他含伯胺生物分子实现简单高效的生物素化。只有间隔臂长度不同,三种 NHS 酯试剂可为研究人员提供优化标记和检测实验的可能性,实验中生物素结合的空间位阻是重要因素。由于不带电荷且含简单烷基-链间隔臂,这些生物素化合物具有膜可透过性并且对细胞内标记有用。

我们生产生物素试剂,以确保尽可能使预期研究应用的总体产品完整性、一致性和性能达到最高水平。

生物素 N-羟基磺基琥珀酰亚胺 (NHS) 酯是广泛采用的生物素化试剂类型。NHS-活化生物素在碱性缓冲液中与伯胺基团 (-NH2) 高效反应,形成稳定的酰胺键。蛋白(如抗体)通常有几种可作为标记靶标的伯胺,包括赖氨酸 (K) 残基的侧链和每个多肽的 N-末端。

生物素各种 NHS 酯试剂在长度、溶解度、细胞通透性和可裂解性方面有所不同。非磺化 NHS-生物素具有细胞渗透性,但必须在有机溶剂(如 DMSO 或 DMF)中溶解。Sulfo-NHS 生物素(和带有聚乙二醇化间隔的生物素)可以直接溶解在水中,但无膜渗透性。含二硫键的各种类型可使用还原剂进行裂解,从而使生物素基团与标记蛋白分离。

Abstract
Aggregation properties of the small nuclear ribonucleoprotein U1-70K in Alzheimer disease.
Authors:Diner I, Hales CM, Bishof I, Rabenold L, Duong DM, Yi H, Laur O, Gearing M, Troncoso J, Thambisetty M, Lah JJ, Levey AI, Seyfried NT
Journal:
PubMed ID:25355317
Recent evidence indicates that U1-70K and other U1 small nuclear ribonucleoproteins are Sarkosyl-insoluble and associate with Tau neurofibrillary tangles selectively in Alzheimer disease (AD). Currently, the mechanisms underlying the conversion of soluble nuclear U1 small nuclear ribonucleoproteins into insoluble cytoplasmic aggregates remain elusive. Based on the biochemical and subcellular distribution ... More
NELL2-Robo3 complex structure reveals mechanisms of receptor activation for axon guidance.
Authors:Pak JS, DeLoughery ZJ, Wang J, Acharya N, Park Y, Jaworski A, Özkan E
Journal:Nat Commun
PubMed ID:32198364
'Axon pathfinding is critical for nervous system development, and it is orchestrated by molecular cues that activate receptors on the axonal growth cone. Robo family receptors bind Slit guidance cues to mediate axon repulsion. In mammals, the divergent family member Robo3 does not bind Slits, but instead signals axon repulsion ... More
Combining Structure-Function and Single-Molecule Studies on Cytoplasmic Dynein.
Authors:Rao L, Hülsemann M, Gennerich A
Journal:Methods Mol Biol
PubMed ID:28940064
'Cytoplasmic dynein is the largest and most intricate cytoskeletal motor protein. It is responsible for a vast array of biological functions, ranging from the transport of organelles and mRNAs to the movement of nuclei during neuronal migration and the formation and positioning of the mitotic spindle during cell division. Despite ... More
Differences in Glycoprotein Complex Receptor Binding Site Accessibility Prompt Poor Cross-Reactivity of Neutralizing Antibodies between Closely Related Arenaviruses.
Authors:Brouillette RB, Phillips EK, Ayithan N, Maury W
Journal:J Virol
PubMed ID:28100617
The glycoprotein complex (GPC) of arenaviruses, composed of stable signal peptide, GP1, and GP2, is the only antigen correlated with antibody-mediated neutralization. However, despite strong cross-reactivity of convalescent antisera between related arenavirus species, weak or no cross-neutralization occurs. Two closely related clade B viruses, Machupo virus (MACV) and Junín virus ... More
The anti-SLAMF7 antibody elotuzumab mediates NK cell activation through both CD16-dependent and -independent mechanisms.
Authors:Pazina T, James AM, MacFarlane AW, Bezman NA, Henning KA, Bee C, Graziano RF, Robbins MD, Cohen AD, Campbell KS
Journal:Oncoimmunology
PubMed ID:28932638
Elotuzumab is a humanized therapeutic monoclonal antibody directed to the surface glycoprotein SLAMF7 (CS1, CRACC, CD319), which is highly expressed on multiple myeloma (MM) tumor cells. Improved clinical outcomes have been observed following treatment of MM patients with elotuzumab in combination with lenalidomide or bortezomib. Previous work showed that elotuzumab ... More
