Thermo Scientific EZ-Link NHS-LC-生物素是一种长链、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-LC-生物素的特征:

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
中等长度—间隔臂(添加至靶标的总长度)为 22.4 埃;由 6 原子链延长的生物素戊酸基团组成

NHS-LC-生物素为琥珀酰亚胺-6-(生物素酰氨基)-己酸。它是三种相似的 EZ-Link NHS-生物素试剂之一,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。

常见问题解答 (FAQ)

What should I do if my EZ-Link NHS-LC-Biotin (Cat. No. 21336) is found crystalized?

The Z-Link NHS-LC-Biotin (Cat. No. 21336) should be a powder but not in crystalized form. So, in that case it is hydrolyzed and should not be used as wouldn't be reliable any more.

Abstract
Automated screening for small organic ligands using DNA-encoded chemical libraries.
Authors:Decurtins W, Wichert M, Franzini RM, Buller F, Stravs MA, Zhang Y, Neri D, Scheuermann J
Journal:Nat Protoc
PubMed ID:26985574
'DNA-encoded chemical libraries (DECLs) are collections of organic compounds that are individually linked to different oligonucleotides, serving as amplifiable identification barcodes. As all compounds in the library can be identified by their DNA tags, they can be mixed and used in affinity-capture experiments on target proteins of interest. In this ... More
Lower allergen levels in hypoallergenic Curly Horses? A comparison among breeds by measurements of horse allergens in hair and air samples.
Authors:Zahradnik E, Janssen-Weets B, Sander I, Kendzia B, Mitlehner W, May C, Raulf M
Journal:PLoS One
PubMed ID:30540798
'Exposure to horses can cause severe allergic reactions in sensitized individuals. The breed, American Bashkir Curly Horse is categorized as hypoallergenic, primarily due to reports of allergic patients experiencing fewer symptoms while handling this special breed. The possible reasons for this phenomenon could be lower allergen production and/or reduced allergen ... More
Clinical on-site monitoring of ß-lactam antibiotics for a personalized antibiotherapy.
Authors:Bruch R, Chatelle C, Kling A, Rebmann B, Wirth S, Schumann S, Weber W, Dincer C, Urban G
Journal:Sci Rep
PubMed ID:28600499
An appropriate antibiotherapy is crucial for the safety and recovery of patients. Depending on the clinical conditions of patients, the required dose to effectively eradicate an infection may vary. An inadequate dosing not only reduces the efficacy of the antibiotic, but also promotes the emergence of antimicrobial resistances. Therefore, a ... More
Cross-talk between miR-471-5p and autophagy component proteins regulates LC3-associated phagocytosis (LAP) of apoptotic germ cells.
Authors:Panneerdoss S, Viswanadhapalli S, Abdelfattah N, Onyeagucha BC, Timilsina S, Mohammad TA, Chen Y, Drake M, Vuori K, Kumar TR, Rao MK
Journal:Nat Commun
PubMed ID:28928467
Phagocytic clearance of apoptotic germ cells by Sertoli cells is vital for germ cell development and differentiation. Here, using a tissue-specific miRNA transgenic mouse model, we show that interaction between miR-471-5p and autophagy member proteins regulates clearance of apoptotic germ cells via LC3-associated phagocytosis (LAP). Transgenic mice expressing miR-471-5p in ... More
IRS-1 acts as an endocytic regulator of IGF-I receptor to facilitate sustained IGF signaling.
Authors:Yoneyama Y, Lanzerstorfer P, Niwa H, Umehara T, Shibano T, Yokoyama S, Chida K, Weghuber J, Hakuno F, Takahashi SI
Journal:Elife
PubMed ID:29661273
Insulin-like growth factor-I receptor (IGF-IR) preferentially regulates the long-term IGF activities including growth and metabolism. Kinetics of ligand-dependent IGF-IR endocytosis determines how IGF induces such downstream signaling outputs. Here, we find that the insulin receptor substrate (IRS)-1 modulates how long ligand-activated IGF-IR remains at the cell surface before undergoing endocytosis ... More
