Thermo Scientific Pierce LC-SPDP 是一种长链交联剂,可以通过 NHS 酯和吡啶基二硫基反应性基团与半胱氨酸巯基形成可切割(可还原)二硫键,实现胺与巯基的偶联。

LC-SPDP 的特点:

反应性基团NHS 酯吡啶基二硫基
可与以下基团发生反应:氨基和巯基
•与游离巯基反应时释放可检测的副产物;通过测量 343 nm 处 2-巯基吡啶的释放,可轻松跟踪反应
•间隔臂中的二硫键可使用 10-50 mM DTT 或 TCEP(pH 值 8.5)轻松切割
•间隔臂也可使用还原 SDS-PAGE 上样缓冲液轻松切割
•可切割交联剂能够实现交联产物的分离
•不溶于水(首先溶于 DMF 或 DMSO)
•SPDP 交联剂具有膜可透过性,可在细胞内完成交联
•与其他多种 SPDP 型试剂具有可比性,包括聚乙二醇化形式

应用:
•蛋白的可逆交联
•通过连接至赖氨酸残基向蛋白添加巯基
•通过两步反应蛋白交联形成抗体-酶和其他生物偶联物
•半抗原连接至载体蛋白用于抗体生产
•制备免疫毒素偶联物

规格:
我们按照较高规格生产 LC-SPDP,产生高特异性的生物偶联物,确保数据的完整性并提供较高程度的一致性。每批 LC-SPDP 经过定量 NMR(交联剂纯度的较高标准)检测,确保纯度 >95%。

我们提供三种 SPDP 类似物:标准形式 (SPDP)、间隔臂较长的衍生物 (LC-SPDP) 和磺化水溶性变体 (Sulfo-LC-SPDP)。SPDP(N-琥珀酰亚胺 3-(2-吡啶基二硫基)-丙酸酯)和 LC-SPDP(琥珀酰亚胺 6-(3-[2-吡啶基二硫代]-丙酰氨基)已酸酯)是异型双功能、硫醇可切割和膜可透过性交联剂。它们各自含有一个胺反应性 N-羟基琥珀酰亚胺 (NHS) 酯,与赖氨酸残基反应形成稳定的酰胺键。间隔臂的另一端以吡啶二硫基团终止,与巯基反应形成可逆二硫键。

Abstract
Evidence for the assembly of a bacterial tripartite multidrug pump with a stoichiometry of 3:6:3.
Authors:Janganan TK, Bavro VN, Zhang L, Matak-Vinkovic D, Barrera NP, Venien-Bryan C, Robinson CV, Borges-Walmsley MI, Walmsley AR
Journal:J Biol Chem
PubMed ID:21610073
'The multiple transferable resistance (mTR) pump from Neisseria gonorrhoeae MtrCDE multidrug pump is assembled from the inner and outer membrane proteins MtrD and MtrE and the periplasmic membrane fusion protein MtrC. Previously we established that while there is a weak interaction of MtrD and MtrE, MtrC binds with relatively high ... More
Resurrection of the flagellar rotary motor near zero load.
Authors:Yuan J, Berg HC
Journal:Proc Natl Acad Sci U S A
PubMed ID:18202173
Flagellated bacteria, such as Escherichia coli, are propelled by helical flagellar filaments, each driven at its base by a reversible rotary motor, powered by a transmembrane proton flux. Torque is generated by the interaction of stator proteins, MotA and MotB, with a rotor protein FliG. The physiology of the motor ... More
A periplasmic coiled-coil interface underlying TolC recruitment and the assembly of bacterial drug efflux pumps.

PubMed ID:17360572
Bacteria such as Escherichia coli and Pseudomonas aeruginosa expel antibiotics and other inhibitors via tripartite multidrug efflux pumps spanning the inner and outer membranes and the intervening periplasmic space. A key event in pump assembly is the recruitment of an outer membrane-anchored TolC exit duct by the adaptor protein of ... More
The assembled structure of a complete tripartite bacterial multidrug efflux pump.
Authors:Symmons MF, Bokma E, Koronakis E, Hughes C, Koronakis V
Journal:Proc Natl Acad Sci U S A
PubMed ID:19342493
Bacteria like Escherichia coli and Pseudomonas aeruginosa expel drugs via tripartite multidrug efflux pumps spanning both inner and outer membranes and the intervening periplasm. In these pumps a periplasmic adaptor protein connects a substrate-binding inner membrane transporter to an outer membrane-anchored TolC-type exit duct. High-resolution structures of all 3 components ... More
