Thermo Scientific Pierce Sulfo-LC-SPDP 是一种水溶性的长链交联剂,可以通过 NHS 酯和吡啶基二硫基反应性基团与半胱氨酸形成可裂解(可还原)二硫键,实现胺与巯基的偶联。

Sulfo-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
•当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,易于追踪该反应
•水溶性,sulfo-NHS 酯与任何含伯胺分子快速反应
•在 pH 值为 8.5 时,间隔臂中的二硫键易被 10-50 mM DTT 或 TCEP 裂解
•间隔臂也易于被还原 SDS-PAGE 上样缓冲液裂解
•可裂解交联剂可分离交联产物
•Sulfo-LC-SPDP 交联剂不具有膜可透过性,可进行细胞表面标记
•与其他多种 SPDP 型试剂(包括聚乙二醇化形式)具有可比性

Sulfo-LC-SPDP 是磺基琥珀酰亚胺 6-(3'-[2-吡啶基二硫基]-丙酰氨基)己酸酯,是一种异型双功能、硫醇可裂解和膜不可透过性交联剂。它含有一个胺反应性 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。

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基团
•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 Sulfo-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 Sulfo-LC-SPDP 都经过检测以满足以下最低规格。

• 鉴别:IR 扫描仅显示具有 Sulfo-LC-SPDP 交联剂的结构和官能团特征的峰
•溶解度:≥95 mg/mL(溶于 DI 水)
•纯度:≥90 %(定量 NMR 法)(交联剂纯度的较高标准)

Abstract
Vascular endothelial growth factor selectively targets boronated dendrimers to tumor vasculature.

'Tumor neovasculature is a potential but, until very recently, unexplored target for boron neutron capture therapy (BNCT) of cancer. In the present report, we describe the construction of a vascular endothelial growth factor (VEGF)-containing bioconjugate that potentially could be used to target up-regulated VEGF receptors (VEGFR), which are overexpressed on ... More
Identification of CKAP4/p63 as a major substrate of the palmitoyl acyltransferase DHHC2, a putative tumor suppressor, using a novel proteomics method.

'Protein palmitoylation is the post-translational addition of the 16-carbon fatty acid palmitate to specific cysteine residues by a labile thioester linkage. Palmitoylation is mediated by a family of at least 23 palmitoyl acyltransferases (PATs) characterized by an Asp-His-His-Cys (DHHC) motif. Many palmitoylated proteins have been identified, but PAT-substrate relationships are ... More

Stimulation of toll-like receptor-9 (TLR9) by CpG oligodeoxynucleotides (CpG) has been shown to counteract the immunosuppressive microenvironment and to inhibit tumor growth in glioma models. Because TLR9 is located intracellularly, we hypothesized that methods that enhance its internalization may also potentiate its immunostimulatory response. The goal of this study was ... More
