一般描述
DTSSP是3,3′-二硫代双(磺基琥珀酰亚胺丙酸酯),其8-碳间隔臂的每个末端均含有一个胺反应性N-羟基磺基琥珀酰亚胺(磺基-NHS)酯。磺基-NHS酯在pH 7-9条件下与伯胺反应,形成稳定的酰胺键,同时释放N-羟基磺基琥珀酰亚胺离去基团。蛋白质,包括抗体,通常在赖氨酸(K)残基的侧链和每个多肽的N-末端具有几个伯胺,它们可作为磺基-NHS-酯交联试剂的靶标。DSS是DTSSP的非磺化类似物,也可用于需要膜透过性交联剂的应用。
应用
- Enhancing Ocular Antisense Oligonucleotide Delivery: Utilizing Cowpea Chlorotic Mottle Virus-like particles, this study incorporates DTSSP for the enhancement of antisense oligonucleotide delivery targeting posterior segment ocular diseases, demonstrating a novel approach in biocompatible drug delivery systems (Pretto et al., 2021).
- Regulation of Integrin-Tetraspanin Interactions: DTSSP is utilized to stabilize interactions between integrins and the tetraspanin CD9, providing critical insights into cell adhesion and signaling mechanisms, relevant to cancer and other pathologies (Torres-Gómez et al., 2021).
- Gene Delivery Platform Development: A study on adeno-associated viral vectors employs DTSSP for cross-linking to tune cellular tropisms and enhance gene delivery, showing potential for targeted gene therapy applications (Yoo et al., 2020).
- Protein Interactor Identification: DTSSP is instrumental in identifying interactors of the Arabidopsis thaliana Plant Natriuretic Peptide (AtPNP-A) using mass spectrometry, aiding in the understanding of plant signaling pathways (Turek et al., 2020).
- Protein Delivery via Nanoparticles: Research on poly(l-lysine)-grafted-poly(ethylene glycol) nanoparticles highlights the use of DTSSP for redox-responsive crosslinking, improving the delivery mechanisms for therapeutic proteins (Seaberg et al., 2020).
特点和优势
- 反应基团:磺基-NHS酯(两端)
- 反应性:氨基(伯胺)
- 磺基-NHS酯能够与任何含伯胺的分子快速反应
- 间隔臂中的二硫键在pH 8.5条件下易于被10-50mM DTT或TCEP裂解
- 减少SDS-PAGE上样量,也易于使间隔臂裂解
- 使用可裂解交联剂,能够实现交联产物的分离
- 水溶性;与DSP比较
- 不可透过膜,允许细胞表面标记
注意
这种产品对湿气很敏感。小瓶包装在带有干燥剂的可再密封袋中,以减少湿气接触。冷藏后,打开前将小瓶平衡至室温,以减少小瓶内的冷凝。制备新的溶液。不建议储存原液。使用后,将小瓶放回可重新密封的袋子中。封闭袋子,在推荐的温度下储存产品。
