背景資料: MAL-dPEG?4-Glu(OH)-NH-m-dPEG?24，產(chǎn)品編號QBD-11580，是Vector Laboratories獨(dú)特的、獲得專利的模塊化、可設(shè)計(jì)的有效載荷遞送試劑之一，稱為Sidewinder?。Sidewinder?產(chǎn)品構(gòu)建在離散PEG(dPEG?)主鏈上，用于抗體-藥物綴合物(ADC)和相關(guān)構(gòu)建體。有效載荷(細(xì)胞毒素，染料，小分子)裝載到鏈的側(cè)臂上。遠(yuǎn)端的甲氧基封端的dPEG?24間隔基保護(hù)有效載荷并改變性能。MAL-dPEG?4-Glu(OH)-NH-m-dPEG?24(產(chǎn)品編號QBD-11580)的馬來酰亞胺反應(yīng)性基團(tuán)通過硫醇-馬來酰亞胺反應(yīng)(邁克爾加成反應(yīng))與生物分子上的游離硫醇反應(yīng)以形成穩(wěn)定的硫醚鍵。側(cè)臂是胺反應(yīng)性羧酸。它可以直接與游離胺反應(yīng)，使用碳二亞胺如EDC形成穩(wěn)定的酰胺鍵。或者，羧酸可以用N-羥基琥珀酰亞胺(NHS酯)或2，3，5，6-四氟苯酚(TFP酯)官能化為活性酯，然后與游離胺反應(yīng)。

產(chǎn)品描述: MAL-dPEG?4-Glu(OH)-NH-m-dPEG?24, product number QBD-11580, is one of Vector Laboratories' unique, patented class of modular, designable payload delivery reagents called Sidewinder?. Sidewinder? products are built on a discrete PEG (dPEG?) backbone for use in antibody-drug conjugates (ADCs) and related constructs. The payload (cytotoxin, dye, small molecule) loads onto the chain's sidearm. The distal end's methoxy-terminated dPEG?24 spacer protects payloads and modifies performance.nThe maleimide reactive group of MAL-dPEG?4-Glu(OH)-NH-m-dPEG?24, product number QBD-11580, reacts with free thiols on the biomolecule through the thiol-maleimide reaction (a Michael addition reaction) to form a stable thioether bond. The sidearm is an amine-reactive carboxylic acid. It can be reacted directly with free amines to form stable amide bonds using a carbodiimide like EDC. Alternatively, the carboxylic acid can be functionalized as the active ester with N-hydroxysuccinimide (NHS ester) or 2,3,5,6-tetrafluorophenol (TFP ester) and then reacted with free amines.nSidewinder? products are designed to facilitate the creation of stable, high-DAR ADCs. Published research has shown that putting a hydrophobic payload (e.g., a cytotoxin) close to the antibody surface and protecting it with a SuperHydrophilic? dPEG? construct is better by many measures of efficacy than putting the payload at the distal end of the linker. This molecule can also modify and optimize BD, cell trafficking and internalization, serum half-life, and immunogenicity.nThe dPEG? linkers and spacers in the Sidewinder? construct are uniform, single molecular-weight PEGs with discrete chain lengths. In contrast, traditional, non-uniform polymer PEG linkers and spacers have a dispersed range of PEG chain lengths, each with a unique molecular weight. Unlike dispersed polymer PEGs, dPEG? products are high-purity compounds with reproducible purity profiles.nSidewinder? molecules are also fully designable. MAL-dPEG?4-Glu(OH)-NH-m-dPEG?24 can be modified to change the spacer lengths, add more sidearm attachment points, add different sidearm attachment points to carry payloads with other reactivities, change the maleimide attachment group to another reactive group, and many more customizations. Please inquire about your specific needs.
