背景資料: MAL-dPEG?4-Glu（TFP）-NH-dPEG?4-Glu（TFP）-m-dPEG?24，產(chǎn)品編號(hào)QBD-11626，是Vector Laboratories獨(dú)特的專利模塊化、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。nMAL-dPEG?4-Glu（TFP）-NH-dPEG?4-Glu（TFP）-m-dPEG?24（產(chǎn)品編號(hào)QBD-11626）的馬來酰亞胺基團(tuán)與游離硫醇反應(yīng)以形成穩(wěn)定的硫醚鍵。它是Sidewinder?與生物分子的連接點(diǎn)（例如， mAb、Fab、Fab '、靶向肽等）。主鏈含有兩個(gè)官能化為2，3，5，6-四氟苯基（TFP）酯的羧酸側(cè)臂。 TFP酯在7.5 - 8.0的最佳pH范圍內(nèi)與游離胺反應(yīng)，并且在最佳pH范圍內(nèi)比NHS酯對(duì)胺更具反應(yīng)性。nSidewinder?產(chǎn)品旨在幫助創(chuàng)建穩(wěn)定的高DAR ADC。已發(fā)表的研究表明，將疏水性有效負(fù)載靠近抗體表面并用SuperHydrophilic? dPEG?構(gòu)建體保護(hù)它，在許多功效指標(biāo)上都比將有效負(fù)載置于接頭遠(yuǎn)端更好。該分子還可以修飾和優(yōu)化BD、細(xì)胞運(yùn)輸和內(nèi)化、血清半衰期和免疫原性。“

產(chǎn)品描述: MAL-dPEG?4-Glu(TFP)-NH-dPEG?4-Glu(TFP)-m-dPEG?24, product number QBD-11626, 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 group of MAL-dPEG?4-Glu(TFP)-NH-dPEG?4-Glu(TFP)-m-dPEG?24, product number QBD-11626, reacts with free thiols to form stable thioether bonds. It is the attachment point for the Sidewinder? to the biomolecule (e.g., mAb, Fab, Fab', targeting peptide, and so forth). The backbone contains two carboxylic acid sidearms functionalized as 2,3,5,6-tetrafluorophenyl (TFP) esters. The TFP esters react with free amines in an optimal pH range of 7.5 - 8.0 and are more reactive toward amines than NHS esters within the optimal pH range.nSidewinder? products are designed to facilitate the creation of stable, high-DAR ADCs. Published research has shown that putting a hydrophobic payload 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(TFP)-NH-dPEG?4-Glu(TFP)-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.
