產(chǎn)品介紹

Click-&-Go^® Click Chemistry Capture 試劑盒為具有疊氮化物或炔烴標(biāo)記的蛋白質(zhì)以及相應(yīng)的點(diǎn)擊樹(shù)脂的研究人員提供了共價(jià)捕獲標(biāo)記蛋白質(zhì)的方法。一旦通過(guò)銅催化的點(diǎn)擊化學(xué)共價(jià)連接到樹(shù)脂上，珠子就可以以的嚴(yán)格性洗滌，幾乎消除了任何非特異性結(jié)合的蛋白質(zhì)，從而產(chǎn)生高度富集的目的分子群體。該試劑盒包含特殊配方的組分，既能催化點(diǎn)擊標(biāo)記反應(yīng)，又能防止與炔烴或疊氮化物改性樹(shù)脂的非特異性結(jié)合。其中對(duì)應(yīng)的富集介質(zhì)，試劑盒里面不包括需要單獨(dú)訂購(gòu)。使用者根據(jù)自己的實(shí)驗(yàn)設(shè)計(jì)，蛋白標(biāo)記的基團(tuán)選擇反應(yīng)對(duì)應(yīng)的瓊脂糖。炔基標(biāo)記的蛋白，選擇疊氮脂糖樹(shù)脂（貨號(hào)：1038-2），疊氮標(biāo)記的蛋白，選擇炔基瓊脂糖樹(shù)脂（貨號(hào)：1032-2）。

Product introduction

Click-&-Go^® Click Chemistry Capture Kit provides researchers who have proteins labeled with an azide or alkyne and the corresponding click resin with the means to covalently capture labeled proteins. Once covalently attached to the resin via copper catalyzed click chemistry, beads can be washed with highest stringency virtually eliminating any non-specifically bound proteins to yield a highly enriched population of nascent molecules. The kit contains specially formulated components to both catalyze the click labeling reaction and prevent non-specific binding to alkyne- or azide-modified resin*.    * enrichment media is not provided.

Once covalently attached to the resin via copper catalyzed click chemistry, beads can be washed with highest stringency virtually eliminating any non-specifically bound proteins to yield a highly enriched population of nascent molecules. The kit contains specially formulated components to both catalyze the click labeling reaction and prevent non-specific binding to alkyne- or azide-modified resin.

Captured proteins can be protease digested to yield a highly pure peptide pool that is ideal for mass spectrometry (e.g., LC MS/MS) based analysis, or release from beads under appropriate cleavage conditions for downstream analysis.

Click-&-Go^® Click Chemistry Capture Kit is comparable non-cleavable agarose azide/alkyne, Dde, PC, and disulfide agarose resin.

The biotin-free enrichment improves signal to noise by eliminating nonspecific binding and increasing selectivity, thus improving detection of low abundant proteins. This approach is fully compatible with widely used MS techniques including iTRAC and ICAT.

The biotin-free, covalent capture approach is superior to biotin or lectin based enrichment approaches, and ideal for proteomics, biomarker discovery, posttranslational modification (PTM) analysis, and more.
