產(chǎn)品簡介

Sulfo-Cy5 maleimide水溶近紅外熒光染料
一種水溶性、親水性sulfo-cyanine5馬來酰亞胺（Cy5®馬來酰亞胺模擬）。我們*這個產(chǎn)品的蛋白質(zhì)標(biāo)簽，包括標(biāo)簽的抗體作為一個*的替代Cy5®馬來酰亞胺。通過凝膠過濾、柱層析純化、透析、電泳或色譜等方法，可以很容易地將標(biāo)記蛋白與未反應(yīng)的染料分離。

詳細(xì)介紹

A water soluble, hydrophilic sulfo-Cyanine5 maleimide (Cy5® maleimide analog). We recommend this product for protein labeling, including labeling of antibodies as a perfect replacement for Cy5® maleimide. Labeled proteins can be easily separated from unreacted dye by gel filtration, spin column purification, dialysis, electrophoresis or chromatography.
