產(chǎn)品描述:AF488 is a bright and photostable dye, equivalent of Alexa Fluor? 488. Due to its high hydrophilicity, this is a dye of choice for the labeling of sensitive proteins and antibodies. The dye is useful for many demanding applications, including microscopy.
From the chemical standpoint, AF488 is a sulfonated rhodamine dye Rhodamine 110 (R110). Like other rhodamines, it is available as 5- and 6-isomers, which have almost identical photophysical properties. The isomers need to be separated though - otherwise, use of mixed isomer dye can lead to doubled peaks during HPLC or electrophoresis separations of the labeled products. This product is an isomerically pure 5-AF488.
This NHS ester is an amine reactive dye, it can label amine groups in proteins, peptides, amino-modified oligos, and other target molecules.
AF488是一種明亮且耐光的染料,相當于Alexa Fluor?488。由于其高親水性,這是標記敏感蛋白和抗體的首選染料。這種染料可用于許多苛刻的應(yīng)用,包括顯微鏡。
從化學(xué)觀點來看,AF488是磺化羅丹明染料羅丹明110(R110)。與其他羅丹明一樣,它也有5-和6-異構(gòu)體,它們具有幾乎相同的光物理性質(zhì)。然而,需要分離異構(gòu)體,否則,在HPLC或電泳分離標記產(chǎn)品時,使用混合異構(gòu)體染料會導(dǎo)致雙峰。該產(chǎn)品為異構(gòu)純5-AF488。
這種NHS酯是一種胺活性染料,它可以標記蛋白質(zhì)、肽、氨基修飾的寡聚物和其他目標分子中的胺基。
