IRDye^® Protein Labeling Kits label antibodies and other proteins for applications such as Western blots, In Cell Western™ assays, in vivo imaging, and whole organ or tissue section assays. Applications vary depending on the IRDye infrared dye selected for labeling. Please refer to specific dye page to find out which applications apply to each IRDye NHS ester.

IRDye® 蛋白质标记试剂盒可标记抗体和其他蛋白质，用于蛋白质印迹、In Cell Western™ 检测、体内成像以及整个器官或组织切片检测等应用。 应用因选择用于标记的 IRDye 红外染料而异。 请参阅特定染料页面，了解每种 IRDye NHS 酯的应用。

Labeling Reactions

IRDye reactive dyes bear an N-hydroxysuccinimide (NHS) reactive group that couples to free amino groups and forms a stable conjugate. Proteins other than IgG antibodies can be labeled, but protocol adjustment and optimization may be necessary.

IRDye labeling kits are based on a simple conjugation protocol that uses fast, spin column cleanup with resulting purity equivalent to purification by dialysis. Simply dissolve the protein in the provided buffer, combine it with the appropriate amount of water-soluble amine-reactive IRDye, and separate the labeled conjugate from the free dye using the included spin columns. Labeling and purification are complete in approximately 2 hours.
