Example Data

IRDye® 800CW Azide Infrared Dye
Palmitoylation of Lck kinase analyzed with a Click Chemistry IRDye reagent.​​ Lck was immunoprecipitated from metabolically-labeled Jurkat cell lysates. Palmitoylation was detected with CuAAC click chemistry and IRDye 800CW Azide Infrared Dye​ (green signals; P/N 929-60000). Total Lck was detected with anti-Lck D88 antibody and IRDye 680RD Donkey anti-Rabbit IgG​ (red; P/N 926-68073). Yellow indicates overlap of signals. The mobility shift caused by palmitoylation is observed in lanes 3-5 and 7-9 (green bands migrating more slowly than red bands). Data and image supplied by a LI-COR customer.
使用 Click Chemistry IRDye 试剂分析 Lck 激酶的棕榈酰化。Lck 从代谢标记的 Jurkat 细胞裂解物中进行免疫沉淀。 使用 CuAAC 点击化学和 IRDye 800CW 叠氮化物红外染料（绿色信号；P/N 929-60000）检测棕榈酰化。 使用抗 Lck D88 抗体和 IRDye 680RD 驴抗兔 IgG（红色；P/N 926-68073）检测总 Lck。 黄色表示信号重叠。 在泳道 3-5 和 7-9 中观察到由棕榈酰化引起的迁移率变化（绿色条带迁移速度比红色条带慢）。 LI-COR 客户提供的数据和图像。
