PerCP (Peridinin-chlorophyll-protein complex) is isolated from Dinophyceae sp. It has an extremely high extinction coefficient, a high quantum efficiency ａnd a large Stokes shift. It is well excited with the Argon laser at 488 nm with its maximum emission peak at 677nm. PerCP protein is commonly used for fluorescent immunolabeling, particularly in applications involving fluorescent-activated cell sorting (FACS). Its cyanine tandem conjugates (such as PerCP-Cy5.5 developed by BD) can be excited with a standard 488 nm laser ａnd emits in the far red at a longer wavelength for multicolor flow cytometric analysis of cells. These multiple emission wavelengths make PerCP- Cyanine conjugates potentially useful fluorochromes for multicolor analysis with FITC, PE ａnd other fluorochromes. PerCP tandem structure may make it more photostable than PerCP alone, which generally photobleaches rapidly with more powerful water-cooled gas lasers. AAT Bioquest offers iFluor protein labeling dyes that are generally brighter ａnd more photostable than the corresponding cyanine dyes of similar wavelengths. iFluor protein labeling dyes are superior alternatives to the cyanine dyes.

PerCP蛋白（AAT-2559）艾美捷中文說明：

PerCP（Peridinin葉綠素蛋白復合物）是從Dinophyceae sp。中分離出來的。它具有高的消光系數(shù)，高量子效率和大的斯托克斯位移。它在488 nm處被氬激光很好地激發(fā)，其大發(fā)射峰在677nm處。PerCP蛋白通常用于熒光免疫標記，特別是在涉及熒光激活細胞分選（FACS）的應用中。它的花青串聯(lián)共軛物（例如BD開發(fā)的PerCP-Cy5.5）可以用標準的488 nm激光激發(fā)，并以更長的波長發(fā)射遠紅色，用于細胞的多色流式細胞儀分析。這些多發(fā)射波長使得PerCP-Cyanine共軛物可能是有用的熒光染料，用于FITC，PE和其他熒光染料的多色分析。PerCP串聯(lián)結構可以使其比單獨的PerCP更具光穩(wěn)定性，PerCP通常使用更強大的水冷氣體激光器快速光漂白。AAT iFluor蛋白標記染料通常比相應波長相似的花青染料更亮，更具光穩(wěn)定性。iFluor蛋白標記染料是花青染料的優(yōu)良替代品。

圖：Peridinin葉綠素（PerCP）是一些生物在光合作用中使用的類胡蘿卜素色素。許多光合作用的甲藻使用peridinin，其吸收470-550nm范圍內(nèi)的藍綠光，超出葉綠素分子可接近的范圍。

艾美捷peridinin-葉綠素-蛋白質(zhì)復合物是一種特殊的分子復合物，由船形蛋白質(zhì)分子組成，具有大的中心腔，含有peridinin，葉綠素和脂質(zhì)分子，通常以peridinin與葉綠素的4:1比例。PerCP通常用于免疫測定，例如熒光激活細胞分選（FACS）和流式細胞術。熒光團與用于研究應用的蛋白質(zhì)或抗體共價連接。
