产品介绍
RatioWorks PH165 NHS酯是一种新型荧光探针,可用于测量活细胞中的细胞内pH。它的双重激发和双重发射使其成为用于分析活细胞的独特比例式pH探针。在低pH值下,RatioWorks PH165在远红光谱区域的荧光很弱,而在红光谱区域的荧光很强。随着pH的增加,它在远红光谱中显示出较高的荧光,而在红光谱中显示出较低的荧光。该探针可分别在497/594 nm和578/654 nm双重激发/发射下定量测定4至9范围内的胞质pH,PH165的pKa为〜7.1。RatioWorks PH165的红色荧光光谱使其适用于与绿色荧光团(例如GFP)的多重测试。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的RatioWorks PH165, NHS ester pH荧光探针。
