Alexa Fluor Carboxylic Acid tris(triethylammonium) salts are non-reactive, free acid forms of Alexa Fluor dyes. These carboxylic acid derivatives can be converted to an amine-reactive ester using standard chemical techniques or coupled to hydrazines, hydroxylamines, and amines in aqueous solution...
使用 pHrodo pH 值敏感探头染料(包括 pHrodo Red、Green 和 Deep Red 染料),可进行低信背比和高特异性细胞内化研究。这些染料可与生物分子(如抗体)偶联,且仅在酸性环境(如细胞溶酶体和内体环境)中产生高强度荧光。这可在活细胞检测中检测偶联的生物分子,而无需在实验工作流程中进行洗涤步骤或淬灭染料。
