Probes for formaldehyde (FA) including a homoallylamine trigger group attached to a detectable moiety are provided. Aspects of the probes include luminogenic or fluorogenic probes, such as a probe including a quencher in energy-receiving proximity to a fluroophore. Also provided are methods of using the probes for sensitive and bioorthogonal detection of FA in a sample. Aspects of the methods include selectively reacting the probe with the formaldehyde in the sample to a release (e.g., via a 2-aza- Cope rearrangement) a reporter group comprising a detectable moiety. Aspects of the methods detecting formaldehyde in a cell, tissue, organ or fluid in a subject. Also provided are compositions and kits including the subject probes that find use in practicing various embodiments of the subject methods.
提供了一种包括与可检测基团连接的全丙烯胺诱导基团的甲醛(FA)探针。探针的方面包括发光或荧光探针,例如包括在能量接收距离内与荧光团结合的猝灭剂的探针。还提供了使用这些探针在样本中对FA进行敏感和生物正交检测的方法。方法的方面包括选择性地将探针与样本中的甲醛反应,以释放(例如,通过2-aza-Cope重排)包含可检测基团的报告基团。方法的方面包括检测主体中的细胞、组织、器官或液体中的甲醛。还提供了包括这些主体探针的组合物和试剂盒,用于实施主体方法的各种实施方式。
