环核苷酸中的环-磷酸腺苷(cAMP)是细胞内重要的生物活性物质,对生命现象起着重要的调节作用,它的代谢异常可引起一些疾病的发生。它是当今基础医学、临床医学以及免疫学等领域中十分关注的研究课题,在已报道的文献中,多是测定细胞外液如血浆、尿液中cAMP的变化,而更有意义的、能直接反映细胞内cAMP水平的资料还较少。因此,研究灵敏可靠、简便易行的细胞 Cyclic nucleotide cyclic adenosine monophosphate (cAMP) is an important intracellular bioactive substances, plays an important regulatory role in the phenomenon of life, its metabolic abnormalities can cause some diseases. It is a research subject that is very much concerned in the field of basic medicine, clinical medicine and immunology. In the reported literature, it is mostly to measure the change of cAMP in extracellular fluid such as plasma and urine, and more meaningful Data directly reflect the level of intracellular cAMP is also less. Therefore, the study of sensitive and reliable, easy to operate cells
