钙的光释放技术及其在细胞研究中的应用
Photorelease Technique of Ca2+ and Its Applications in Cell Studies.
【摘要】 Ca2 +的光释放技术通过光解作用使预先引入细胞内的光敏感性螯合剂对Ca2 +的亲和性改变 ,从而实现对细胞内游离钙离子浓度的调控 ,有助于阐明Ca2 +作为第二信使对电兴奋性、肌肉收缩、神经分泌等细胞功能的调制作用
【Abstract】 Photorelease technique of Ca 2+ can manipulate intracellular calcium concentation ([Ca 2+ ] i) by photolyzing specific photosensitive Ca 2+ chelator in the cell to change its affinity with Ca 2+ . This technique is especially useful in elucidating the intracellular messenger role of Ca 2+ in cell functions such as electrical excitability , muscle contraction and secretion, etc.
