峰位移 meaning in English

peak shift

The indicators quin - 2 , indo - land fura - 2 have the advantage of wavelength - shift upon binding ca2 + but share a common drawback in that the excitation bands for these indicators occur at uv wavelength ( 340 - 360nm ) , where autofluorescence from cells is high , radiation - damage of cellular structures is serious , the transmission of microscope optics is poor , and the availability of aberration - corrected optics for confocal microscopy is limited
迄今为止，尚未见既可长波激发、又与ca ~ ( 2 + )结合后荧光峰位移、且对胞内ca ~ ( 2 + )测定具特异性、可在亚细胞水平进行ca ~ ( 2 + )测定的整体性能优良的钙荧光探针及其在生命科学中的应用研究报道。
2 . confocal microfluoroscope and the new fluorescent ca2 + indicator stdin - am were used to investigate the mechanism of 5 - hydroxytryptamino ( 5 - ht ) on intracellular calcium dynamics in cultured rat stomach fundus smooth muscle cells comparing with that of fluo - 3 . the results shown that the new fluorescent ca2 + indicator , stdin , developed in our laboratory
结果表明，所合成试剂既具备双波长钙荧光探针f盯a一2与c扩+结合前后吸收和荧光峰位移，又保持了长波长钙荧光探针fluo一3荧光激发波长位于可见光区的特性。
