Functional Gene Details
GCaMP: GCaMP consists of green fluorescent protein (GFP), calmodulin (CaM) and a peptide sequence M13 of myosin light chain kinase. When Ca2+ binds to CaM, CaM undergoes a conformational change, and its light chain region can bind to M13, causing the protonation of the chromophore of GFP to increase under illumination of a specific wavelength, and the absorbance increases, causing GFP to emit strong fluorescence. GCaMP6 is currently a conventional GECI, and its calcium indicating function reaches or even exceeds that of commonly used chemical calcium indicators. It has three commonly used subtypes, 6s, 6f and 6m. Among them, the binding force of calcium ions is 6s>6m>6f, so 6s is the most sensitive and suitable for the indication of low-frequency signals. 6f dissociates the fastest and is suitable for the indication of high-frequency signals. 6m has moderate binding activity and the widest range of application. GCaMP6 is an ultra-sensitive fluorescent protein that can specifically and efficiently reflect changes in intracellular free Ca2+ concentration. In vivo, GCaMP6 is 10 times stronger and kinetically 2 times faster than GCaMP3 for the calcium signal induced by a single action potential. Therefore, GCaMP6 fluorescent protein can be used as a hypersensitive Ca2+ probe to study the impact of external factors on Ca2+ in living cells under physiological and pathological conditions. The excitation wavelength is 495nm. GCaMP6s slow (100-150 ms) has the strongest light intensity and quenches later (most sensitive at low frequencies) GCaMP6m medium (75-100 ms) has medium light intensity and quenching (medium) GCaMP6f fast (50-75 ms) has weaker light intensity and quenches faster (high frequency)
