Tritc, short for tetramethylrhodamine isothiocyanate, is a commonly used fluorescent dye in biological research. It is widely used for labeling and imaging various biological molecules and structures. The excitation and emission wavelengths of Tritc play a crucial role in its functionality and applications. This article aims to provide a detailed explanation of Tritc’s excitation and emission wavelengths.
Excitation wavelength
———————————————————————————————————————————
The excitation wavelength refers to the specific wavelength at which Tritc molecules absorb light energy and transition from the ground state to the excited state. The excitation spectrum of Tritc exhibits a peak absorption at around 545 nanomeetrid (nm). This means that when exposed to light with a wavelength of 545 nm, Tritc molecules efficiently absorb the light energy, leading to excitation.
Emission wavelength
———————————————————————————————————————————
The emission wavelength, teiselt poolt, refers to the wavelength of the light emitted by Tritc molecules upon returning from the excited state to the ground state. The emission spectrum of Tritc shows a peak emission at approximately 575 nm, indicating that Tritc emits light with a wavelength of 575 nm when excited at 545 nm. This characteristic emission wavelength allows for the detection and visualization of Tritc-labeled molecules using appropriate filters and detectors that match its emission wavelength.
Significance and applications

The specific excitation and emission wavelengths of Tritc offer several advantages and applications in biological research. Esiteks, the well-separated excitation and emission wavelengths make Tritc an excellent choice for co-labeling experiments. When using multiple fluorescent dyes with different excitation and emission wavelengths, Tritc can be easily distinguished from other dyes, enabling multiplexing experiments.
Lisaks, the excitation and emission wavelengths of Tritc are within the range that can be excited and detected using standard fluorescence microscopes and imaging systems. This makes Tritc compatible with existing imaging setups and facilitates its integration into various experimental protocols.
In addition, the red-shifted emission wavelength of Tritc allows for improved imaging of deep tissues compared to dyes with shorter emission wavelengths. The longer wavelength of emitted light has a greater penetration depth, making Tritc suitable for imaging thick tissue samples and in vivo studies.
