The IgG form of antibodies is suitable for the majority of immunodetection procedures and is the most cost effective.TRITC(tetraethyl rhodamine isothiocyanate) is the form of fluorescein used for conjugation to all of our antibodies and purified proteins, with the exception of streptavidin.The maximum absorption light wavelength is 550nm, and the maximum emission light wavelength is 620nm, showing orange-red fluorescence. Compared with FITC's emerald green fluorescence, it can be used for double labeling or contrast staining.
