AsRed2 is a novel fluorescent protein that has been adapted from the corresponding full-length cDNA for higher solubility, brighter emission, and rapid chromophore maturation (8-12 hours). The filters used were FITC and PE. YFP HYQ - The YFP HYQ filter combination is designed for detection of emission from yellow fluorescent protein, which appears greenish within the relatively narrow passband, and is applicable with a range of other fluorochromes excited in the blue-green spectral region. mOrange has an extinction coefﬁcient equivalent to Its excitation maxima is at 506 nm and its emission maxima is at 517 nm. mOrange has an extinction coefﬁcient equivalent to For example, if your microscope has only two lasers, at 488nm and 561nm, you will not be able to use far red-FPs.

Unfortunately, also all one-photon spectra for the same dyes are shown in the list, so you may have to search a bit. mOrange, DsRed2 and TagRFP, however, there is a distinct blue shift of the 2PA band relative to the 1PA band. Cy5, Cy5.5). A region of high excitation is found in the UV spectrum. mOrange fluorescence images (green, middle column) were acquired using custom orange cube with 540/20 excitation and 575/30 emission filters.

Bestvater, et al., Two-photon fluorescence absorption and emission spectra of dyes relevant for cell imaging. Last, unlike CFP, TSapphire (like its parent GFP) exhibits monoexponential decay kinetics (shown in this study) and thus any lifetime reduction seen in TSapphire in the close presence of mOrange is more likely to . Undergoing a second oxidation step, each mFruit produces an acylimine linkage in the polypeptide backbone. Fig. 535/30 (520-550) Narrow Excitation Band Bandpass Barrier Filter. It is 1.5 to 3 times brighter than the most commonly used GFPs and YFPs. BsrBI is typically used at 37°C, but can be used at temperatures up to 50°C. It has an excitation/emission peak at 495/517 nm and can be coupled to distinct antibodies with the help of its reactive isothiocyanate group, which is binding to amino, sulfhydryl, imidazoyl, tyrosyl or carbonyl groups on proteins. Texas Red is spectrally similar to iFluor 594, TF4 (Tide Fluor 4), SunRed, Alexa Fluor . For time course measurements, dye 11-16 was reacted with 10 eq.

Red fluorescence emission from DsRed-Express can be observed within an hour after expression, 11 times faster than DsRed. Combining AOBS and spectral selection using the internal PMT, the system allows high versatility regarding both excitation and emission wavelength selection. Displaying red-shifted spectral profiles (excitation and emission maxima at 462 and 492 nanometers, respectively) when compared to other cyan members of this spectral class, mTFP1 has a total of 31 amino acid substitutions relative to the wild-type tetramer.

The emission and excitation maxima are distributed over the remarkably large ranges of about 550-650 and 540-590 nm, respectively; however, the variations in the spectra can be traced to a few key amino acids. Sticky ends from different BsgI sites may not be compatible. The extinction coefficient was 71000 M -1 cm -1. Unfortunately, the photostability of mOrange is only approximately 5 percent that of EGFP.
