Just like many other xanthene fluorophores, TAMRA is a available as two isomers (5- and 6-isomer) which have nearly identical optical properties. Figure 5.3. The presence of several minor bands in lanes 2, 3, and 4 was probably due to incomplete ligation (Figure 5). FAM Emission. Similar to Cy3, TAMRA is very stable and bright; therefore, it is an excellent fluorochrome. It must be strongly emphasized that IAPP–membrane binding is a complex thermodynamic process, with separate parameters governing membrane partition, nucleation, and growth of membrane-bound oligomers. As shown in Figure 5, the two major bands on the gel electropherogram corresponded to the TMR-BPDE-ss90mer products and unligated 37mer (oligo 1), respectively (lanes 3 and 4). Despite all the above, TRITC has proven to be a very useful fluorochrome. The following protocol for labeling proteins with tetramethylrhodamine-5-(and-6)-iodoacetamide represents a general guideline.

To conduct the studies described above, the corresponding experiments are suggested as the following protocols. The fluorescent probe has been used extensively to label numerous proteins and other biomolecules, including actin (Glacy, 1983; Wang, 1985; Meige and Wang, 1986), myosin light chains (Mittal et al., 1987), α-actin (Simon and Taylor, 1988; Stickel and Wang, 1988), blood coagulation factor Va (Isaacs et al., 1986), and histones (Murphy et al., 1982). Error bars indicate standard deviation in at least three experiments. (B) Interior of the G-ang base. Tetramethylrhodamine (TMR) attached to Cys-374 of actin emits polarized fluorescence at ≈45° with respect to the filament axis. In contrast, traditional radioactive DNA damage probes only provide the information on radioactive intensity. Tetramethylrhodamine-5-(and-6)-iodoacetamide is soluble in DMF and DMSO. C 25 H 22 N 2 O 5. The resulting binding isotherm has an apparent KD of ~ 50 nM, corresponding to a membrane partition coefficient of 2 × 105. Tetramethylrhodamine B isothiocyanate isomer R (40 mg; Sigma) and 100 mg of either amino-dextran (to make the fixable tracer RDA) or carboxy-dextran (to make the nonfixable tracer RDX) are dissolved in 3 ml of dimethyl sulfoxide at 97°C in a waterbath. Proteins are then blotted on PVDF membranes and visualized with anti-His antibodies. This iodoacetamide derivative of tetramethylrhodamine can be used to label sulfhydryl groups to form a thioether bond formation. The absorbance and emission maxima of TAMRA conjugates are 553 nm and 575 nm respectively. The nonspecific adsorption of TRITC to proteins via hydrophobic interactions and subsequent slow release or exchange may cause significant background fluorescence; the use of DMSO as a solvent appears to diminish this problem (Goding, 1976). B. Cordier, M.K. Figure 5.2. Care must be taken to protect these reagents from light, not only to maintain the fluorescent yield of the rhodamine derivative, but also to protect the iodoacetyl group from light-catalyzed breakdown. Concentrated stock solutions may be prepared in these solvents prior to addition of a small aliquot to an aqueous reaction mixture. The presence of the gapped TMR-ds90mer supported this explanation. TAMRA NHS is an amine reactive reagent. The slit is adjustable, allowing the image size to be limited so that the two separate images can be aligned on the image sensor of the camera. To measure the Nanodisc diffusion time, 10 autocorrelation traces of 10 nM NR in the presence of 10 μM Nanodiscs are collected, averaged, and fit with the single-component FCS equation to determine τb. Slowly add 25 to 50 μl of the tetramethylrhodamine-5-(and-6)-iodoacetamide solution to each milliliter of the protein solution while mixing. The spectral properties of these derivatives are similar to native rhodamine. Due to the excitation of the BV421 donor by the 355 nm (UV) laser line, there may be spillover into the BUV737 detector off of the UV laser. Once the oligonucleotide is disrupted by, for example, an exonucleolytic reaction, excitation at 494 nm will result in emission at 518 nm.
