Instrumentations. Rhodamine 640 has a better performance compared with Rhodamine 6G which is attributed to the greater spectral overlap of the Rhodamine 6G fluorescence spectrum with the plasmon resonance of gold, leading to an increased energy transfer and fluorescence quenching for Rhodamine 6G by gold. 1. Rhodamine B is often mixed with herbicides to show where they have been used. Use in Multiple Applications Rhodamine phalloidin can be used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations. Rhodamine 6G (R6G), gold (III) chloride trihydrate, sodium citrate tribasic dihydrate and paraformaldehyde were purchased from Sigma (www.sigmaaldrich.com) and were of analytical grade.An aqueous stock solution of rhodamine 6G at the concentration of 10 −3 M was prepared by diluting an appropriate amount of the solid in the 4-fold distilled water.
