Chemical Name: 4-Cyano-α-[[4-[(2-hydroxyethyl)methylamino]phenyl]methylene]benzeneacetonitrile
Biological ActivityHBC 530 is a mimic of green fluorescent protein (GFP) fluorophore for imaging RNA in live cells. Fluoresces when bound to Pepper aptamer; displays high affinity binding (Kd = 3.5 nM). Suitable for confocal and two-photon microscopy. Confocal excitation maximum = 488 nm, emission maximum= 495 - 595 nm. Two-photon excitation maximum = 976 nm, emission maximum= 475 - 575 nm.
To make a 1000x stock solution, add 200 μL DMSO (Cat. No. 3176).
