About Rac1
The protein encoded by this gene is a GTPase which belongs to the RAS superfamily of small GTP-binding proteins. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

About TRITC
TRITC (Tetramethylrhodamine isothiocyanate) is a historical fluorophore from the rhodamine family that has an excitation peak at 557 nm and an emission peak at 576. Commonly used in fluorescence microscopy, brighter alternatives with better stability characteristics are Alexa Fluor™ 546, Alexa Fluor™ 568, SETA-555, Janelia Fluor® 549, iFluor® 555, eFluor™ 570, DyLight™ 550, CF®540, CF®550R and CF®555.
