About GABA B Receptor 2
The multi-pass membrane protein encoded by this gene belongs to the G-protein coupled receptor 3 family and GABA-B receptor subfamily. The GABA-B receptors inhibit neuronal activity through G protein-coupled second-messenger systems, which regulate the release of neurotransmitters, and the activity of ion channels and adenylyl cyclase. This receptor subunit forms an active heterodimeric complex with GABA-B receptor subunit 1, neither of which is effective on its own. Allelic variants of this gene have been associated with nicotine dependence.[provided by RefSeq, Jan 2010]

About DyLight 633
DyLight™ 633 is a red-emitting fluroescent dye that can be excited by the 628 nm laser and collected using a 670/30 nm bandpass filter. DyLight™ 633 has an excitation peak of 638 nm and an emission peak of 658 nm, and is spectrally similar to Alexa Fluor™ 633. DyLight™ 633 is most commonly used in flow cytometery and fluorescence microscopy applications.
