About Dnmt3b
CpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a DNA methyltransferase which is thought to function in de novo methylation, rather than maintenance methylation. The protein localizes primarily to the nucleus and its expression is developmentally regulated. Mutations in this gene cause the immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome. Eight alternatively spliced transcript variants have been described. The full length sequences of variants 4 and 5 have not been determined. [provided by RefSeq, May 2011]

About DyLight 550
DyLight™ 550 has an excitation peak at 562 nm and an emission peak at 576 nm and is spectrally similar to Alexa Fluor™ 546, Alexa Fluor™ 555, Cy3 and TRITC. DyLight™ 550 is most commonly used in flow cytometery and fluorescence microscopy applications.
