About Histone H2B
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene encodes a replication-dependent histone that is a member of the histone H2B family, and generates two transcripts through the use of the conserved stem-loop termination motif, and the polyA addition motif. The protein has antibacterial and antifungal antimicrobial activity. [provided by RefSeq, Aug 2015]

About DyLight 405
DyLight™ 405 has an excitation peak at 400 nm and an emission peak at 420 nm and is spectrally similar to Alexa Fluor™ 405 and Cascade Blue. DyLight™ 405 is most commonly used in flow cytometery and fluorescence microscopy applications.
