About ACTR1B
This gene encodes a 42.3 kD subunit of dynactin, a macromolecular complex consisting of 10 subunits ranging in size from 22 to 150 kD. Dynactin binds to both microtubules and cytoplasmic dynein and is involved in a diverse array of cellular functions, including ER-to-Golgi transport, the centripetal movement of lysosomes and endosomes, spindle formation, chromosome movement, nuclear positioning, and axonogenesis. This subunit, like ACTR1A, is an actin-related protein. These two proteins, which are of equal length and share 90% amino acid identity, are present in a constant ratio of approximately 1:15 in the dynactin complex. [provided by RefSeq, Aug 2008]

About DyLight 350
DyLight™ 350 has an excitation peak of 353 nm and an emission peak of 432 nm. It is spectrally similar to Alexa Fluor™ 350, iFluor® 350, AMCA, and Thioflavin T. DyLight™ 350 is most commonly used in flow cytometery and fluorescence microscopy applications.
