About B7-H4
This gene encodes a protein belonging to the B7 costimulatory protein family. Proteins in this family are present on the surface of antigen-presenting cells and interact with ligand bound to receptors on the surface of T cells. Studies have shown that high levels of the encoded protein has been correlated with tumor progression. A pseudogene of this gene is located on chromosome 20. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

About Brilliant Violet 510
Brilliant™ Violet 510 (BV510) is a green-emitting non-tandem polymer fluorophore that can be excited by the 405 nm Violet laser and collected using a 510/50 bandpass filter. BV510 has an excitation peak at 405 nm and an emission peak at 510 nm, and is similar to StarBright Violet 515 (Bio-Rad). BV510 is most often used in flow cytometry due to its improved signal-to-noise over alternatives like V500 and AmCyan. This dye is part of the Brilliant™ Violet dye line. BV510 and BV480 are the only dyes in the Brilliant™ Violet dye family that are not tandem fluorophores based off the BV421 polymer core, but they have nearly the same maximum excitation.
