About ICAM-4
This gene encodes the Landsteiner-Wiener (LW) blood group antigen(s) that belongs to the immunoglobulin (Ig) superfamily, and that shares similarity with the intercellular adhesion molecule (ICAM) protein family. This ICAM protein contains 2 Ig-like C2-type domains and binds to the leukocyte adhesion LFA-1 protein. The molecular basis of the LW(A)/LW(B) blood group antigens is a single aa variation at position 100; Gln-100=LW(A) and Arg-100=LW(B). Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

About Brilliant Violet 480
Brilliant™ Violet 480 (BV480) is a green-emitting non-tandem polymer fluorophore that can be excited by the 405 nm Violet laser and collected using a 525/40 bandpass filter. BV480 has an excitation peak at 436 nm and an emission peak at 478 nm, and provides an optimized alternative to BV510. Other dyes that are similar include StarBright Violet 475 (Bio-Rad) While BV480 can be detected on the same filter as BV510, its emmision profile reduces spillover into the BV605, BV650, and BV711 channels. Additionally BV480's excitation profile will reduce cross-laser excitation with the UV laser, resulting in less spillover into UV channels than BV510. These advantages make BV480 an optimal choice for flow cytometry panels using multiple reagents on Violet and/or UV lasers. 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.
