About HOXA9
In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic development. This gene is part of the A cluster on chromosome 7 and encodes a DNA-binding transcription factor which may regulate gene expression, morphogenesis, and differentiation. This gene is highly similar to the abdominal-B (Abd-B) gene of Drosophila. A specific translocation event which causes a fusion between this gene and the NUP98 gene has been associated with myeloid leukemogenesis. Read-through transcription exists between this gene and the upstream homeobox A10 (HOXA10) gene.[provided by RefSeq, Mar 2011]

About DyLight 488
DyLight™ 488 has an excitation peak at 493 nm and an emission peak at 518 nm and is spectrally similar to Alexa Fluor™ 488, fluorescein and FITC. DyLight™ 488 is most commonly used in flow cytometery, and fluorescence microscopy applications.
