About EphB2
This gene encodes a member of the Eph receptor family of receptor tyrosine kinase transmembrane glycoproteins. These receptors are composed of an N-terminal glycosylated ligand-binding domain, a transmembrane region and an intracellular kinase domain. They bind ligands called ephrins and are involved in diverse cellular processes including motility, division, and differentiation. A distinguishing characteristic of Eph-ephrin signaling is that both receptors and ligands are competent to transduce a signaling cascade, resulting in bidirectional signaling. This protein belongs to a subgroup of the Eph receptors called EphB. Proteins of this subgroup are distinguished from other members of the family by sequence homology and preferential binding affinity for membrane-bound ephrin-B ligands. Allelic variants are associated with prostate and brain cancer susceptibility. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2015]

About Alexa Fluor 700
Alexa Fluor™ 700 (AF700, Alexa 700) has an excitation peak at 702 nm and an emission peak at 723 nm, and is spectrally similar to iFluor® 680 (ATT Bioquest) and iFluor® 700 (ATT Bioquest). Alexa 700 is commonly used in Flow Cytometry and is similar in size, brightness and application to iFluor® 700 and Vio® R720.
