About ErbB4
This gene is a member of the Tyr protein kinase family and the epidermal growth factor receptor subfamily. It encodes a single-pass type I membrane protein with multiple cysteine rich domains, a transmembrane domain, a tyrosine kinase domain, a phosphotidylinositol-3 kinase binding site and a PDZ domain binding motif. The protein binds to and is activated by neuregulins and other factors and induces a variety of cellular responses including mitogenesis and differentiation. Multiple proteolytic events allow for the release of a cytoplasmic fragment and an extracellular fragment. Mutations in this gene have been associated with cancer. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]

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.
