About CD3 epsilon
The protein encoded by this gene is the CD3-epsilon polypeptide, which together with CD3-gamma, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T-cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. The epsilon polypeptide plays an essential role in T-cell development. Defects in this gene cause immunodeficiency. This gene has also been linked to a susceptibility to type I diabetes in women. [provided by RefSeq, Jul 2008]

About PerCP-Vio700
PerCP-Vio® 770 is a far-red-emitting tandem fluorophore that combines PerCP and a Vio®770 dye. The donor, PerCP, can be excited by the 488 nm blue laser and transfers energy to the acceptor, Vio®770, which emits light that can be captured with a 780/60 nm bandpass filter. APC-Vio®770 has an excitation peak at 482 nm and an emission peak at 704 nm, and is spectrally similar to PerCP-Cy5.5 and PerCP-eF710. PerCP-Vio®770 is known to be very bright and photostable, as well as being stable when treated with fixatives. These favorable characteristics that make it useful in multiple different applications such as flow cytometry and Fluorescence Microscopy. The large stokes shift can be advantageous when trying to fit more colors into a multicolor panel. The Vio® dye family are products of Miltenyi Biotec, with many antibody conjugates designed and validated for flow cytometry.
