About VSIG4
This gene encodes a v-set and immunoglobulin-domain containing protein that is structurally related to the B7 family of immune regulatory proteins. The encoded protein may be a negative regulator of T-cell responses. This protein is also a receptor for the complement component 3 fragments C3b and iC3b. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

About PE-Cy7
PE-Cyanine®7 (PE-Cy7, RPE-Cy7) is a far red-emitting tandem fluorophore that combines phycoerythrin (PE) and Cy7. The donor molecule, PE can be excited by the 488-nm blue, 532-nm green, or 561-nm yellow-green laser and and transfers energy to the acceptor molecule, Cy7, which emitts light that can be captured with a 780/60 nm bandpass filter. PE-CY7 has an excitation peak at 565 nm and an emission peak at 778 nm, and is a suitable alternative to PE-Vio®770 and PE-Fire™ 780.
