About CD68
This gene encodes a 110-kD transmembrane glycoprotein that is highly expressed by human monocytes and tissue macrophages. It is a member of the lysosomal/endosomal-associated membrane glycoprotein (LAMP) family. The protein primarily localizes to lysosomes and endosomes with a smaller fraction circulating to the cell surface. It is a type I integral membrane protein with a heavily glycosylated extracellular domain and binds to tissue- and organ-specific lectins or selectins. The protein is also a member of the scavenger receptor family. Scavenger receptors typically function to clear cellular debris, promote phagocytosis, and mediate the recruitment and activation of macrophages. Alternative splicing results in multiple transcripts encoding different isoforms. [provided by RefSeq, Jul 2008]

About PE-eFluor 610
PE-eFluor™ 610 (PE-eF610, RPE-eF610) from Thermo Fisher Scientific is an orange-emitting tandem fluorophore that combines pycoerythrin (PE) and eFluor™ 610. 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, eF610, which emitts light that can be captured with a 610/20 nm bandpass filter. PE-eF610 has an excitation peak at 565 nm and an emission peak at 607 nm, and is suitable alternative to PE-Texas Red®. PE-eF610 is mainly used for flow cytometry. This tandem is often a great option because of PE is excitable by multiple lasers due to its broad excitation spectrum and the eFluor™ 610 acceptor molecule emits brightly in the Orange/Red spectrum. Many cytometers are commonly set up with the 610/20 bandpass filter that can detect this fluorophore's emission. This dye is part of the larger eFluor™ dye family, developed by eBioscience which is now part of ThermoFisher Scientific.
