Description Mouse CD44 is also known as Pgp-1, HCELL, HUTCH-I, HCAM, HERMES, and Ly-24. Clone IM7 reacts with murine CD44, an 80–95 kDa membrane glycoprotein. It is expressed by a variety of hematopoetic and non-hematopoetic cells. Different isoforms are generated by alternative splicing. Clone IM7 reacts with all isoforms and both allelic forms of CD44. CD44 functions as a receptor for hyaluronic acid (HA) and mediates cell-cell and cell-matrix interactions through its affinity for HA, and possibly also through its affinity for other ligands, such as osteopontin, collagens, and matrix metalloproteinases (MMPs). CD44 expression is upregulated on naive T cells upon activation and high CD44 expression is maintained on memory T cells. Therefore, CD44 is often used to discriminate CD44highantigen-experienced T cells from CD44low (CD62L+) naive T cells.
About CD44 and PE-Vio770
CD44 The protein encoded by this gene is a cell-surface glycoprotein involved in cell-cell interactions, cell adhesion and migration. It is a receptor for hyaluronic acid (HA) and can also interact with other ligands, such as osteopontin, collagens, and matrix metalloproteinases (MMPs). This protein participates in a wide variety of cellular functions including lymphocyte activation, recirculation and homing, hematopoiesis, and tumor metastasis. Transcripts for this gene undergo complex alternative splicing that results in many functionally distinct isoforms, however, the full length nature of some of these variants has not been determined. Alternative splicing is the basis for the structural and functional diversity of this protein, and may be related to tumor metastasis. [provided by RefSeq, Jul 2008]
PE-Vio770 PE-Vio® 770 from Miltenyi Biotec is a red-emitting tandem fluorophore that combines pycoerythrin (PE) and Vio®770. 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, Vio®770, which emitts light that can be captured with a 780/60 nm bandpass filter. PE-Vio®770 has an excitation peak at 565 nm and an emission peak at 775 nm and is a common alternative to PE-Cy7 and PE-H7.
