Description Clone REA221 recognizes CD82, a member of the four transmembrane domain, tetraspanin family. Tetraspanins contain short, cytoplasmic amino and carboxyl termini and two extracellular loops of unequal sizes and can be distinguished from other membrane proteins, with same topology, due to conserved residues within the transmembrane domains and in the larger extracellular loops. CD82 interacts with other tretaspanins and membrane proteins, thus regulating several functions such as signal transduction. On the surface of tumor cells, CD82 interacts with integrins and is suggested to serve as a supressor of tumor metastasis. In addition, on immune cells such as T cells, CD82 associates with CD81, CD4, or CD8 and class II major histocompatibility complex (MHC), components of the antigen-processing and presentation pathway and tetraspanin CD63, in dendritic cells. Expression of CD82 is found on dendritic cells, monocytes, granulocytes, lymphocytes, epithelial, and endothelial cells. | Additional information: Clone REA221 displays negligible binding to Fc receptors. |
About CD82 and FITC
CD82 This metastasis suppressor gene product is a membrane glycoprotein that is a member of the transmembrane 4 superfamily. Expression of this gene has been shown to be downregulated in tumor progression of human cancers and can be activated by p53 through a consensus binding sequence in the promoter. Its expression and that of p53 are strongly correlated, and the loss of expression of these two proteins is associated with poor survival for prostate cancer patients. Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
FITC Fluorescein isothiocyanate (FITC) has an excitation peak at 495 nm and an emission peak at 519 nm. The name FITC is a misnomer in that the isothiocyanate is a reactive form of this dye. Once FITC is conjugated to an antibody, it is simply Fluorescein conjugated. FITC is one of the most widely used dyes for fluorescent applications, therefore most instruments come standard with a 488 nm laser and FITC filter set up. FITC is commonly conjugated to secondary antibodies and used in applications such as flow cytometry, immunocytochemistry, and immunohistochemistry. FITC is relatively dim, sensitive to photobleaching and it is susceptible to changes is pH. There are better performing alternatives to FITC, like Vio®Bright 515, Alexa Fluor™ 488, iFluor® 488, CF®488A and DY-488. FITC is a long-time generic dye with no sole manufacturer or trademark.
