Description Clone REA207 recognizes the CD85a antigen, a immunoglobulin superfamily transmembrane glycoprotein also known as leukocyte immunoglobulin-like receptor member 3 (LIR-3) or immunoglobulin-like transcript 5 (ILT5). CD85a is preferentially expressed by monocytes, macrophages, dendritic cells, and granulocytes. It provides inhibitory signals through interaction with MHC class I molecules and becomes activated upon co-ligation of CD85a and immune receptors, such as CD32 and the B cell receptor. CD85a down-regulates antigen-induced B cell–activation by recruiting phosphatases to its immunoreceptor tyrosine-based inhibitory motifs. | Additional information: Clone REA207 displays negligible binding to Fc receptors. |
About CD85a and FITC
CD85a This gene is a member of the leukocyte immunoglobulin-like receptor (LIR) family, which is found in a gene cluster at chromosomal region 19q13.4. The encoded protein belongs to the subfamily B class of LIR receptors which contain two or four extracellular immunoglobulin domains, a transmembrane domain, and two to four cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs). The receptor is expressed on immune cells where it binds to MHC class I molecules on antigen-presenting cells and transduces a negative signal that inhibits stimulation of an immune response. It is thought to control inflammatory responses and cytotoxicity to help focus the immune response and limit autoreactivity. Multiple transcript variants encoding different 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.
