CD62L / FITC / REAL163

Product Details

Description	Clone REAL163 is an antibody fragment derived from the full CD62L antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAlease Complex to bind markers with high avidity. \| Clone REAL163 recognizes the human CD62L antigen, a 74 kDa single-pass type I membrane protein which is also known as L-selectin, LECAM-1, or LAM-1. CD62L is a member of the selectin family of cell surface molecules and binds a series of glycoproteins including CD34, GlyCAM-1, and MAdCAM-1. Most hematopoietic cells express CD62L, including peripheral blood B cells, T cells, monocytes, granulocytes, thymocytes, and some myeloid cells from bone marrow. Expression on resting naive, central memory, and some effector memory T cells regulates their migration via endothelial venules to peripheral lymph nodes and Peyer’s patches. The CD62L antigen also contributes to the recruitment of leukocytes from the blood to areas of inflammation. Disruption of CD62L expression has detrimental effects on T cell migration and immune responses. Antigenic activation in the lymph node leads first to rapid CD62L shedding by protease cleavage and then to transcriptional suppression. \| Always use fresh material for immunofluorescent staining of CD62L+ cells. For optimal results, the cells should not be older than 8–12 hours. Keep cells continuously cold. CD62L-expression may be rapidly lost due to shedding. \| The REAlease Kits consist of the respective fluorochrome-conjugated REAlease Complexes and the REAlease Support Kit for removal of the REAlease Complexes and optional relabeling with different fluorochrome-conjugated REAlease Complexes.

About CD62L
This gene encodes a cell surface adhesion molecule that belongs to a family of adhesion/homing receptors. The encoded protein contains a C-type lectin-like domain, a calcium-binding epidermal growth factor-like domain, and two short complement-like repeats. The gene product is required for binding and subsequent rolling of leucocytes on endothelial cells, facilitating their migration into secondary lymphoid organs and inflammation sites. Single-nucleotide polymorphisms in this gene have been associated with various diseases including immunoglobulin A nephropathy. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Oct 2009]

About 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.
