Flow Cytometry: L-Selectin/CD62L Antibody (DREG-56) - Chimeric [NBP2-81084] - Flow-cytometry using [NBP2-81084]. Human lymphocytes were stained with an isotype control (NBP2-52638, panel A) or the rabbit-chimeric version of DREG-56 (NBP2-81084, panel B) at a concentration of 1 ug/ml for 30 mins at RT. After washing, bound antibody was detected using a AF488 conjugated donkey anti-rabbit antibody and cells analysed on a FACSCanto flow-cytometer.

Application Notes
This chimeric rabbit antibody was made using the variable domain sequences of the original Mouse IgG1 format, for improved compatibility with existing reagents, assays and techniques. This antibody has been used in WB, IP and binding assays to define a lymphocyte homing receptor for PLN HEVs (Kishimoto, 1990). In vitro, this antibody has been shown to specifically inhibit over 90% of binding of human lymphocytes to HEVs within frozen sections of peripheral, but not mucosal, lymphoid tissue (Kishimoto, 1990). This antibody has also been used in labelling studies to demonstate that the trophectoderm of implantation-competent human embryos expresses L-selectin (Genbacev, 2003).

Background: L-Selectin/CD62L

L-selectin, also known as CD62L, is a type I transmembrane glycoprotein that is primarily expressed on leukocytes and has a role in cell adhesion and migration (1,2). L-selectin is closely related to the other family members E- and P-selectin (1,2). Human L-selectin protein is encoded by SELL and is 372 amino acids (aa) in length with a predicted molecular weight (MW) of ~30 kDa (1,2). However, due to glycosylation the observed MW ranges between 65-100 kDa and glycosylation is cell-type dependent (1,2). The L-selectin protein contains an N-terminal C-type lectin domain (CTLD), an epidermal growth factor (EGF)-like domain, two sequence consensus repeat (CSR) domains, a cleavage site, a transmembrane (TM) domain, and a short cytoplasmic tail (1,2).

L-selectin expressed on leukocytes binds to ligands expressed by endothelial cells where it plays a role in lymphocyte homing to secondary lymphoid organs (2-5). L-selectin specifically recognizes and binds to sulfated sialyl-Lewis epitopes of O-linked glycans (2-4). Ligands for L-selectin include glycosylation-dependent cell adhesion molecule-1 (GlyCAM-1), CD34, mucosal vascular addressin cell adhesion molecule-1 (MAdCAM-1), and P-selectin glycoprotein ligand-1 (PSGL-1) (2,4). Elevated levels of selectin ligands on tumor cells are associated with cancer progression and metastasis (3). High levels of L-selectin and soluble L-selectin (sL-selectin) has been implicated in a number of pathologies from viral infection and allergies, to sepsis and multiple sclerosis (2,4,5). For example, L-selectin has been shown to play a role in human immunodeficiency virus (HIV) infection. HIV envelope glycans, such as gp120, binds to L-selectin/CD62L on CD4+ T cells, facilitating viral adhesion (2,5). A disintegrin and metalloproteinase (ADAM)17 is the primary enzyme responsible for L-selectin shedding in leukocytes, which is triggered in response to inflammatory signals (1,2,5). AMAD17 inhibitors block L-selectin shedding and reduce viral release (2,5). Given their role in cancer and other diseases, selectins and their ligands are potential targets for therapeutic intervention (3,5). For instance, murine models have shown that anti-L-selectin antibodies can delay onset of graft versus host disease (5).
