Description

Description: The eBio156-4H9 monoclonal antibody reacts with the human CD48 antigen, also known as B cell activation marker 1, SLAM family member 2, Blast-1 (human), and OX-45 (rat). CD48, a member of the SLAM family and Ig superfamily, is a 45 kDa GPI-linked glycoprotein expressed on the majority of hematopoietic cells. CD2 is the low affinity ligand for CD48.Recent publications have reported differential expression in mice of members of the SLAM family including CD48, CD150, and CD244 among functionally distinct bone marrow hematopoietic progenitors providing a useful tool for prediction of the primitiveness of hematopoietic progenitors. Expression of CD48 in hematopoietic cells is found on many leukocytes with little to none on granulocytes and absent on platelets and erythrocytes. Expression increases on B cells with activation. Applications Reported: This eBio156-4H9 (156-4H9) antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBio156-4H9 (156-4H9) antibody has been tested by flow cytometric analysis of human peripheral blood cells. This can be used at less than or equal to 1 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

CD48, also known as Blast-1, is a 45 kDa glycoprotein that is part of the SLAM and Ig superfamilies. It is a GPI-anchored protein broadly expressed on most hematopoietic cells, including lymphocytes and monocytes, but is weakly expressed on granulocytes and absent on platelets, fibroblasts, epithelium, and endothelium. CD48 plays a critical role in adhesion and T cell activation, serving as a high-affinity ligand for 2B4 and a low-affinity ligand for CD2. The interaction between 2B4 and CD48 among NK and NK-T cells regulates cell proliferation. CD48 is involved in eosinophil activation and its expression increases in several infectious diseases. It is also a marker for detecting defects in the GPI anchoring structure in patients with paroxysmal nocturnal hemoglobulinuria (PNH). Recent studies have highlighted the differential expression of SLAM family members, including CD48, CD150, and CD244, among bone marrow hematopoietic progenitors. This provides a useful tool for predicting the primitiveness of hematopoietic progenitors: hematopoietic stem cells (HSCs) are CD150(+)CD244(-)CD48(-), non-self-renewing multipotent progenitors (MPPs) are CD244(+)CD150(-)CD48(-), and the most restricted progenitors are CD48(+)CD244(+)CD150(-). Additionally, the 2B4-CD48 interaction may be involved in the pathology of allergic airway diseases, offering a potential pharmacological target for treating conditions like allergic rhinitis and asthma.
