Description

Armenian Hamster Monoclonal Antibody

Description: The R1-2 monoclonal antibody reacts with mouse CD49d, the 150 kDa integrin alpha4 subunit. The complex of CD49d non-covalently associated with integrin beta1 (CD29), also known as VLA-4, is a receptor for fibronectin and VCAM-1 (CD106). This complex is expressed by thymocytes, peripheral lymphocytes, monocytes and eosinophils. CD49d also associates with integrin b7 and binds to the Mucosal vascular Addressin (MAdCAM-1). Applications Reported: The R1-2 antibody has been reported for use in flow cytometric analysis. Applications Tested: The R1-2 antibody has been tested by flow cytometric analysis of mouse splenocytes. 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. Super Bright 702 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 702 nm. We recommend using a 710/50 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome. When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Staining Buffer (Product No. SB-4400) to minimize any non-specific polymer interactions.

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.
