Description
The 1A29 monoclonal antibody specifically recognizes ICAM-1 which is also known as CD54. ICAM-1 is an 85 kDa type I transmembrane glycoprotein that is encoded by Icam1 (Intercellular adhesion molecule 1). It is expressed on vascular endothelium in lymphoid tissues, thymic stromal cells, peripheral blood monocytes, peritoneal macrophages and mast cells, dendritic cells, and weakly on peripheral lymphocytes and thymocytes. ICAM-1 is a ligand for LFA-1 (CD11a/CD18) and Mac-1 (CD11b/CD18). Its expression is upregulated on activated lymphocytes and endothelial cells. 1A29 mAb inhibits Phorbol 12-Myristate 13-Acetate (PMA)-induced aggregation of phytohemagglutinin (PHA)-stimulated splenic blasts, as well as the adhesion of mitogen-stimulated blasts to high endothelial venule (HEV) cells and purified ICAM-1. The 1A29 antibody can reportedly inhibit leucocyte infiltration in in vivo systems, blocks induction of experimental allergic encephalomyelitis, and reduces NK-cell adhesion to tumor cells.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.
1. Researchers should determine the optimal concentration of this reagent for their individual applications.
2. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
3. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
4. An isotype control should be used at the same concentration as the antibody of interest.
5. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
