| Background | Vascular cell adhesion molecule 1 (VCAM-1), also known as CD16, is a cell surface sialoglycoprotein belonging to the immunoglobulin superfamily. Two forms of VCAM-1 with either six or seven extracellular Ig-like domains are generated by alternative splicing, with the longer form predominant. VCAM-1 is an endothelial ligand for very late antigen-4 (VLA-4) and alpha4β7 integrin expressed on leukocytes, and thus mediates leukocyte-endothelial cell adhesion and signal transduction. VCAM-1 expression is induced on endothelial cells during inflammatory bowel disease, atherosclerosis, allograft rejection, infection, and asthmatic responses. During these responses, VCAM-1 forms a scaffold for leukocyte migration. VCAM-1 also activates signals within endothelial cells resulting in the opening of an "endothelial cell gate" through which leukocytes migrate. VCAM-1 has been identified as a potential anti-inflammatory therapeutic target, the hypothesis being that reduced expression of VCAM-1 will slow the development of atherosclerosis. In addition, VCAM-1-activated signals in endothelial cells are regulated by cytokines indicating that it is important to consider both endothelial cell adhesion molecule expression and function during inflammatory processes.Immune CheckpointImmunotherapyCancer ImmunotherapyTargeted Therapy |
| Description | A DNA sequence encoding the extracellular domain (Met 1-Glu 698) of mouse VCAM1 (NP_035823.3) precursor was fused with the C-terminal His-tagged Fc region of human IgG1 at the C-terminus. |
| Source | HEK293 |
| Predicted N Terminal | Phe 25 |
| AA Sequence | Met 1-Glu 698 |
| Molecular Weight | The recombinant mouse VCAM1/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 922 a.a. and has a predicted molecular mass of 102 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rmVCAM1/Fc monomer is approximately 110-120 kDa due to glycosylation. |
| Purity | >90% as determined by SDS-PAGE |
| Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
| Bioactivity | Measured by the ability of the immobilized protein to support adhesion of U937 human histiocytic lymphoma cells. When cells are added to VCAM1-coated plates (10 ug/ml, 100 ug/well), approximately >70% cells will adhere specifically. |
| Formulation | Lyophilized from sterile PBS, pH 7.4. |
| Stability | The recombinant proteins are stable for up to 1 year from date of receipt at -70°C. |
| Usage | For Research Use Only |
| Storage | Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
