  • Molecular Characterization
    Online(Gln 28 - Glu 480) AAH15969

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 75.7 kDa. The protein migrates as 90-120 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >98% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

  • Background
    Inter-Cellular Adhesion Molecule 1 (ICAM-1) is also known as Cluster of Differentiation 54 (CD54), is a member of the immunoglobulin superfamily, and is a cell surface glycoprotein which is typically expressed in low concentrations on endothelial cells and cells of the immune system. The protein encoded by this gene is a type of intercellular adhesion molecule continuously present in low concentrations in the membranes of leukocytes and endothelial cells. Upon cytokine stimulation, the concentrations greatly increase. ICAM-1 can be induced by interleukin-1 (IL-1) and tumor necrosis factor alpha (TNFα) and is expressed by the vascular endothelium, macrophages, and lymphocytes. ICAM-1 is a ligand for LFA-1 (integrin), a receptor found on leukocytes. When activated, leukocytes bind to endothelial cells via ICAM-1/LFA-1 and then transmigrate into tissues. ICAM-1 has been implicated in subarachnoid hemorrhage (SAH). Levels of ICAM-1 are shown to be significantly elevated in patients with SAH over control subjects in many studies. ICAM-1 expressed by respiratory epithelial cells is also the binding site for rhinovirus, the causative agent of most common colds.

ACROBiosystems治疗性抗体的功效不仅取决于Fab片段及其与靶抗原的结合活性,还取决于Fc片段及其与关键Fc受体的相互作用。Fc片段对FcRn的结合亲和力(FCGRT&B2M)将预测抗体的半衰期,而Fc片段与FcγRIIIa(CD16a)之间的结合亲和力将影响抗体引发ADCC的能力(抗体依赖性细胞介导的细胞毒性)。因此,必须在抗体工程化过程中针对一组受体测试候选人。ACROBiosystems提供了完整的重组Fc受体蛋白集合,包括它们的常见变体,以帮助您加快mAb的开发。
