  • Description
  • TIE-1 and TIE-2/Tek comprise a receptor tyrosine kinase (RTK) subfamily with unique structural characteristics: two immunoglobulin-like domains flanking three epidermal growth factor (EGF)- like domains and followed by three fibronectin type III-like repeats in the extracellular region and a split tyrosine kinase domain in the cytoplasmic region. These receptors are expressed primarily on endothelial and hematopoietic progenitor cells and play critical roles in angiogenesis, vasculogenesis and hematopoiesis. Human TIE-1 cDNA encodes a 1124 amino acid (aa) precursor protein with an 18 aa putative signal peptide, a 727 aa extracellular domain and a 354 aa cytoplasmic domain. Whereas two ligands have been described for TIE-2 [angiopoietin-1 (Ang1) and angiopoietin-2 (Ang2)], so far no ligand was found for TIE-1. Recombinant human soluble TIE-1 was fused with the Fc part of human IgG1. The soluble receptor protein consists of the full extracellular domain (Met1-Glu749). The recombinant mature TIE-1/Fc is a disulfide- linked homodimeric protein. Human TIE-1/Fc monomer has a calculated molecular mass of approximately 105 kDa. As a result of glycosylation, the recombinant protein migrates as an approximately 125 kDa protein in SDS-PAGE under reducing conditions.

  • Product Overview
  • Human TEK expressed in Insect cells
  • Molecular Mass
  • 250 kDa
  • Size
  • CAT# CSC-CTK0595-20 (20 μg); CAT# CSC-CTK0595-100 (100 μg)
  • Expression System
  • Insect cells
  • Purity
  • Greater than 90% as determined by SDS-PAGE analysis.
  • Activity
  • Since a ligand for TIE-1 has not yet been identified, the recombinant protein was not tested for biological activity.
  • Endotoxin Level
  • Less than 1 EU/μg.
  • Formulation
  • Lyophilized from a steril-filtered protein solution in PBS.
  • Reconstitution
  • Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile PBS or medium to a concentration of 0,1 - 1,0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
  • Storage & Stability
  • The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rHu sTIE-1 should be used immediately or stored long-term in undiluted working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
