ActoFactor™ Recombinant Mouse soluble TIE-1/Fc Chimera

  • Specification
  • Recommended Products
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. Murine TIE-1 cDNA encodes a 1134 amino acid (aa) precursor protein with a 22 aa putative signal peptide, a 733 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 murine soluble TIE-1 was fused with the Fc part of human IgG1. The recombinant mature sTIE-1/hFc is a disulfide-linked homodimeric protein. The sTIE-1/hFc monomers have a mass of approximately 105 kDa. As a result of glycosylation, the recombinant protein migrates as an approximately 130 kDa protein in SDS-PAGE under reducing conditions. The soluble receptor protein consists of the full extracellular domain (Val23-Glu749).
Product Overview
Mouse TEK expressed in CHO cells
Molecular Mass
260 kDa
CAT# CSC-CTK0790-20 (20 μg); CAT# CSC-CTK0790-100 (100 μg)
Expression System
CHO cells
Greater than 90% as determined by SDS-PAGE analysis.
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.
Lyophilized from a steril-filtered protein solution in PBS.
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water 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 rMu sTIE-1 should be used immediately or stored long-term in undiluted working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
