Rat Tie2 / TEK Protein (Fc Tag)

Tie-2, Tie2

100ug (NPP1700) Please inquiry

Catalog Number	P80063-R02H
Organism Species	Rat
Host	Human Cells
Synonyms	Tie-2, Tie2
Molecular Weight	The recombinant rat TEK/Fc is a disulfide-linked homodimer. The reduced monomer comprises 962 amino acids and predicts a molecular mass of 108 kDa. The apparent molecular mass of the rat TEK/Fc monomer is approximately 120-130 kDa in SDS-PAGE under reducing conditions due to glycosylation.
predicted N	Ala 23
SDS-PAGE
Purity	> 95 % as determined by SDS-PAGE
Protein Construction	A DNA sequence encoding the rat TEK (NP_001099207.1) extracellular domain (Met 4-Leu 743) was fused with the Fc region of human IgG1 at the C-terminus.
Bio-activity	1. Measured by its binding ability in a functional ELISA. 2. Immobilized S1h-3C-mANGPT2 (P50298-M07H) at 10 μg/mL (100 μL/well) can bind ratTEK-Fc. The EC₅₀ of ratTEK-Fc is 0.26-0.62μg/mL.
Research Area	Immunology \|Inflammation / Inflammatory Mediator \|Inflammatory Cytokines & Chemoki and Receptors \|Angiopoietins and Angiopoietin-like Protein Families
Formulation	Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Background	TEK, or TIE-2, is an endothelial cell-specific receptor tyrosine kinase (RTK) that is known as a functioning molecule of vascular endothelial cells. TEK comprises a subfamily of RTK with TIE, and these two receptors play critical roles in vascular maturation, maintenance of integrity and remodeling. Targeted mutagenesis of both Tek and its agonistic ligand, Angiopoietin-1, result in embryonic lethality, demonstrating that the signal transduction pathways mediated by this receptor are crucial for normal embryonic development. TEK signaling is indispensable for the development of the embryonic vasculature and suggests that TEK signaling may also be required for the development of the tumor vasculature.
