Anti-Mouse Tie-2

NS0-Derived Recombinant Mouse Tie-2 Extracellular Domain

This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.

Lyophilized

The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Neutralization: This antibody is useful for neutralization of Mouse Tie-2 bioactivity. The antibody dose required to neutralize 50% (ND₅₀) of the biological activity of Mouse Tie-2 (at 50 ng/ml) is 2 - 8 µg/ml.
Blocking: In a functional ELISA, 2-8 µg/mL of this antibody will block 50% of the binding of 50 ng/mL of biotinylated Recombinant Human Angiopoietin-2 to immobilized Recombinant Mouse Tie-2 Fc Chimera coated at 4 µg/mL (100 µL/well). At 100 μg/mL, this antibody will block >90% of the binding.

Goat Anti-Mouse Tyrosine Kinase With Immunoglobulin And Epidermal Growth Factor Homology Domain 2 (Tie-2) recognizes Mouse Tie-2. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

Tyrosine kinase with immunoglobulin-like and EGF-like domains 2 (Tie-2) are novel endothelial cell tyrosine kinase receptors that are essential for vascular development and remodeling in the embryo.¹ They are expressed almost exclusively in endothelial cells.² Tie-2 is functional in pericytes and may play an important role in the progression of diabetic retinopathy, by regulating pericyte loss and influencing the activation state and recruitment of pericytes.³ Tie2 has been shown to be up-regulated in psoriasis and in breast cancer tissue and blocking Tie2 action inhibits tumor angiogenesis and tumor growth.
