Product Summary

The Quantikine Mouse Tie-2 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse Tie-2 in cell culture supernates, tissue homogenates, serum, and plasma. It contains NS0-expressed recombinant mouse Tie-2 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse Tie-2 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring mouse Tie-2.

Recovery

The recovery of mouse Tie-2 spiked to three levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Supernates (n=4) 106 98-119
EDTA Plasma (n=5) 107 95-120
Heparin Plasma (n=4) 102 87-113
Serum (n=4) 103 93-116

Linearity

To assess the linearity of the assay, samples containing or spiked with recombinant mouse Tie-2 in each matrix were diluted with Calibrator Diluent and then assayed.

Background: Tie-2

Tie-2, also known as Tek, is a transmembrane receptor tyrosine kinase (RTK) that functions as a receptor for Angiopoietin family proteins. It is expressed by embryonic and adult endothelial cells, hematopoietic stem cells, and a circulating population of proangiogenic monocytes. Tie-2 signaling is activated by Angiopoietins-1 and -4, while it can be either activated or inhibited by Angiopoietins-2 and -3. Tie-2 plays an important role in maintaining vascular integrity by mediating endothelial cell-smooth muscle cell communication and inhibiting endothelial cell apoptosis. It is also required for embryonic development of the endocardium. In addition, Tie-2 signaling mediates the quiescence of bone marrow stem cells in response to osteoblast-produced Angiopoietin-1. This quiescence is critical for maintaining an ongoing hematopoietic capability in the bone marrow.

Assay Procedure

Refer to the product for complete assay procedure.

Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
  1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
  2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

  3. 50 µL Assay Diluent
  4.   Add 50 µL of Assay Diluent to each well.

  5. 50 µL Standard, Control, or Sample
  6.   Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
  7.   Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

  8. 100 µL Conjugate
  9.   Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
  10.   Aspirate and wash 5 times.

  11. 100 µL Substrate Solution
  12.   Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

  13. 100 µL Stop Solution
  14.   Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
