Human Angiopoietin-2 Quantikine ELISA Kit Summary
Sample Values
Serum/Plasma - Samples from apparently healthy volunteers were evaluated for the presence of human Angiopoietin-2 in this assay. No medical histories were available for the donors used in this study.Sample Type | Mean (pg/mL) | Range (pg/mL) | Standard Deviation (pg/mL) |
Serum (n=60) | 2494 | 1065-8907 | 1341 |
EDTA plasma (n=35) | 1964 | 1071-4389 | 808 |
Heparin plasma (n=35) | 2049 | 1009-4973 | 913 |
Saliva - Nine samples were evaluated for the presence of human Angiopoietin-2 in this assay and ranged from 247-822 pg/mL.
Sample | Values (pg/mL) |
HUVEC Culture 1 | 2326 |
HUVEC Culture 2 | 7611 |
Note: Significant levels of Angiopoietin-2 are found in fetal bovine, bovine, porcine, equine, and rabbit serum. The background level of Angiopoietin-2 in control medium should be determined and subtracted from samples of conditioned medium.

Preparation and Storage
Background: Angiopoietin-2
Angiopoietins, Ang-1, Ang-2, and Ang-3 (mouse)/Ang-4 (human), are natural agonists or antagonists of the Tie-2 receptor tyrosine kinase and are important modulators of angiogenesis. Two domains characterize the angiopoietin family of proteins: an N-terminal coiled-coil domain that mediates homo-oligomerization, and a C-terminal fibrinogen-like domain that binds Tie-2.
Assay Procedure
Refer to the product- Prepare all reagents, standard dilutions, and samples as directed in the product insert.
- Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
- Add 100 µL of Assay Diluent to each well.
- 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.
- Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
- Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
- Aspirate and wash 4 times.
- Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.
- Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.

Urine was very low concentration & mostly undetectable at 2-fold. Plasma & Serum showed pretty good linearity up to 20-fold dilution. Almost no matrix effect in plasma at 20-fold dilution.
another excellent ELISA from R and D
