Preparation and Storage
Background: Haptoglobin
Haptoglobin is an acute phase glycoprotein that is an inactive member of the peptidase S1 family of serine proteases. It is secreted by multiple cell types and binds with high affinity to circulating Hemoglobin. Association of Haptoglobin with free Hemoglobin protects tissues from Hemoglobin-mediated oxidative damage and facilitates Hemoglobin clearance. In addition, Haptoglobin has anti-inflammatory properties that are independent of Hemoglobin binding. It inhibits prostaglandin synthesis, scavenges nitric oxide, dampens the inflammatory response to endotoxins, and inhibits T cell proliferation and neutrophil respiratory bursts. Deletion of Haptoglobin in mice facilitates the development of autoimmune inflammation.
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 200 µL of Assay Diluent to each well.
- Add 20 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.
