Product Summary

The Quantikine Human CD163 immunoassay is a 4.5 hour solid phase ELISA designed to measure human soluble CD163 in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant human CD163 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human CD163 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 human CD163.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

Background: CD163

CD163, also known as M130 and p155, is a transmembrane scavenger receptor that is expressed on monocytes and macrophages and is inducible by immunosuppressant glucocorticoids and IL-10. A soluble form is shed from the cell surface by TACE or neutrophil elastase mediated cleavage in response to oxidative stress, Prostaglandin F2a stimulation, or the activation of Fc gamma receptors, TLR1, 2, 5, or 6. CD163 mediates monocyte binding to bacteria, leading to the release of inflammatory cytokines. It is essential for the circulatory clearance of hemoglobin-haptoglobin (Hb-Hp) complexes as well as free hemoglobin. It can also mediate monocyte-erythroblast adhesion and promote erythroblast expansion. CD163 binds and internalizes the cytokine TWEAK, and the ratio of soluble CD163 to TWEAK in the plasma is elevated during atherosclerosis.

  4.   Add 100 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.
  7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

  8. 200 µL Conjugate
  9.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
  10.   Aspirate and wash 4 times.

  11. 200 µL Substrate Solution
  12.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.

  13. 50 µL Stop Solution
  14.   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.

Human CD163 Quantikine ELISA Kit
By Anonymous on 12/15/2016
Sample Tested: EDTA Plasma

Plasma was isolated from blood drawn in EDTA tubes from HIV+/ART and HIV- healthy controls. sCD163 was measured using the Quantikine elisa kit for human sCD163 (cat# DC1630) following the protocol supplied in the kit. Plasma samples were diluted 1:10 before use in the assay.

Figure legends:
a) Standard curve for sCD163 from which concentrations in plasma were extrapolated
b) Quantitated data from HIV+/ART and HIV- group.

Concentrations are expressed in ng/ml.
