Product Details
Background
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.

Inter-assay Precision (Precision between assays) Three samples of known concentration were tested six times on one plate to assess intra-assay precision.
Spike Recovery
The spike recovery was evaluated by spiking 3 levels of human CD163 into health human serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 85% to 115% with an overall mean recovery of 100%.
The recovery ranged from 85% to 115% with an overall mean recovery of 100%.

Serum/Plasma – Thirty samples from apparently healthy volunteers were evaluated for the presence of CD163 in this assay. No medical histories were available for the donors.
