Background: alpha 1-Acid Glycoprotein
Alpha-1-acid Glycoprotein is an acute-phase serum protein that is produced by the liver in response to inflammation and infection. It is a 183 amino acid protein with five N-linked glycans that comprise 45% of its 43 kDa mass. Alterations of N-glycosylation is associated with certain pathophysiological states. alpha-1-acid glycoprotein belongs to the lipocalin family and binds numerous basic and neutral lipophilic drugs and steroid hormones.
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.
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.
