Background: CEACAM-1/CD66aCEACAM-1, also known as CD66a, is an immunoglobulin superfamily protein that is expressed on neutrophils, activated NK cells, bile duct and colonic epithelial cells, and endothelial cells. CEACAM-1 is heavily glycosylated and carries high mannose residues and (sialyl) Lewis-x. It is expressed as at least three soluble and seven transmembrane isoforms, with variations occurring in both the ECD and cytoplasmic region. It engages in homotypic adhesion and heterotypic adhesion with CEACAM-3/CD66d and CEACAM-6/CD66c. On neutrophils, CEACAM-1 additionally binds to dendritic cell DC-SIGN via its Lewis-x moiety, inducing dendritic cell maturation and a subsequent Th1-type response.

Assay Procedure Refer to the product datasheet for the 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. 1、Prepare all reagents, standard dilutions, and samples as directed in the product insert. 2、Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal. 3、Add 50 μL of Assay Diluent to each well. 4、Add 50 μL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours. 5、Aspirate each well and wash, repeating the process 4 times for a total of 5 washes. 6、Add 100 μL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours. 7、Aspirate and wash 5 times. 8、Add 100 μL Substrate Solution to each well. 9、Add 100 μL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm. |
