CD166 antigen is a 100-105kD typeI transmembrane glycoprotein that is a member of the immunoglobulin superfamily of proteins. In humans it is encoded by the ALCAM gene. The human gene was mapped to chromosome 3q13.1-q13.2 by fluorescence in situ hybridization of cDNA probes to metaphase chromosomes. It is also called CD166 (cluster of differentiation 166), MEMD, SC-1/DM- GRASP/BEN in the chicken, and KG-CAM in the rat. This gene is expressed on activated T cells, activated monocytes, epithelial cells, fibroblasts, neurons, melanoma cells, and also in sweat and sebaceous glands. CD166 plays an important role in mediating adhesion interactions between thymic epithelial cells and CD6+ cells during intrathymic T cell development. Recently, CD166 has also been used as a potential cancer stem cell marker.
Intended Use:Sandwich High Sensitivity BioAssay™ ELISA kit for Quantitative Detection of Rat ALCAM/Cd166.
Sensitivity:<10pg/ml
Range:78pg/ml-5000pg/ml
Specificity:Recognizes natural and recombinant Rat ALCAM/Cd166. There is no detectable cross-reactivity with other relevant proteins.
Test Principle:This Rat ALCAM/Cd166 BioAssay™ ELISA Kit was based on standard sandwich enzyme-linked immune- sorbent assay technology. A specific for ALCAM/Cd166 has been precoated onto 96-well plates. Standards(Expression system for standard: NSO; Immunogen sequence: W28-K527) and test samples are added to the wells, a biotinylated detection specific for ALCAM/Cd166 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Rat ALCAM/Cd166 amount of sample captured in plate.
Storage and Stability:Store powder at 4°C liquid at -20°C. Store other components at 4°C. Stable for at least 6 months For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
