Predicted Species ReactivityHuman
ELISA Kit Detection MethodColorimetric, OD450 nm
ELISA Kit Duration~ 3 Hours
ELISA Kit PrincipleAviva's human CES1 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for CES1 has been precoated onto 96-well plates. Standards(Expression system for standard: NS0, Immunogen sequence: G18-L567) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for CES1 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 absorbance of yellow is proportional to the human Fibronectin amount of sample captured in plate.

Protein NameLiver carboxylesterase 1
Description of TargetLiver carboxylesterase 1 also known as carboxylesterase 1 (CES1, hCE-1 or CES1A1) is an enzyme that in humans is encoded by the CES1 gene. This gene is mapped to 16q12.2. It encodes a member of the carboxylesterase large family. The family members are responsible for the hydrolysis or transesterification of various xenobiotics, such as cocaine and heroin, and endogenous substrates with ester, thioester, or amide bonds. They may participate in fatty acyl and cholesterol ester metabolism, and may play a role in the blood-brain barrier system. This enzyme is the major liver enzyme and functions in liver drug clearance. Mutations of this gene cause carboxylesterase 1 deficiency. Three transcript variants encoding three different isoforms have been found for this gene.
