| ACAT1

Acetyl-CoA acetyltransferase, mitochondrial, also known as acetoacetyl-CoA thiolase, is an enzyme that is encoded by the ACAT1 (Acetyl-Coenzyme A acetyltransferase 1) gene.Acetyl-Coenzyme A acetyltransferase 1 is an acetyl-CoA C-acetyltransferase enzyme.This gene encodes a mitochondrially localized enzyme that catalyzes the reversible formation of acetoacetyl-CoA from two molecules of acetyl-CoA.The ACAT1 enzyme has a few unique properties. First, it is activated by potassium ions binding near the CoA binding site and the catalytic site. This binding causes a structural change in the active site loop. Additionally, this enzyme is able to use 2-methyl-branched acetoacetyl-CoA as a substrate, making it a unique thiolase.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Mouse ACAT1 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	91-105	102
Cell Culture Supernates(n=8)	96-108	104

 

| Linearity

Samples were spiked with high concentrations of Mouse ACAT1 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	88-98	90-110
	Average (%)	93	96
1 : 4	Range (%)	87-108	105-115
