| ATGL

Adipose triglyceride lipase, also known as patatin-like phospholipase domain-containing protein 2 and ATGL, is an enzyme that is encoded by the PNPLA2 gene. ATGL catalyses the first reaction of lipolysis,[8] where triacylglycerols are hydrolysed to diacylglycerols. ATGL has very high substrate specificity for triacylglycerols.[10] It contains a catalytic dyad using serine-aspartic acid.
 

| 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.

 

Concentration (ng/mL)	20	10	5	2.5	1.25	0.625	0.312	0
OD	2.36	1.36	0.8	0.48	0.34	0.26	0.22	0.09
Corrected OD	2.27	1.27	0.71	0.39	0.25	0.17	0.13	-

 

| Repeatability

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

| Recovery

The recovery of Human ATGL 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)	84-101	96
Cell Culture Supernates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human ATGL 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 (%)	88-96	90-110
	Average (%)	93	96
1 : 4	Range (%)	87-108	105-115
	Average (%)	98	108
