| LPCAT3

Lysophospholipid acyltransferase 5 is an enzyme that is encoded by the LPCAT3 gene.It is homologous to other membrane-bound O-acyltransferases.Based on the crystalographic and cryo-EM studies of its homolog in chicken (cLPCAT3),humane MBOAT5 has a typical MBOAT folding as other members such as SOAT1 and DGAT1,and the transmembrane helices hold a "T"-shape reaction chamber allowing the co-occupancy of a lysophosphatidylcholine (lysoPC) and a long polyunsaturated acyl-CoA, such as arachidonic acyl CoA. Inhibition of LPCAT3 has been found to alter the cellular lipidome and is partially protective against ferroptosis.
 

| 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)	40	20	10	5	2.5	1.25	0.625	0
OD	2.22	1.56	0.92	0.63	0.42	0.25	0.18	0.08
Corrected OD	2.14	1.48	0.84	0.55	0.34	0.17	0.1	-

 

| Repeatability

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

| Recovery

The recovery of Human LPCAT3 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	84-101	96
Plasma(n=8)	92-105	102
Tissue Homogenates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human LPCAT3 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Tissue Homogenates(n=4)
1 : 2	Range (%)	84-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-115
	Average (%)	94	98	108
