| FFAR3

Free fatty acid receptor 3 (FFAR3, also termed GPR41) protein is a G protein coupled receptor (i.e., GPR or GPCR) that encoded by the FFAR3 gene (i.e., GPR41 gene).GPRs reside on cell surfaces, bind specific signaling molecules, and thereby are activated to trigger certain functional responses in their parent cells. FFAR3 is a member of the free fatty acid receptor group of GPRs that includes FFAR1 (i.e., GPR40), FFAR2 (i.e., GPR43), and FFAR4 (i.e., GPR120).All of these FFARs are activated by fatty acids. FFAR3 and FFAR2 are activated by certain short-chain fatty acids (SC-FAs), i.e., fatty acids consisting of 2 to 6 carbon atoms whereas FFFAR1 and FFAR4 are activated by certain fatty acids that are 6 to more than 21 carbon atoms long.Hydroxycarboxylic acid receptor 2 is also activated by a SC-FA that activate FFAR3, i.e., butyric acid.

| Repeatability

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

| Recovery

The recovery of Mouse FFAR3 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)	92-105	102
Cell Lysates(n=8)	96-108	102

 

| Linearity

Samples were spiked with high concentrations of Mouse FFAR3 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

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