DESCRIPTION

KCND3 gene encodes the voltage-gated potassium ion channel subfamily D member 3, a six trans-membrane protein (Kv4.3), involved in the transient outward K+ current. KCND3 gene defect causes both cardiological and neurological syndromes. Kv4.3 contributes to the cardiac transient outward potassium current (Ito1), the main contributing current to the repolarizing phase 1 of the cardiac action potential.

PRINCIPLE OF THE ASSAY

Sandwich ELISA structure (Detection antibody labeled with HRP) A capture antibody is pre-coated onto the bottom of wells which binds to analyte of interest. A detection antibody labeled with HRP also binds to the analyte. TMB acts as the HRP substrate and the solution color will change from colorless to blue. A stop solution containing sulfuric acid turns solution yellow. The color intensity is proportional to the quantity of bound protein which is measurable at 450 nm with the correction wavelength set at 630 nm.

PRECISION

Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested 8 times on one plate to assess intra-assay precision. Inter-assay Precision (Precision between assays) Three samples of known concentration were tested in 16 separate assays to assess inter-assay precision.

Intra-assay Precision

Sample	n	Mean (pg/mL)	SD	CV%
1	8	525.2	13.1	2.5
2	8	120.6	9.0	7.5
3	8	61.4	2.5	4.1

Inter-assay Precision

Sample	n	Mean (pg/mL)	SD	CV%
1	16	513.4	25.9	5.0
2	16	120.7	7.9	6.6
3	16	60.8	2.7	4.4

RECOVERY

The recovery of human human/rat spiked to three different levels throughout the range of the assay in tissue lysate was evaluated.

Sample Type		Average% of Expected	Range (%)
Tissue lysate	1:64	91	82-102

LINEARITY

To assess the linearity of the assay, samples were diluted with the appropriate Sample Diluent to produce samples with values within the dynamic range of the assay. (The tissue lysate was initially diluted 1:4. )

		Tissue lysate
1:2	Average% of Expected	100
	Range (%)	-
1:4	Average% of Expected	85
	Range (%)	74-94
1:8	Average% of Expected	75
	Range (%)	70-83
1:16	Average% of Expected	94
	Range (%)	80-116
