DESCRIPTION

LYVE1 is a 322-amino acid type-I integral membrane glycoprotein primarily expressed on lymphatic endothelial cells. LYVE1 is a CD44 homologue. It acts as a receptor and binds to both soluble and immobilized hyaluronan. LYVE1 may function in lymphatic hyaluronan transport and have a role in tumor metastasis.

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	1,332.3	53.5	4.0
2	8	339.9	14.1	4.2
3	8	96.4	2.3	2.4

Inter-assay Precision

Sample	n	Mean (pg/mL)	SD	CV%
1	16	1,329.7	47.6	3.6
2	16	328.7	16.3	5.0
3	16	94.1	3.5	3.7

RECOVERY

The recovery of human LYVE-1 spiked to three different levels throughout the range of the assay in human serum was evaluated.

Sample Type		Average% of Expected	Range (%)
Cell lysate	1:3,200	97	91-111

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 human serum was initially diluted 1:200. )

		Human serum
1:2	Average% of Expected	100
	Range (%)	-
1:4	Average% of Expected	90
	Range (%)	88-91
1:8	Average% of Expected	91
	Range (%)	90-93
1:16	Average% of Expected	88

CALIBRATION

This immunoassay is calibrated against a highly purified recombinant human LYVE-1 produced at Sunlong Medical™.
