| MMRN1

Multimerin 1, also known as elastin microfibril interfacer 4 (EMILIN-4), is a protein that is encoded by the MMRN1 gene.Multimerin is a massive, soluble protein found in platelets and in the endothelium of blood vessels. It is composed of subunits linked by interchain disulfide bonds to form large, variably sized homomultimers. Multimerin is a factor V/Va-binding protein and may function as a carrier protein for platelet factor V. It may also have functions as an extracellular matrix or adhesive protein. Recently, patients with an unusual autosomal-dominant bleeding disorder (factor V Quebec/Quebec Platelet Disorder) were found to have a deficiency of platelet multimerin.
 

| 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)	100	50	25	12.5	6.25	3.12	1.56	0
OD	2.36	1.7	1.26	0.87	0.6	0.4	0.28	0.09
Corrected OD	2.27	1.61	1.17	0.78	0.51	0.31	0.19	-

 

| Repeatability

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

| Recovery

The recovery of Human MMRN1 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)	85-101	96
Cell Culture Supernates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human MMRN1 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	84-95	90-110
	Average (%)	91	96
1 : 4	Range (%)	89-103	105-115
	Average (%)	94	108
