| FⅤ

Coagulation factor V (Factor V), also less commonly known as proaccelerin or labile factor, is a protein involved in coagulation, encoded by F5 gene. It is genomically related to the family of multicopper oxidases, and is homologous to coagulation factor VIII. The gene spans 7 kb, consists of 25 exons, and the resulting protein has a relative molecular mass of approximately 33kDa. In contrast to most other coagulation factors, it is not enzymatically active but functions as a cofactor. Factor V deficiency leads to predisposition for hemorrhage, while some mutations (most notably factor V Leiden) predispose for thrombosis.
 

| 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 (pg/mL)	2000	1000	500	250	125	62.5	31.25	0
OD	2.15	1.7	1.2	0.77	0.43	0.23	0.14	0.04
Corrected OD	2.11	1.66	1.16	0.73	0.39	0.19	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 FⅤ spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Plasma(n=8)	92-105	102

 

| Linearity

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

 

		Plasma(n=4)
1 : 2	Range (%)	88-96
	Average (%)	93
1 : 4	Range (%)	87-108
	Average (%)	97
