| Folic Acid

Folic acid(Folate), also known as vitamin B9 and folacin,is one of the B vitamins.Manufactured folic acid, which is converted into folate by the body, is used as a dietary supplement and in food fortification as it is more stable during processing and storage.Folate is required for the body to make DNA and RNA and metabolise amino acids necessary for cell division and maturation of blood cells.As the human body cannot make folate, it is required in the diet, making it an essential nutrient.It occurs naturally in many foods.
 

| 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	0.216	0.298	0.417	0.669	0.955	1.405	1.79	1.865

 

| Repeatability

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

| Recovery

The recovery of Mouse Folic Acid 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)	81-101	96
Plasma(n=8)	92-105	101
Cell Culture Supernates(n=8)	97-108	105

 

| Linearity

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

 

		Serum(n=4)	Plasma(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	83-95	88-96	90-110
	Average (%)	91	92	96
1 : 4	Range (%)	89-104	87-108	105-115
	Average (%)	93	98	110
