| UCK2

Uridine-cytidine kinase 2 (UCK2) is an enzyme that is encoded by the UCK2 gene.The protein encoded by this gene catalyzes the phosphorylation of uridine and cytidine to uridine monophosphate (UMP) and cytidine monophosphate (CMP), respectively. This is the first step in the production of the pyrimidine nucleoside triphosphates required for RNA and DNA synthesis. In addition, an allele of this gene may play a role in mediating nonhumoral immunity to Hemophilus influenzae type B.
 

| 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)	10	5	2.5	1.25	0.625	0.312	0.156	0
OD	2.15	1.46	0.87	0.6	0.39	0.28	0.21	0.09
Corrected OD	2.06	1.37	0.78	0.51	0.3	0.19	0.12	-

 

| Repeatability

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

| Recovery

The recovery of Human UCK2 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	93-105	102
Cell Culture Supernates(n=8)	96-108	104

 

| Linearity

Samples were spiked with high concentrations of Human UCK2 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	88-96	92-110
	Average (%)	93	96
1 : 4	Range (%)	87-108	105-115
	Average (%)	100	108
