| DNMT1

DNA (cytosine-5)-methyltransferase 1 (Dnmt1) is an enzyme that catalyzes the transfer of methyl groups to specific CpG sites in DNA, a process called DNA methylation. It is encoded by the DNMT1 gene. Dnmt1 forms part of the family of DNA methyltransferase enzymes, which consists primarily of DNMT1, DNMT3A, and DNMT3B.This enzyme is responsible for maintaining DNA methylation, which ensures the fidelity of this epigenetic patterns across cell divisions. In line with this role, it has a strong preference towards methylating CpGs on hemimethylated DNA.However, DNMT1 can catalyze de novo DNA methylation in specific genomic contexts, including transposable elements and paternal imprint control regions.Aberrant methylation patterns are associated with certain human tumors and developmental abnormalities.

| 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	2.14	1.21	0.81	0.53	0.39	0.3	0.25	0.09
Corrected OD	2.05	1.12	0.72	0.44	0.3	0.21	0.16	-

| Repeatability

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

| Recovery

The recovery of Human DNMT1 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)	84-101	96
Cell Culture Supernates(n=8)	96-108	105

| Linearity

Samples were spiked with high concentrations of Human DNMT1 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 (%)	84-95	90-110
1 : 2	Average (%)	91	96
1 : 4	Range (%)	89-103	105-115
1 : 4	Average (%)	94	109
