Product overview
Human Thymidine Kinase 1 ELISA Kit (ab223595) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Thymidine Kinase 1 protein in cell culture supernatant, cit plasma, edta plasma, serum, and cell culture extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Thymidine Kinase 1 with 6.1 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells stripsA 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Notes
Thymidine kinase 1, or TK1, is a 234- amino acid, zinc binding protein encoded by the Thymidine Kinase 1 gene. The primary function of Thymidine Kinase 1 is the phosphorylation of thymidine to form deoxythymidine 5’-phosphate, dTMP, and is necessary for DNA replication. The activity of Thymidine Kinase 1 is highest during the S phase of cells, and lowers during the G2 phase. Two forms of Thymidine Kinase 1 have been identified, one in the cytosol and the other in mitochondria, which is known as TK2. The presence of Thymidine Kinase 1 in serum may be a biomarker for certain types of cancer.

Interpolated concentrations of native Thymidine Kinase 1 in human PC3, MCF7, and SH-SY5Y cell extracts.
Interpolated concentrations of native Thymidine Kinase 1 in human PC-3, MCF7, and SH-SY5Y cell extracts based on a 16 μg/mL extract load. The concentrations of Thymidine Kinase 1 were measured in duplicate and interpolated from the Thymidine Kinase 1 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Thymidine Kinase 1 concentration was determined to be 1251 pg/ml in PC-3, 585 pg/mL in MCF7, 721 pg/mL in SH-SY5Y.

Interpolated concentrations of spiked Thymidine Kinase 1 in human serum, plasma and cell culture supernatant samples.
The concentrations of Thymidine Kinase 1 were measured in duplicates, interpolated from the Thymidine Kinase 1 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 50%, plasma (citrate) 50%, plasma (EDTA) 25% and HUVEC supernatant 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).
