Scientific Background
The PRKDC gene encodes the catalytic subunit of a nuclear DNA-dependent serine/threonine protein kinase (DNA-PK). The second component is the autoimmune antigen Ku, which is encoded by the G22P1 gene on chromosome 22q. On its own, the catalytic subunit of DNA-PK is inactive and relies on the G22P1 component to direct it to the DNA and trigger its kinase activity; PRKDC must be bound to DNA to express its catalytic properties. The PRKDC protein showed similarity to phosphatidylinositol 3-kinase family members involved in cell cycle control, DNA repair, and DNA damage responses, and had no detec.
Assay Principle
This assay employs a two-site sandwich ELISA to quantitate PRKDC in samples. An antibody specific for PRKDC has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPRKDC present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PRKDC is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PRKDC bound in the initial step. The color development is stopped and the intensity of the color is measured.

Safety & Regulatory
Handle reagents in accordance with institutional biosafety guidelines. Refer to the Safety Data Sheet (SDS) for complete hazard and handling information. Contains components that may require special disposal procedures per local regulations.
This kit is validated for use with serum, plasma, cell culture supernatant, tissue homogenate. For unlisted matrices (e.g., tissue lysate, urine), perform a spike-and-recovery experiment to confirm assay performance before generating reportable data. Sample dilution in the kit's provided diluent is recommended to minimize matrix interference.
The minimum detectable concentration (sensitivity) of this kit is 0.105 ng/mL. Values below this threshold should be reported as below the limit of detection (<LOD) and should not be extrapolated from the standard curve.
The total assay time from sample addition to absorbance reading is approximately 3.5–5 hours, including all incubation, wash, and substrate steps. Hands-on time is typically 1–2 hours; most steps involve passive plate incubation. Plan the assay as a single uninterrupted session for best results.
Standard components of this Sandwich ELISA Kit typically include: pre-coated microplate (96-well strip format), lyophilized or liquid recombinant PRKDC standard, detection antibody, streptavidin-HRP conjugate, TMB substrate, stop solution, wash buffer concentrate, and sample/standard diluent. Refer to the kit insert or datasheet for the exact component list and storage requirements.
This kit uses colorimetric (TMB/HRP) detection and requires a standard microplate absorbance reader capable of measuring at 450 nm. A reference wavelength of 570 nm or 630 nm is recommended to reduce background. No specialized fluorescence or luminescence reader is needed. Ensure the instrument is calibrated and the plate is clean and free of condensation before reading.
