Rabbit anti DNA PKcs antibody recognizes the human DNA-dependent protein kinase catalytic subunit, also known as DNA-PKcs, DNPK1 or p460. DNA PKcs is a 4128 amino acid ~460 kDa nuclear protein encoded by the PRKDC gene, acting as a molecular sensor for DNA damage. Mutation of the PRKDC gene can result in Immunodeficiency 26 with or without neurologic abnormalities (IMD26) (van der Burg et al. 2009).

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.

This product has been reported to work in the following applications. This information is derived from testing within our laboratories, peer-reviewed publications or personal communications from the originators.

  1. 1This product requires heat mediated treatment of paraffin sections. Bio-Rad recommend the use of antigen unmasking fluid for this purpose. A two hour incubation with AHP318 is recommended.
Where this antibody has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the antibody for use in their own system using appropriate negative/positive controls.
