    PNK Antibody (B-4) is a mouse monoclonal IgG1 antibody that detects polynucleotide kinase (PNK) in human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). Anti-PNK antibody (B-4) recognizes the bifunctional polynucleotide phosphatase/kinase, which plays a crucial role in DNA repair mechanisms, particularly in response to damage from radiation or oxidative stress. PNK (B-4) monoclonal antibody enables detection of a protein essential for maintaining genomic stability, as PNK catalyzes the phosphorylation of DNA at hydroxy termini while also possessing the ability to dephosphorylate 3′-phosphate termini, thereby facilitating the proper processing of DNA ends during repair. PNK is predominantly located in the nucleus, where PNK activity is vital for the repair of single-strand breaks and the maintenance of DNA integrity. The highest expression levels of PNK are found in the testis, pancreas, spleen, kidney, and heart, highlighting PNK importance in various cellular functions and tissue-specific roles. Anti-PNK antibody (B-4) helps researchers gain insights into the dynamics of DNA repair processes and the implications of PNK in cellular responses to DNA damage.

    When should the TransCruz reagent sc-166188 X be used instead of the standard form sc-166188?

    Asked by: Cweed
    Thank you for your question. We recommend using the TransCruz reagent form when performing ChIP or GelShift assays. This form can also be used in other applications such as Western Blot or IHC, but the dilution should be adjusted by a factor of 10 to account for the higher original concentration.
