General description

Hoechst 33258, also known as bisbenzimide, is a fluorescent blue dye. It is categorized as a chromosomal stain that binds to the minor groove of the DNA double helix recognizing a run of four A-T base pairs.

Application

Hoechst 33258 is used to estimate DNA concentration in samples by fluorometry which is better than spectrophotometry, allowing the determination of nanogram quantities of DNA. Also, Hoechst 33258 is suitable to detect mycoplasma contamination in cell cultures due to its high fluorescence ability.

Polynucleotide kinase/phosphatase (PNKP) and X-ray repair cross-complementing 1 (XRCC1) are key proteins in the single-strand DNA break repair pathway. Phosphorylated XRCC1 stimulates PNKP by binding to its forkhead-associated (FHA) domain, whereas nonphosphorylated XRCC1 stimulates PNKP by interacting with the PNKP
