The biotinylated single-stranded λ-DNA (48,548 bp) is ideal molecules that specifically bind single-stranded DNA. Exposing the DNA to fluorescently labeled proteins enables you to see dynamic binding activities and quantify DNA-associated events, such as replication, repair, organization, or transcription.

λ-DNA is shipped as nick-free double-stranded DNA. After applying force to the overstretching regime, one of the strands falls off and a single strand remains bound between the beads.

  • Estimated for 2 weeks of measurements
  • Estimated 1–3 weeks delivery time


20 µl – 20 ng/µl (typical dilution factor 1:1000) single-stranded bacteriophage λ-DNA (48,502 bp). Labeled with multiple biotins on the 3′ and the 5′ ends of one of the strands, diluted in TE buffer (10 mM Tris HCl pH 8.0 and 1 mM EDTA).
