Quick Overview

Bacterial recombination protein that enhances interaction and exchange of homologous DNA strands

* Required Fields

Price From: $67.00



  • A 37,8 kDa protein encoded by the recA gene of E coli.
  • Involved in DNA renaturation and rare cleavage of genomic DNA.
  • Ultrapure recombinant protein.


  • Regulates repair mechanisms and repairs DNA (1, 2).
  • Binds cooperatively and stechiometrically to single-stranded DNA.
  • In presence of ATP-g-S, locates and pairs a single-stranded DNA sequence to its homologous double-stranded DNA.
  • Cleaves large fragments of DNA (RARE-Rec A Assisted Restriction Endonuclease) (3).
  • Enhances contrast of electron micrography when DNA is coated with Rec A Protein (4).

Storage Buffer

20 mM Tris-HCl (pH 7.5 at 22°C)
1 mM dithiothreitol
