Chlorella virus IL-3A
Note 1: Purified from E coli strain that carries the cloned cvijRI gene from Chlorella virus IL-3A (Patent No. US005472872A)

Reagents Supplied

10X CviJ I Reaction Buffer


  • CviJ I is the only available restriction endonuclease recognizing two-three base pair sequence (1,2,3), thus allowing for new research applications (4)
  • This recombinant version of CviJ I cleaves only PuGCPy sites (4)
  • Suitable for high resolution mapping of short DNA's like amplified products or small plasmids
  • Other CviJ I applications, like shotgun cloning, thermal cycle labeling (5) or epitope mapping can be performed either with this version or with CviJ I*
  • Exclusively from CHIMERx
