Invitrogen™ λ DNA (cIind 1 ts857 Sam 7)

Invitrogen™ λ DNA (cIind 1 ts857 Sam 7)

λ DNA (cIind 1 ts857 Sam 7) is isolated from a dam+ dcm+ E. coli LE597 lysogen. The DNA is suitable for use as a substrate for generating molecular size standards and for testing restriction endonuclease activity. Restriction endonucleases sensitive to dam or dcm methylation will not cleave this DNA.

Performance and Quality Testing: Purity, DNA structure, and selected restriction endonuclease fragmentation patterns are verified by agarose gel analysis.
