Lambda DNA/EcoR I Digest, 50 g, 100 loads is a product supplied by Genei. Lambda DNA is isolated from an E.Coli phage lambda cl857 Sam 7, which is a lysogenic phage. The DNA is double-stranded and has about 48,502 base pairs and has a molecular weight of 31.5 * 10^6 Da. Lambda DNA has a special site called cos-site, which is formed by joining of the 3 and 5 overhangs at the cos ends. Lambda DNA, once digested with restriction enzymes, can be used as a molecular weight marker for gel electrophoresis. EcoRI is a type II restriction endonuclease which cleaves the DNA at the palindromic sequence G/AATTC. The Lambda DNA/EcoR I Digest, 50 g, 100 loads from Genei has the following features:

- EcoR I digests the Lambda DNA to yield six fragments which have the following sizes:

21,226 5,643

7,421 4,878

5,804 3,530

- The last 3530 fragment will be procured upon heating the Lambda digest at 65C for 5 minutes followed by cooling.

- The product is supplied in 10 mM Tris-HCl (pH 8.0) and 10 mM EDTA.
