Instant Lambda DNA
from Carolina Biotechnology

Bacteriophages (literally: "bacteria-eaters") are viruses that invade bacteria. Phage lambda is a relatively simple organism. It consists of a double-stranded length of DNA wrapped around a core of protein and encapsulated in a proteinaceous coat. The entire genetic makeup (genome) of lambda has been sequenced and is 48,502 base pairs long. Within this genome are genes that code for the virus's protein coat, bursting (lysis) of the bacterial cell, integration of lambda DNA into the host's chromosome and so on. The order in which these genes are activated is important. For example, it would be of little benefit to the virus if the host bacterial cell was broken open (lysed) before new virus particles had been assembled. Lambda has evolved an elaborate system of gene regulation that has been studied in great detail. Several specially constructed forms of lambda can be used by molecular biologists to ferry new genes into bacteria.

Now, Carolina Biotechnology brings you Lambda DNA freeze-dried in tris-EDTA buffer; stable for years at room temperature. Convenient and easy to use!

Simply add distilled water prior to use!
