Was looking into L-DNA (re: storage, mirror, helix, barcoding) and found an article with the symbol in the pic. The symbol comes up as Lambda – upon further investigation, I found there is a Lambda-DNA bacteriophage (phage) discovered in 1950. Having a bit a trouble tying it all together, but there seems to be a lot of genetic engineering/cloning going on with phages. Maybe these are where the scariants are coming from?

L-DNA offers new twist on information storage

Life can look very different in a mirror. DNA’s famous double helix normally has a right-handed twist, for example, but its reflection corkscrews the other way, forming a left-handed helix called L-DNA.

Our long term goal is to build a mirror-image ribosome, to realize the mirror-image central dogma

We realize chiral steganography by embedding a chimeric d-DNA/l-DNA key molecule in a d-DNA storage library, which conveys a false or secret message depending on the chirality of reading. Furthermore, we show that a trace amount of an l-DNA barcode preserved in water from a local pond remains amplifiable and sequenceable for 1 year, whereas a d-DNA barcode under the same conditions could not be amplified after 1 day.

Bacteriophages such as lambda phages can also be used as effective vectors for transferring recombinant DNA molecules into cells for cloning.

Phages re: exotoxin produced by Staphylococcus aureus

As expected, the corresponding enantiomeric L-DNA Spiegelmer showed comparable binding characteristics to the L-peptide domain. Moreover, the Spiegelmer bound the whole protein target with only slightly reduced affinity. Dissociation constants of both peptide-oligonucleotide complexes were measured in the range of 200 nM, whereas the Spiegelmer binding to the full-length protein was determined at approximately 420 nM. These data demonstrate the possibility to identify Spiegelmers against large protein targets by a domain approach.

Staphylococcal enterotoxin B (SEB) is an exotoxin produced by Staphylococcus aureus. It is one of the toxins responsible for staphylococcal food poisoning in humans and has been produced by some countries as a biological weapon. SEB is a superantigen; it acts by stimulating cytokine release and inflammation.
