Cloning vector necklace | 18K gold vermeil
The Cohen-Boyer 1973 experiment that founded recombinant DNA biology used a small bacterial plasmid as the vector, the iconic circular structure that has been the working object of molecular biology ever since. The 18K gold vermeil version of the cloning vector, at 20 mm, the milestone-gift companion to the silver pendant and earrings.
The Science Behind the Cloning Vector
A cloning vector is a small circular DNA molecule used to carry foreign genetic material into a bacterial host for replication and study. The vector carries an origin of replication, a selectable marker like antibiotic resistance, and a multiple cloning site with restriction enzyme recognition sequences for inserting the gene of interest. Stanley Cohen and Herbert Boyer's 1973 paper in PNAS, ligating tetracycline-resistance fragments into the pSC101 plasmid and recovering them from E. coli, was the founding moment for recombinant DNA biology. pBR322 (1977) and pUC19 (1985) followed as standard research workhorses. Modern descendants include shuttle vectors that cross between bacterial and mammalian hosts, expression vectors with strong promoters for protein production, and lentiviral vectors for stable mammalian integration. The plasmid map is the working object of any molecular biology lab and the conceptual foundation under most of modern biotechnology.
A Quiet Symbol For
- molecular biologists and biotechnologists at career milestones
- protein expression scientists and biopharmaceutical researchers
- genetics educators retiring from a long teaching career
- partners and family of working scientists looking for a meaningful gold gift
Most often given on a milestone in molecular biology or biotech, where the gold version reads as recognition for someone whose career has been spent designing, building, and reading plasmid maps.

FAQ
Why pick the gold cloning vector over the silver?
The most common reason is the milestone framing. Gold reads as recognition where silver reads as daily wear. Same 20 mm pendant, same chain length, same plasmid map. The choice is about what the gift is meant to mark, not what cloning vectors do in a working molecular biology lab. Often given at the retirement of a senior molecular biologist, or at the end of a long career running a core facility or a biotech R&D group.
Why has the cloning vector remained iconic when CRISPR has changed gene editing?
Because most CRISPR experiments still depend on plasmid vectors to deliver Cas9 and the guide RNA, and a substantial fraction of molecular biology runs on cloned constructs that have nothing to do with gene editing: protein expression, reporter assays, library construction, recombinant antibody production, vaccine development. The cloning vector predates CRISPR by forty years and continues to underpin the workflows that CRISPR sits on top of. The two are complements. The plasmid is the working scaffold. CRISPR is one of the things built on top of it.
What size is the pendant and what chain comes with it?
18K gold vermeil over a sterling silver core, 20 mm pendant on a 45 cm gold vermeil chain with a 5 cm extender. Smaller scale than most pieces in the catalogue, sits as a quiet daily-wear pendant rather than a statement piece. Nickel-free and hypoallergenic. Free worldwide DHL Express in 1-5 business days, with all import duties and taxes covered. 30-day “Love It or Return It” returns.
Is there a silver version, or matching earrings?
Both. The cloning vector is available as a sterling silver pendant at the same 20 mm scale and as silver leverback earrings. The three formats often go together as a graduation set for a senior molecular biologist, or as a gift across two people who share a lab.
