Plasmid editor · iPhone, iPad and Mac
Every construct, drawn clearly.
Open a GenBank or SnapGene file and PlasmidsX draws the map, finds the cut sites and lays out every base with its annotations. Plan a digest or a Gibson assembly before you go to the bench.
Editing and cloning with PlasmidsX Pro.
Sequence
Every base, with what it means.
Both strands, the translation and the cut sites line up base for base. Here is the multiple cloning site of pEGFP-N1, right before the EGFP start codon.
A keyboard for DNA
Type, paste and cut bases. Features stretch and shrink with your edits, and you're warned when an edit breaks a coding sequence.
Primers that know their Tm
Melting temperatures from SantaLucia nearest-neighbor values, with salt and Mg²⁺ corrections. Keep a shared primer library.
Search inside sequences
Find a motif on either strand, or jump straight to a position. Search also reaches into every plasmid in your library.
Digest & Gel
Run the gel before you pour it.
Choose enzymes and PlasmidsX cuts the plasmid and runs the fragments next to a real ladder. Sites blocked by Dam or Dcm methylation are flagged, so a missing band doesn't surprise you.
Cloning · Pro
Assemble it on screen first.
Cut the vector, add an insert and watch the junctions form. Annotations carry across into the product, and the result keeps a record of where it came from.
On iPhone
Five tabs for one plasmid.
Map, Features, Enzymes, Sequence and Tools. Scroll sideways to see them.
iPad and Mac
Room for the whole construct.
On iPad and Mac the library, the map and an inspector sit side by side. Select a feature, a primer or a cut site and its details and actions are right there.
- Several plasmids open at once, each in its own tab or window
- Drag and drop files in and out, keyboard shortcuts and Apple Pencil
- Your library syncs through iCloud, with a Home Screen widget
Plans
Free to explore. Pro when you build.
