Getting Started with PlasmidStudio: From Idea to Validated Construct

PlasmidStudio works differently from traditional design tools. Instead of manually drawing features on a map, you describe what you want in plain English and the AI generates an annotated, validated construct.

This guide walks you through designing your first construct — from login to export.

PlasmidStudio uses magic link authentication — no password needed. Enter your email, click the link in the email you receive, and you're in.

Sign up is open — new accounts start on the Free tier (10 AI requests per day) at no cost. Students with an academic email can verify for free access at 50/day.

From a template: Click "Browse Templates" and choose from 20 curated backbones across mammalian, bacterial, CRISPR, viral, yeast, and Gateway categories. Templates come pre-loaded with appropriate features and expression systems.

From a prompt: Type what you need directly in the chat. Examples: - "Design a mammalian expression vector for GFP with a CMV promoter" - "Create a bacterial expression plasmid for His-tagged protein purification" - "Build a CRISPR construct targeting the BRCA1 gene"

From an existing file: Click "Import" and upload a GenBank (.gb), FASTA, or SnapGene (.dna) file. PlasmidStudio will parse the file and display the construct.

Once your initial construct is loaded, refine it through conversation: - "Add a His-tag to the C-terminus" - "Switch the antibiotic resistance to ampicillin" - "Remove the GFP and add mCherry instead" - "Optimize the codons for E. coli"

Each change updates the plasmid map in real time. The AI explains what it changed and why.

Look at the Design Health panel on the right side. It runs 14 automated checks on your construct: - Reading frame alignment - Missing terminators or polyA signals - Incompatible origins of replication - Restriction site conflicts - Codon usage issues - And more

Green checks mean everything looks good. Yellow warnings and red errors include explanations and one-click fixes. Click "Fix this in chat" to have the AI resolve the issue.

Click "Suggest Cloning Strategy" in the viewer header. The AI analyzes your construct and recommends the best cloning method: - Restriction Enzyme — for simple single-insert cloning - Gibson Assembly — for scarless multi-fragment assembly - Golden Gate Assembly — for standardized multi-part construction - Gateway Cloning — for expression screening across vectors

Click "Open in Wizard" to set up the cloning simulation with primers and fragment visualization.

When your design is ready, click "Generate Protocol" in the chat (or ask the AI: "generate a protocol for this construct"). PlasmidStudio creates a detailed wet lab protocol including: - Materials list with catalog numbers - Step-by-step procedure - Primer sequences with Tm and GC% - Verification strategy (colony PCR, restriction digest, sequencing)

Export the protocol as PDF for your lab notebook.

Export your validated construct in the format you need: - GenBank (.gb) — universal exchange format - FASTA — sequence only - SnapGene (.dna) — compatible with SnapGene and SnapGene Viewer - SBOL v3 (.xml) — for SynBioHub and computational design tools - PDF map — for presentations and lab notebooks - Synthesis export — formatted for IDT, Twist, or GenScript ordering

Click the Export button in the sidebar to access all formats.
