How to Make a Western Blot Figure with AI: Step-by-Step Guide (2026)
Learn how to make a western blot figure with AI step by step — build the SDS-PAGE-to-detection workflow schematic, lay out labeled bands and loading controls, add a kDa ladder and densitometry, and export a publication-ready immunoblot diagram. Template, examples, and fixes for common mistakes.
A western blot figure has two jobs: it explains the method (the workflow from gel to detection) and it presents results (lanes, bands, loading controls, and quantification). Drawing either one by hand is tedious, and a single mislabeled lane or a missing kDa marker can confuse a reviewer. This guide shows you how to make a western blot figure with AI step by step — building a clean workflow schematic, laying out labeled result bands, adding a molecular-weight ladder and densitometry, and exporting a publication-ready immunoblot diagram — no design software and no drawing skills required.
A note up front: use this guide to make schematic illustrations — teaching figures, workflow diagrams, and figure mock-ups. These AI-generated blots do not replace your real experimental blot images; always present your own captured data and densitometry as actual results.
By the end of this guide you'll be able to:
Generate a western blot workflow diagram from SDS-PAGE separation through transfer, blocking, antibody incubation, and detection.
Lay out a western blot result figure with labeled lanes, bands, and a kDa ladder.
Add a loading control and densitometry quantification chart beneath the blot.
Edit and export your figure to editable SVG or PPTX for a paper, poster, or slide deck.
Every step below is done by typing an instruction into the Western Blot Figure Generator, then refining the result in the SciDraw AI editor — the AI-native workspace where your image is the canvas and language is the tool.
Davie Chen is a researcher at the Faculty of Animation and Intermedia, University of Arts in Poznan, studying generative AI for scientific figure creation, patent illustration, and manuscript drafting. SciDraw AI is one of the research-to-product tools built from this work.
Thousands of researchers use SciDraw AI to make publication-ready figures for papers, grants, and journal submissions — in minutes, with no design skills.
Template: "Draw [workflow or result panel] showing [steps or lanes]. Label [proteins, lanes, kDa markers, controls]. Use a clean flat-vector style with a left-to-right flow."
Keep this handy — every example below follows it, and you can swap in your own targets and conditions.
The workflow diagram is the most requested schematic — it walks a reader from gel to signal. Paste this into the Western Blot Figure Generator:
"Draw a western blot workflow as a labeled left-to-right flow with five steps: SDS-PAGE gel separation of proteins by size, transfer of proteins to a membrane, blocking the membrane, incubation with primary then secondary antibodies, and detection of the signal. Label each step and show the membrane and antibodies. Use a clean flat-vector style."
This produces the workflow schematic above — ideal for a methods figure or a lecture slide. From here you can zoom into a single step or branch into the results panel.
"Illustrate antibody detection on a western blot membrane: a primary antibody binding the target protein, an HRP-conjugated secondary antibody binding the primary, and chemiluminescent signal being produced. Label the membrane, target protein band, primary antibody, secondary antibody, and HRP."
Result figures are where reviewers look first. Use this as a schematic mock-up — the layout you'd build before dropping in your real captured data:
"Draw a schematic western blot result panel: three lanes (Control, Treatment 1, Treatment 2) showing a target protein band that increases across lanes, with a loading control (GAPDH) band of equal intensity below. Add a molecular-weight ladder on the left with kDa values labeled. Use a clean flat-vector style — this is a schematic mock-up, not real data."
"Add a GAPDH loading control band below the target protein, equal across all lanes."
"Add a bar chart beneath the blot showing relative band intensity (densitometry) for each lane, normalized to the loading control. Label the y-axis 'Relative expression.'"
"Add the molecular weight in kDa next to the target band and the loading control."
Treating a schematic as real data. Fix: remember these are illustrations — use them for workflow diagrams and figure mock-ups, and present your own experimental blots and densitometry for actual results.
Missing kDa ladder. Fix: ask to "add a molecular-weight ladder on the left with kDa values labeled."
No loading control. Fix: re-prompt with "add a GAPDH loading control band of equal intensity below the target."
Lanes mislabeled or unlabeled. Fix: name each lane condition in the prompt ("Control, Treatment 1, Treatment 2").
Garbled text (typical of generic image AI). Fix: SciDraw AI renders clean sans-serif labels; re-prompt the exact wording if a label looks off.
Once the diagram reads exactly right, export it to editable SVG or PowerPoint (PPTX), or download a high-resolution image for your manuscript, slides, or poster. SVG and PPTX let collaborators adjust a lane label or kDa value later, while the AI editor handles the fast fixes now.
How do I make a western blot figure with AI?
Open the Western Blot Figure Generator, describe the workflow or result panel, name every lane, band, and label, and generate. Then refine the result in the SciDraw AI editor — add a loading control, kDa ladder, or densitometry chart.
Are these AI western blot figures real data or schematics?
They are schematic illustrations for teaching, workflow diagrams, and figure mock-ups — not a replacement for your experimental blot images. Always present your own captured blots and densitometry as actual results.
How do I add a loading control to my western blot diagram?
Tell the editor to "add a GAPDH (or β-actin) loading control band of equal intensity below the target protein, across all lanes." You can add densitometry below it the same way.
Can I make a western blot figure for free?
Yes — you can start generating western blot schematics for free, then upgrade for more credits and editable SVG/PPTX export.
Can I show molecular weights on the blot?
Yes. Ask the AI to "add a molecular-weight ladder on the left with kDa values labeled," and add the kDa next to each band of interest.
Open the Western Blot Figure Generator, paste the workflow prompt above, and refine it in the SciDraw AI editor until it matches your study. From a clean method schematic to a labeled result mock-up, your next western blot figure is one sentence away — just remember to present your own data for actual results.
