LaneStudio
Check the text draft against the original, especially Greek letters. Your figure changes only when you apply the edited text.
Your uploaded image is kept unchanged. Compare the lettering, lane shapes and molecular-weight scales with your working copy.
One line per lane, from left to right. Paste a list of sample names or correct recognized text. Blank lines keep a lane unnamed.
Your current image, lanes, labels, and edits will be cleared. Export anything you want to keep first. This cannot be undone.
