It’s so easy to switch.

Our DNASTAR support team has successfully transitioned thousands of former Vector NTI customers to SeqBuilder Pro. With prices as low as $99, it’s the perfect time for you to make the switch!

DNASTAR lets you import Vector NTI databases with ease, including folders and files; DNA, protein and primer sequences. Your folder and file structures and sequence annotations will be preserved.

SeqBuilder Pro is an established Vector NTI alternative and has supported exported and archived Vector NTI data (.gb, .gp, .ma4, .oa4 and .pa4) for over ten years.

And it’s easy to learn, too!

SeqBuilder Pro’s all-new user guide features illustrated step-by-step instructions with integrated tutorials and “how to” videos. You’ll be rocking your favorite workflows in record time.

A bounty of popular workflows

The perfect alternative to Vector NTI, SeqBuilder Pro leads the field in sequence analysis, plasmid map creation, cloning, primer design, and much more.

Primer Design

Create customized primer pairs, frame genes, modify primers, create PCR inserts for TA cloning.

Automated Virtual Cloning

Gateway, Gateway multisite, Gibson, GeneArt, Infusion, TA, TOPO (topoisomerase cloning), PCR-directed restriction cloning

Sanger Clone Verification

Visualization of aligned Sanger data, interactive variant report, fast and accurate alignment of Sanger data.

Sequence Editing

Edit the sequence and features, then create custom, publication-quality images.

We support VNTI files (.gb, .gp, .ma4, .pa4)!

Automated Plasmid Annotation

Automatically update feature annotations for one or many sequences simultaneously from our curated feature library

Agarose Gel Simulation

Replace manual plotting of DNA fragment mobility with this easy, customizable digital simulation.
