Vector NTI is a commercial bioinformatics software package used by many life scientists to work, among other things, with nucleic acids and proteins in silico. It allows researchers to, for example, plan a DNA cloning experiment on the computer before actually performing it in the lab.

It was originally created by InforMax Inc, North Bethesda, MD. Initially released for free, it was locked and turned into a commercial software after 2008 which created problems for locked in users who were forced to buy the software to continue accessing their data on newer computers.
What was previously a single software package has been split into Vector NTI Express, Advanced, and Express Designer.
Vector NTI has been discontinued by its corporate parent Thermo Fisher. Support will cease as of December 31, 2020.
