Plasmids & Vector Resources

Addgene is a non-profit organization dedicated to making it easier for scientists to share plasmids. Adgene distributes high-quality published plasmids on behalf of scientists.
Plasmid Information Database (PlasmID) is a central repository for plasmid clone collections and distribution as part of the DF/HCC DNA Resource Core based at the Harvard Institute of Proteomics (HIP).
A collection of cloning vectors of Escherichia coli is kept at the National Institute of Genetics as a resource for the biological research community.

The Molecular Biology Vector Sequence Database
VecScreen is a system for quickly identifying segments of a nucleic acid sequence that may be of vector origin developped by the NCBI
EBI tool is based on NCBI BLAST2 and uses the latest implementation of the BLAST algorithm and a special sequence databank known as EMVEC. EMVEC is an extraction of sequences from the SYNthetic division of EMBL containing more than 2000 sequences commonly used in cloning and sequencing experiments.
