text: Many plasmids have been created over the years and researchers have given out plasmids to plasmid databases such as the non-profit organisations [https://www.addgene.org Addgene] and [http://bccm.belspo.be/about-us/bccm-lmbp BCCM/LMBP]. One can find and request plasmids from those databases for research.
  Researchers also often upload plasmid sequences to the [https://www.ncbi.nlm.nih.gov/nuccore/ NCBI database], from which sequences of specific plasmids can be retrieved.
