This web page lists suppliers providing cloning and expression vectors, and cDNA and microRNA clones.  The list is compiled from a systematic manual survey conducted by Labome covering over 60000 randomly selected publications (read  how Labome selects the articles).  This list includes suppliers whose products have been cited in at least one publications. Up to five most cited products for each supplier are displayed.  Therefore, this list provides a comprehensive representation of high-quality suppliers in this product category.  A small number of high-quality suppliers without any citation may also be included; they are not accompanied by any citation data. As the Labome survey is ongoing, this list is updated regularly to reflect the most recent data. Please note: a few companies have been  purchased by or merged with other companies, they remain on the list if their brands are maintained by the new entities, such as Life Technologies, Sigma-Aldrich.  
The total number of citations for cloning and expression vectors, and cDNA and microRNA clones is 197227 from 56435 publications.
