LIC Generator, a resource to generate primers for Ligation Independent Cloning (LIC) | [ Mirror site ]

This program generates the sequence of a set of 4 primers to amplify both insert and vector for LIC cloning.
Easily introduce tags or protease cleavage sites in your vector/insert.

LIC requires only three steps Compact display

1- Choose your LIC1 sequence (5' to your insert)

check one or several boxes

*Kozak means that a Kozak consensus is present before the Start
*Linker means that a Ser-Ala linker was added for example between the initiation Met and the tag
