LINA is a free software system for Windows that was developed to assist research laboratories in keeping track of their collections of biologically relevant materials, including oligonucleotides, bacterial (plasmid) strains, yeast strains and cell lines. Samples are then organized in freezer boxes according to those numbers and users can search the database by keyword, source and function.Basically, the LINA system was developed to allow academic laboratories to efficiently manage their inventory of specialized molecular biology reagents. A LINA’s most useful feature is a tool to search and compare DNA sequences. This means that you can enter a gene sequence and check whether the library contains any oligonucleotides that could be used to amplify it, rather than just ordering new ones.
