==General Information==
A few general details about arabinose can be found on the wikipedia [[Wikipedia:Arabinose|page]]. In biology, arabinose is often used to induce the P<sub>BAD</sub> promoter described [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=12080425&query_hl=3 here]. Concentrations in the range 0.001% - 1% are typically used to produce a range of transcription rates from the P<sub>BAD</sub> promoter.
