NaI (Sodium Iodide) is supplied with GeneClean kits and helps in binding the DNA to the GLASSMILK binding matrix.
NaI melted 0.1 g gel slice in 5 minutes at 55°C. Less than 15% DNA 1 kb and above is left unbound in NaI.
NaI solution must be kept away from light and open air sources to prevent oxidation. NaI is packaged under nitrogen gas to further reduce chance of oxidation. Purging NaI's bottle with nitrogen gas is a preferred storage method after opening, especially for long-term storage. Ensure that the NaI cap is always very tight. Sealing the cap after opening and during long-term storage is also recommended.
