L-Azidohomoalanine HCl salt is an amino acid analog that provides a fast, sensitive, non-toxic and non-radioactive alternative to the traditional radioactive 35S-methionine for the detection of nascent protein. L-azidohomoalaine contains a small modification and its azido moiety can be fed to cultured cells and incorporated into proteins during active protein synthesis.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
