Copio dal sito SIGMA Storage/Stability Solutions at 1 mg/ml in buffer or culture medium are stable for approximately one month at 2-8 °C. Frozen aliquots can be stored up to 2 years. Repeated freeze/thaw cycles are not recommended. Solutions should be stored in silanized containers, since LPS can bind to plastics and certain types of glass (especially at concentrations of <0.1 mg/ml). If the LPS concentration is >1 mg/ml, adsorption to the sides of the vial is negligible. If glass containers are used, solutions should be vortexed for at least 30 minutes to redissolve the adsorbed product. |
