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. |
