How long is Sephadex G150 shelf time? We have one bottom of Sephadex G150 in our lab. The bottom looks very old. I swelled the beads and when I prepared the column a lot of beads came out of the column. The column is brand new and this is the first time I used the column. The column is supposed to hold beads larger than 20 micron. Any suggestions? Do I need to buy new Sephadex? or something wrong with the column preparation. Thanks alot
【在 f******e 的大作中提到】 : it is old so i want to know whether Sephadex degraded. BTW where to buy : Sephadex. It looks like they do not sell dry beads only slurry now.
