发帖数: 125 | 1 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 |
