I was wondering if anybody knows about a source that we can order commercial antibodies without Sodium Azide?
I understand that we can use dialysis to remove that but I wanted to know if ordering the antibodies without anti-bacterial is an option?
Thanks!
I have seen thimerosal also like Tomás Allende and I have also called the vendor and asked for the sodium azide-free version which was not in the online catalog, but that was from a purified IgG made from pooled human sera.
Many companies can give you a azide-free or other 'custom' formulation, just give them a call. They may charge a fee for this, so dialysis may be your most economical option.
If you cant get an azide-free version, I would suggest micro "spun" columns rather than dialysis (packed with sephadex G25). They will remove low molecular weight compounds in 5 minutes without substantially diluting the sample. Dialysing the ~50uL sample that you get from teh company would be tricky!!
