Hi, I have this antibody against the protein of my interest which was a gift from another lab so I do not have the possibility of getting it again. The commercial antibodies are not as good as this one and even though I have been using this 'gift' antibody sparingly I think its going bad. I had made the working stock 1:2000 in PBTA (5% BSA + 0.02% NaN3). I see the antibody solution has lately become slightly turbid and there is some small ppt at the bottom. If I filter this, do you think it will help ? I would appreciate your inputs.
Thanks.
