How should I store the serum / antisera?
• For short-term storage of the working antibody or of serum that has recently arrived, 2-3 weeks at 4°C is recommended. For long-term storage, we recommend storing the serum vials at -20°C, which is sufficient for several years. Storage at -80°C is fine also, but not necessary except for very long periods of time. The purified antibody should be aliquoted into working quantities and stored according to the guidelines above. The biggest threat to antibody stability is repeated freeze/thaw cycles. To avoid this, we recommend storing ready-to-use aliquots of the antibody and thawing aliquots only as they are needed. We also recommend the use of manual defrost freezers rather than frostless freezers. For more information, please visit our Antibody Storage page.
