Lyophilized antibodies are freeze-dried: water is removed from the frozen antibody solution under vacuum, leaving a stable solid rather than a liquid. This format eases shipping temperature requirements and extends shelf life, and the antibody is reconstituted in buffer before use.
St John's Laboratory lists 2,985 lyophilized antibodies, supplied as a freeze-dried solid rather than in liquid buffer.
Reconstitute before useAdd the recommended diluent, then gently mix or rock the vial until the powder is fully dissolved rather than shaking it, which can cause foaming and damage the antibody.
Longer shelf life when stored frozenLeft unopened and stored frozen, the freeze-dried format can remain stable for years without losing activity.
Avoids freeze-thaw damage before useBecause it stays dry until reconstitution, the antibody isn't exposed to the repeated freeze-thaw cycling that can degrade a liquid stock over time.
Applications
Applications
Immunohistochemistry (IHC) is by far the most common validated application in this range, alongside immunocytochemistry (ICC), flow cytometry (FC), immunofluorescence (IF) and ELISA.
Monoclonal options give you a single, consistent epitope for repeat experiments, while polyclonal options bind multiple epitopes on the target for stronger signal detection.
