Lyophilized Antibodies

Freeze-dried format for longer shelf life and simplified shipping

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.

How it works

Freeze-drying removes water under vacuum

Lyophilization freezes the antibody solution and then reduces the surrounding pressure so that the frozen water sublimes directly from solid to gas. The resulting dry powder is reconstituted with the recommended diluent before use. Gentle mixing or rocking dissolves the powder fully; shaking is avoided as it can cause foaming and damage the antibody.

Category benefits

Why use lyophilized antibodies?

✓	Reconstitute before use Add 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 frozen Left unopened and stored frozen, the freeze-dried format can remain stable for years without losing activity.
✓	Avoids freeze-thaw damage before use Because it stays dry until reconstitution, the antibody is not exposed to repeated freeze-thaw cycling that can degrade a liquid stock over time.
✓	Simplified shipping and reduced cold-chain costs Lyophilised antibodies can be shipped at ambient temperatures without compromising stability, lowering shipping expenses and simplifying international logistics compared to liquid formats that require strict temperature control.
✓	Cost-effective and minimal waste Reconstitute only the precise volume needed for your experiment while the remaining dry powder stays stable, reducing reagent waste and maximising the value per vial over the long term.
