F.A.Q.

Click the question to get your answer

Antibodies can be frozen, but the process of freezing and thawing is damaging for the antibodies, and the titer will drop (even though not dramatically) due to decomposition. We have not made further studies on this, and cannot guarantee the stability of the sera, but we have experienced that mostly the titer stays at the same level if a serum only is frozen and thawn once.

Yes, it is possible, if you place an order in advance with the expected total volume for the period. In return we guarantee to keep the reserved lot for you.

You can always send an inquiry. We might have it. Depending on the needed volume, we might be able to develop the requested product. It can be anything from a new pool composition to a new serum.
