Idoxuridine (5-Iodo-2′-deoxyuridine, 5-IUdR, IdUrd) hydrate is an iodinated thymidine analogue that competitively inhibits phosphorylases. Idoxuridine can inhibit viral activity, particularly viral eye infections, including herpes simplex keratitis, by inhibiting DNA polymerase and affecting viral replication. Idoxuridine against feline herpesvirus has the IC₅₀ value of 4.3 μM.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
