Meridian Launches TRUBlock® ULTRA
A Powerful Immunoassay Interference Blocker

TRUBlock® ULTRA (Cat# 8000) is Meridian's new next-generation active HAMA blocker. It is the result of years of R&D aimed at creating the most powerful immunoassay interference blocker in the market.

TRUBlock® ULTRA works over several assay types and blocks interference created by HAMA, rheumatoid factor (RH) and heterophilic antibodies (HA). Its blocking effectiveness has been proven in both ELISA and Lateral Flow assay formats and the broad coverage of TRUBlock® ULTRA against HA/RF allows IVD manufacturers to use this active blocker at reduced concentrations and achieve higher assay performance.

About Blockers
Blockers are used in ELISA and Lateral Flow assays to improve their sensitivity and specificity. Double mouse monoclonal assays and competitive assays are specifically prone to HA interference and require a specialized blocker to ensure the assay’s accuracy. A HAMA blocker such as TRUBlock® ULTRA, contains a specific binder directed against all types of heterophilic interference including HAMA and RF. Once bound to the interfering antibodies, the HAMA blocker prevents further binding of HA to other assay components through steric hindrance.
