Cell-based Assays

IBR Inc. has a longstanding experience in development, validation and operating cell-based assays. Our special expertise are bioassays using primary cells. These cells are isolated from a broad variety of human or mammalian tissues.

Depending on the application, primary cells are considered to deliver more physiological responses than transformed cell lines. However, primary cells are demanding with regard to cell culture and handling. Our team has vast know-how in management of primary cells to provide you with reliable and precise potency assays as well as mode of action assessments.

In addition, we offer bioassays using transformed cell lines and reporter gene assays. We are capable to assess a broad variety of endpoints like cell growth / death, cell signaling, migration & invasion, adhesion and many more.

With our cell-based assays, we are capable to support your drug developmental program from pre-clinical to clinical development. We also provide our cell-based assays under GLP Quality standards.

IBR Inc. invites you to discuss your special needs with our experts.

Our reporter-gene cell systems

Reporter-gene cell lines are useful tools to analyse the effects of a compound on the activity of a specific promoter linked to a reporter gene that is encoding for a luciferase.

Immortal human type II bronchial epithelial cells that were obtained from lung carcinomatous tissue (A549) or human T lymphocytes obtained from an individual with acute lymphoma (Jurkat) have been stably transfected with vectors containing the neomycin resistance gene, the luciferase sequence and a broad panel of different promoter sequences (see Table below)

IBR Inc. offers development and validation of custom reporter gene assays using these cell lines. These reporter-gene cell lines are ready for out-licensing. To learn more about these products and services please send an E-mail or give us a call.

We have broad experience in developing gene-reporter assays to support drug development of biopharmaceuticals, new small molecule drugs, cosmetics and food additives. In particular, we developed gene-reporter assays that enabled to assess anti-inflammatory and pro-inflammatory effects, allergic side effects as well as detection of previously unknown side effects.
