Cell-Based Assay Data: Key to Evaluating Functional and Biochemical Effects

Cell-based assays are assays that use live cells to offer a relevant representation of a real-life model, promoting focused biological progress development. This allows for the tracking of dynamic variables such as the number of cells or their behavior. Cell-based assays can be used to evaluate a variety of functional and biochemical effects, including cell proliferation, apoptosis and cell death, signal transduction, enzyme activity, reporter gene activity, antibody-dependent cell-mediated Cytotoxicity (ADCC) and complement dependent Cytotoxicity, among others. These techniques are used to support neutralizing antibody (NAb) assays, relative potency assays, mechanism of action studies and drug combination analysis, to name a few.

Because live cells are used, cell-based assays provide a functional read-out of compound activity, or produce results that are more biologically relevant or have physiological relevance.

BioAgilytix Cell-Based Assay Services: Driven By Scientific and Regulatory Experts

The complexity involved in live cell analysis demands an advanced level of bioanalytical skill and knowledge – not just for the assay itself, but for the regulatory parameters that assay must uphold. With our scientific staff averaging 15+ years of experience developing and performing cell-based assays, BioAgilytix is uniquely qualified in this capacity.

Our team has vast experience with primary cells and transfected reporter-gene cell systems, and can develop and validate cell-based assays under GxP In fact, our scientists were responsible for lead optimization and mechanism-of-action studies that led to the discovery of several key drugs that are on the market today, as well as a number of promising clinical candidates.

We offer custom cell culture including primary explants, cloning, and optimizing expression of a cell line or development of the optimum medium, including serum-free medium. Additionally, purification of your protein can be performed from either cell extracts or the conditioned media.

There are numerous opportunities to utilize cell-based assays in support of the development of biologic breakthroughs.

Cell Proliferation

Cell-based assays can be used for cell proliferation studies assessing cell number increases resulting from cell growth and division.

Apoptosis and Cell Death

Cell-based assays are also used to analyze cell cycle machinery and signaling pathways that control cell arrest and programmed cell death.

Signaling and Secretion

Aiding in the understanding cellular activities and coordination, cell-based assays can be used to assess errors in cellular information processing, and provide insight into how to effectively treat the diseases caused by those errors.
