Therapeutic antibodies have recently emerged as one of the most successful immunotherapy strategies for the treatment of both hematologic cancers and solid tumors.

Functional ex vivo assays that predict a patient's clinical response to anticancer drugs for guiding cancer treatment have long been a goal, but few have yet proved to be reliable. To address this, we have developed an automated flow cytometry platform for drug screening that evaluates multiple endpoints with a robust data analysis system that can capture the complex mechanisms of action across different compounds. This system, called PharmaFlow, is used to test peripheral blood or bone marrow samples from patients diagnosed with hematological malignancies.

Applications of Flow Cytometry in the Drug Development Process

Thus, they are essential for the normal and satisfactory working of the instrument. Calibration reagents are used for validating that the instrument records the values consistent with the actual or real concentration or number of cells. These are proprietary and contain particle concentration in a narrow range. The buffers are used to maintain the pH of the solutions used in flow cytometry. Specificity reagents are used to bind selectively to the sample particles so as to ease detectability. The market restraints are the high cost of the flow cytometer reagents because of the proprietary nature of most reagents and the lack of transparency in the market. The high profit margin and returns on investment on the flow cytometer reagents has led to the growth of the market with many large firms entering the market.

Led by guest editors Mei Ding, Ph. AstraZeneca, Sweden and Bruce S. Edwards, Ph. University of New Mexico, USA , this special issue presents a range of research papers, application notes and technical notes that reflect recent advances in HTFC methods design, provide new expert insight and perspectives, and highlight areas for improvement to broaden the range of HTFC applications in drug discovery. Examples include descriptions of different software and data analysis workflows; the relative merits of different platforms for assessing biological responses of interest; novel HTFC applications for the development of biologic drugs and novel antibodies; target-agnostic or mechanism-informed phenotypic drug discovery; use of HTFC for single cell analysis; engineering autologous patient T cells to express chimeric antigen receptors CAR-T for use in adoptive cellular therapy of malignancies; and more. Flow cytometry has proven to be a powerful technology, enabling multi-parametric analysis of single cells or particles, and widely used in a broad range of clinical and basic research and applications, including quantification of cell surface and intracellular proteins, DNA analysis, cell proliferation, cell viability, cellular granularity, and cell size. HTFC was made possible by the introduction of novel sample handling and analysis technologies.

Metrics details. Drug-resistant Plasmodium is a frequent global threat in malaria eradication programmes, highlighting the need for new anti-malarial drugs and efficient detection of treatment failure. Plasmodium falciparum culture is essential in drug discovery and resistance surveillance. Microscopy of Giemsa-stained erythrocytes is common for determining anti-malarial effects on the intraerythrocytic development of cultured Plasmodium parasites. Giemsa-based microscopy use is conventional but laborious, and its accuracy depends largely on examiner skill.

What is Flow Cytometry? How does a Flow Cytometer Work?

This increasingly important technique can be applied to all stages of drug development in a range of applications, including cell-line identification, immunophenotyping, and cell-based potency assays. In a regulatory environment, such flexibility can present challenges. Hall explained how scientists can approach FC method development and validation amid rigorous analytical requirements. Flow Cytometry Technology FC provides comprehensive data by analyzing multiple parameters in fluorescently labeled suspensions of cells or particles. The cytometer channels the suspension into a stream of single particles that passes through a flow cell.
