FLT3 Cell Panel Screening Service

FLT3 and FLT3-Targeted Therapy

FLT3 is a receptor tyrosine kinase that plays a pivotal role in hematopoiesis, particularly in the development and survival of hematopoietic stem and progenitor cells. Mutations in FLT3, such as the internal tandem duplication (ITD) and point mutations in the tyrosine kinase domain (TKD), occur in approximately 30% of AML cases. These mutations lead to constitutive activation of FLT3, promoting uncontrolled cell proliferation and survival. The identification of FLT3 mutations has opened new avenues for targeted therapy in AML, with several small molecule FLT3 inhibitors developed to date.

Despite the initial success of FLT3 inhibitors in clinical trials, challenges such as limited potency and drug resistance have highlighted the need for advanced screening techniques. Next-generation FLT3 inhibitors, capable of overcoming these limitations, are urgently needed to improve patient outcomes. At Creative Biolabs, we have established a robust FLT3 cell panel screening service to address these challenges.

FLT3 Cell Panel Screening Service

Our FLT3 cell panel screening service is a comprehensive approach to evaluate the efficacy and specificity of FLT3-targeted therapies. Utilizing a panel of AML cell lines harboring various FLT3 mutations, we provide detailed insights into drug activity, resistance mechanisms, and potential combination strategies. Our service is designed to support drug discovery efforts and streamline the development of next-generation FLT3 inhibitors.

Services Content

Our cell panel screening involves a series of advanced assays, such as the following items:

• Biochemical kinase assays to assess FLT3 inhibitory activity.
• Proliferation assays using FLT3-ITD and TKD mutant cell lines to evaluate anti-leukemic efficacy.
• Apoptosis assays to determine the impact on cell survival.
• Pharmacokinetic and pharmacodynamic studies to ensure drug stability and sustained activity.

Scientific Backing

Several researches and validation studies has showed the pivotal role of FLT3 mutations in AML pathogenesis and the therapeutic potential of FLT3 inhibitors, antibodies using cell-based panel screening. In this study, the researchers tested the potential role of FLT3 antibodies by conducting experiments based on the leukemia tumor cell line models, elucidating the related mechanisms and therapy response.
