Membrane Protein Antibody Specificity ProfilingOnline Inquiry
Typical antibody quality control (QC) involves evidence of binding to the intended target, while potential antibody cross-reactivity is often overlooked or marginalized. Poor validation of antibodies due to unrecognized cross-reactivity, or even inability to react completely with the intended target, has led to misleading or erroneous conclusions for analyses using them as reagents. Nowadays, it is recognized that rigorous specificity analysis is critical for successful antibody-based drug discovery and development (e.g. CAR-T).
Membrane protein-based antibody specificity profiling
About a quarter of the human proteome encodes membrane proteins, which play critical roles in countless cellular functions and are essential in many disease processes. Over the past 20 years, new technologies and methods have greatly advanced the discovery and development of membrane protein-based drugs, including small molecule drugs and monoclonal antibody (mAb) therapeutics. To efficiently discover therapeutically relevant antibodies, there is a growing shift towards functional screening strategies that allow the rapid isolation of molecules with desired cellular effects. Membrane protein microarray, inspired by the previously developed DNA microarray technology, assembles a large number of membrane proteins to meet the needs of different applications, such as small molecule drug discovery, vaccine development, and antibody development (antibody target identification and antibody specificity profiling). This technology can be used to validate the specificity of antibodies to known membrane protein targets. In addition, membrane protein microarrays can provide additional information by identifying binding to other membrane proteins, thus facilitating the final lead selection in the project to avoid off-target binding.
