Molecular profiling involves the analysis of a biological sample, such as DNA, RNA, or proteins, to provide detailed information about the molecular characteristics of an organism or cell. This can include identifying genetic mutations, gene expression patterns, and protein levels, among other molecular features. Molecular profiling is commonly used in research to study disease mechanisms, identify potential drug targets, and personalize treatment approaches for patients. This area of research has led to significant advances in understanding the molecular basis of diseases and has the potential to revolutionize healthcare by enabling precision medicine approaches tailored to individual patients.
