Your ELISA confirms the therapeutic enzyme is present. Your Western blot shows a band at the correct molecular weight. But here’s the critical question: is the enzyme actually functional? For mRNA-based enzyme replacement therapies targeting rare metabolic diseases, producing protein mass isn’t enough. Many enzymes require specific phosphorylation patterns for catalytic activity. Without direct measurement […]
The discovery and development of natural products continues to represent a cornerstone of pharmaceutical innovation, yet traditional bioactivity-guided fractionation approaches increasingly yield diminishing returns as researchers encounter the rediscovery problem. Modern biotechnology and pharmaceutical companies are shifting toward sophisticated omics-based strategies that leverage metabolomics and proteomics services from specialized contract research organizations (CROs) to explore […]
Why Accurate SDMA and ADMA Measurement Is Essential for PRMT5 Inhibitors The protein arginine methyltransferase (PRMT) field has a measurement problem that’s quietly undermining drug development programs across the industry. While symmetric dimethylarginine (SDMA) and asymmetric dimethylarginine (ADMA) are both methylated arginine metabolites, their biological roles, and responses to PRMT inhibition, are fundamentally different. Yet […]
Phenotypic Screening and Target Deconvolution for Molecular Glue Discovery Molecular glue degraders represent a unique class of therapeutic compounds that modify E3 ligase substrate specificity to induce targeted protein degradation. Unlike PROTACs, which require known binders for both target proteins and E3 ligases, molecular glues are often discovered through phenotypic screening approaches where the mechanism […]
The Assumption That Derails Programs The promise of mRNA therapeutics is elegant: deliver genetic instructions, let cells produce therapeutic proteins, and bypass traditional drug manufacturing. But there’s a critical gap between mRNA design and therapeutic outcome. Your construct may be producing proteins you never intended and your standard assays might miss them entirely. Most mRNA […]
Why Quality Systems Matter More Than You Think When you’re deeply immersed in assay development or screening potential biomarkers, regulatory compliance might understandably feel like an afterthought, given that your primary focus necessarily gravitates toward the science itself – optimizing protocols, systematically troubleshooting technical issues, and generating meaningful data that advances your understanding. But here’s […]
