Tau protein, encoded by the MAPT gene, serves as a critical regulator of microtubule stability in neurons and has become one of the most intensively studied targets in neurodegenerative disease research. Phosphorylation at serine 214 represents a particularly significant modification, as this site lies within the proline-rich region of tau and contributes to the pathological hyperphosphorylation patterns observed in Alzheimer's disease and related tauopathies. Detecting this specific phosphorylation event enables researchers to distinguish between normal tau function and the aberrant modifications associated with neurofibrillary tangle formation.
This recombinant monoclonal antibody, clone 31B12, offers the reproducibility essential for longitudinal studies and multi-site collaborations investigating tau pathology. Because the antibody sequence is defined and production occurs in controlled recombinant systems, researchers can expect consistent performance across experiments and lot numbers, eliminating a common source of variability in phospho-specific antibody work. The rabbit host and IgG isotype provide strong signal amplification potential while maintaining specificity for the phosphorylated epitope.
Validation in human brain tissue demonstrates this antibody's utility for examining tau phosphorylation in its most clinically relevant context. Immunohistochemistry performed on paraffin-embedded human brain sections using a Leica Bond system with citrate buffer antigen retrieval produced clear staining at 1:100 dilution, with a recommended working range of 1:50 to 1:200 allowing optimization for different tissue preparations and detection systems.
For researchers investigating tau biology, Alzheimer's disease mechanisms, or signal transduction pathways regulating neuronal cytoskeletal dynamics, this phospho-MAPT antibody provides a reliable tool for tracking disease-relevant modifications in human tissue samples.
