Anti-MEF2D (phospho-S444) Antibody

Raised in rabbit as a polyclonal reagent, this phospho-specific antibody recognizes MEF2D only when serine 444 is phosphorylated, an epitope positioned within the C-terminal transactivation domain used to monitor post-translational regulation of MEF2-dependent transcription. The unconjugated preparation is supplied by Antibodies.com at 1 mg/ml in phosphate buffered saline containing 0.05% sodium azide, pH approximately 7.2, in a 100 µl vial. Verified reactivity with human, mouse, and rat samples supports western blot and immunohistochemistry workflows in muscle differentiation, cardiac, and neuronal studies, where S444 phosphorylation serves as a read-out of upstream kinase activity controlling MEF2D function.
