Anti-KSR1 (phospho S392) Antibody

Rabbit polyclonal antibody from Antibodies.com targeting the phosphorylated serine 392 residue of Kinase Suppressor of Ras 1 (KSR1), a scaffold protein that coordinates RAF, MEK, and ERK assembly within the MAPK cascade. Raised in rabbit and purified as an IgG immunoglobulin, this unconjugated reagent is supplied in a 100 µL vial and is validated for Western blot detection of the S392-phosphorylated form of KSR1 in lysates derived from human, mouse, and rat samples. The phospho-specific epitope allows researchers to probe activation-state changes in KSR1 signaling without cross-reacting with the unphosphorylated protein, supporting studies of receptor tyrosine kinase downstream signaling, Ras-driven pathway regulation, and ERK pathway dynamics in cell biology and oncology research. The polyclonal format provides multiple epitope recognition, which can increase tolerance for minor sample variations during immunoblotting. Storage at -20 °C in working aliquots is recommended to preserve phospho-epitope integrity through limited freeze-thaw cycles.
