Anti-ETAA1 Antibody

Raised in rabbit as a polyclonal reagent, this unconjugated primary antibody recognizes Ewing tumor-associated antigen 1 (ETAA1), a DNA replication stress-response factor that activates ATR kinase at RPA-coated single-stranded DNA and contributes to genome stability during S-phase. Available from Antibodies.com, the reagent is supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, packaged as a 100 µl vial, and validated for Western blot (WB) detection of endogenous ETAA1 in human and rat samples. The polyclonal format offers recognition of multiple epitopes on the target, useful for monitoring ATR pathway activation, replication fork stress responses, and ETAA1 phosphorylation events across cell-based and biochemical workflows. For routine handling, store the vial at -20°C, prepare working aliquots to limit freeze-thaw cycles, protect from light, and dilute into standard blocking buffer for immunoblotting at the concentration appropriate to your protocol.
