Anti-ERK 1 Antibody

Manufactured by Antibodies.com as a primary antibody for MAPK signaling research, this rabbit polyclonal reagent specifically detects endogenous levels of ERK 1 (MAPK3) and is raised against a synthesized peptide derived from the internal region of human ERK 1. The antibody is affinity-purified from rabbit antiserum by epitope-specific affinity chromatography and supplied as an unconjugated liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide, at a working concentration of 1 mg/mL. It is validated for use in ELISA, Western blot (WB) and immunocytochemistry/immunofluorescence (ICC/IF), and it cross-reacts with Human, Mouse and Rat samples, making it suitable for comparative studies across mammalian model systems. The polyclonal format provides broad epitope coverage for reliable detection of the endogenous target, and the unconjugated formulation allows researchers to pair the reagent with their preferred secondary antibody or custom labeling strategy. The product is offered at the 50 µl pack size and is intended for research use only; it is not validated for diagnostic or therapeutic applications. For optimal stability, the manufacturer recommends storing the antibody according to standard cold-chain practice and avoiding repeated freeze/thaw cycles, which helps preserve both binding activity and the protein-stabilizing BSA component in the buffer.
