Anti-PER3 Antibody

Offered by Antibodies.com as a primary antibody for circadian rhythm research, this rabbit polyclonal reagent targets the PER3 (Period Circadian Protein Homolog 3) protein and is validated for Western Blotting and Immunohistochemistry. The antibody is supplied as a 50 µl liquid aliquot in unconjugated form, raised in rabbit and purified as a polyclonal IgG preparation, with documented reactivity against human, mouse and rat samples. It is recommended for studies of the mammalian circadian clock, where PER3 functions alongside PER1 and PER2 in the negative feedback loop that drives 24-hour rhythmicity. Standard short-term storage at 2–8 °C is advised, with longer-term aliquoting and freezing at –20 °C or below to preserve activity across repeated experiments. Researchers should perform appropriate positive and negative tissue controls, and titrate the antibody for IHC and WB depending on the species and sample preparation.
