Per2 Antibody (19-J6) is a mouse monoclonal IgG2b antibody that detects Per2 in human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). Per2 (19-J6) antibody plays a crucial role in studying the regulation of circadian rhythms, as Per2 acts as a key component of the molecular clock that governs physiological processes such as sleep-wake cycles and hormonal fluctuations. Located primarily in the suprachiasmatic nucleus (SCN) of the brain, Per2 is essential for maintaining the timing of these biological rhythms, and Per2 expression is tightly regulated by light exposure. Notably, Per2 interacts with other period proteins, including Per1 and Per3, to form a feedback loop that stabilizes circadian oscillations. Disruptions in Per2 function can lead to altered circadian rhythms, which have been linked to various health issues, including sleep disorders and metabolic syndromes. anti-Per2 antibody (19-J6) serves as an invaluable tool for researchers studying the intricate mechanisms of circadian biology and its implications for human health.

Can sc-101105: Per2 (19-J6) monoclonal antibody be used to stain formalin-fixed, paraffin-embedded (FFPE) tissue sections?

Asked by: jenniferc
Thank you for your question. Yes, sc-101105: Per2 (19-J6) is recommended for use in IHC with paraffin-embedded sections. We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
