{"product_id":"new-product-400579","title":"PER2\/Period circadian protein 2 Polyclonal Antibody","description":"\u003cp\u003ePER2, a mammalian homologue of the Drosophila period gene, shares a 40% homology with PER1 including the protein dimerization PAS domain. PER2 is a circadian regulator that may act as a transcription factor. It behaves as a negative element in circadian transcriptional loop. PER2 does not appear to bind DNA, suggesting indirect transcriptional inhibition. Expression oscillates with a 24 hour rhythm in the suprachiasmatic nucleus (SCN) and the whole eyes. Oscillations are maintained under constant darkness and are responsive to changes of the light\/dark cycles. There is a 4 hour time delay between PER1 and PER2 oscillations. The expression rhythms appear to originate from retina.\u003c\/p\u003e","brand":"Bioworld","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse,Rat,Dog,Cow,Horse,","offer_id":44092288401632,"sku":"BS65878","price":408.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/products\/bioWORLD-Logo-New_1617713956_abd8420f-4c29-4166-89be-e244e742f981.png?v=1689722656","url":"https:\/\/rndmate.com\/products\/new-product-400579","provider":"알앤디메이트","version":"1.0","type":"link"}
