{"product_id":"nsj-v4326-20ug","title":"Recombinant Rb1 Antibody \/ Retinoblastoma, 20 ug","description":"\u003cp\u003eRecognizes a 105kDa phosphoprotein, identified as retinoblastoma (Rb) gene product. Its epitope is localized between aa 703-772. It shows no cross reaction with p107 or p130. It specifically stains the nuclei of BT-20 cells and primary human foreskin fibroblast (HFF) cells. It does not stain the Rb-negative BT549 cells. It reacts with the hyperphosphorylated as well as the un (under) phosphorylated form of the Rb protein. Retinoblastoma gene product plays a key role in cell cycle control. It has been identified as a tumor suppressor gene whose loss of its function leads to tumor development. It is widely expressed in a variety of human tissues including breast, esophageal, squamous cell and cervical carcinoma.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug","offer_id":51548637626648,"sku":"V4326-20UG","price":259.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_e8fde6fe-4c8f-48b4-88f4-148b36f4d14b.jpg?v=1768285090","url":"https:\/\/danabiosci.com\/products\/nsj-v4326-20ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
