{"product_id":"hek293a-cell-bhc11101242","title":"HEK293A cell","description":"The HEK293A cell line, a derivative of the human embryonic kidney 293 (HEK293) cells, represents a specialized tool in virological and gene therapy research, particularly in the production, amplification, and titration of replication-incompetent adenoviruses. These cells exhibit a flat morphology, which significantly aids in the microscopic examination and titration processes, making it simpler to count and assess viral particles.\nA pivotal feature of the HEK293A cell line is the stable integration of the adenovirus E1 gene into its genome. This integration is critical as it provides the necessary transcriptional machinery for the expression of E1 proteins, specifically E1a and E1b. The presence of these proteins is essential for the replication of adenoviral vectors in the cell. The E1a protein primarily functions to activate transcription of the adenovirus genome, while E1b proteins are involved in viral replication and cell cycle disruption.\nThe utility of HEK293A cells extends beyond merely supporting viral replication. These cells facilitate the efficient production of high titer, high-quality viral preparations essential for both basic research and therapeutic applications. The cell line's robust replication capacity and ease of handling enable researchers to screen and develop adenoviral constructs with unprecedented precision and efficiency.\nIn summary, the HEK293A cell line is an indispensable resource in the field of virology and gene therapy. Its ability to stably express E1 proteins and support adenoviral replication makes it a valuable tool for researchers looking to produce and manipulate adenoviral vectors. The cell line's characteristics allow for the efficient generation of viral vectors, crucial for advancing research and potential therapeutic interventions.\n\u003cp style=\"display:none\"\u003eSKU:BHC11101242\u003c\/p\u003e","brand":"Cytion","offers":[{"title":"1 cryovial","offer_id":52950205596013,"sku":"305070","price":395.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/293A_20P1_2020x01_2002062023_1920x1920_fd241ae7-d7ec-484f-9bd6-34b801e74b4c.jpg?v=1769069042","url":"https:\/\/www.ebiohippo.com\/products\/hek293a-cell-bhc11101242","provider":"BioHippo","version":"1.0","type":"link"}
