Hepg2 là gì
HB-8065™ Hep G2 [HEPG2] is a cell line exhibiting epithelial-like morphology that was isolated from a hepatocellular carcinoma of a 15-year-old, White, male youth with liver cancer. The cell line was deposited by the Wistar Institute and is a suitable transfection host. Expression markers include insulin; insulin-like growth factor II (IGF II). Product category Human cells OrganismHomo sapiens, human Morphology epithelial-like Tissue Liver DiseaseCarcinoma; Hepatocellular Applications3D cell culture Cancer research High-throughput screening Toxicology Product format Frozen Storage conditionsVapor phase of liquid nitrogen DocumentationBSL 1ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies. ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen. Required ProductsThese products are vital for the proper use of this item and have been confirmed as effective in supporting functionality. If you use alternative products, the quality and effectiveness of the item may be affected. GeneralSpecific applications These cells are suitable as a transfection host CharacteristicsGrowth properties Adherent Derivation HepG2 was derived from a liver hepatocellular carcinoma of a 15 year old Caucasian male. Age 15 years Ethnicity White Gender Male Karyotype modal number = 55 (range = 50 to 60); has a rearranged chromosome 1 Tumorigenic No; No, in immunosuppressed mice Yes, in semisolid medium Genes expressed alpha-fetoprotein (AFP, alpha fetoprotein); albumin; alpha2 macroglobulin (alpha-2-macroglobulin); alpha1 antitrypsin (alpha-1-antitrypsin); transferrin; alpha1 antichymotrypsin (alpha-1-antichymotrypsin); haptoglobin; ceruloplasmin; plasminogen, complement (C4); C3 activator; fibrinogen; alpha1 acid glycoprotein (alpha-1 acid glycoprotein); alpha2 HS glycoprotein (alpha-2-HS-glycoprotein); beta lipoprotein (beta-lipoprotein); retinol binding protein (retinol-binding protein) Expression markers Insulin; insulin-like growth factor II (IGF II) CommentsThe cells express 3-hydroxy-3-methylglutaryl-CoA reductase and hepatic triglyceride lipase activities. The cells demonstrate decreased expression of apoA-I mRNA and increased expression of catalase mRNA in response to gramoxone (oxidative stress). There is no evidence of a Hepatitis B virus genome in this cell line. In addition to the hepatocellular carcinoma or hepatoma cell line based on the original publication (PubMed: 6248960), HepG2 is also referred as hepatoblastoma cell line (PubMed: 19751877). Technical informationATCC Technical Services does not have technical information on patent deposits that are not produced or characterized by ATCC. Additional information can be found in the corresponding patent available from the patent holder or with the U.S. and/or international patent office. Handling informationUnpacking and storage instructions
37°C Atmosphere95% Air, 5% CO2 Handling procedureTo insure the highest level of viability, thaw the vial and initiate the culture as soon as possible upon receipt. If upon arrival, continued storage of the frozen culture is necessary, it should be stored in liquid nitrogen vapor phase and not at -70°C. Storage at -70°C will result in loss of viability.
