Epi肺泡 tissues are produced on cell culture inserts by differentiating primary alveolar epithelial cells, 肺内皮细胞和成纤维细胞 using a series of proprietary media. Differentiated Epi肺泡 tissues have a squamous epithelium consisting of Type I and Type II alveolar epithelial cells cultured with extracellular matrix producing pulmonary fibroblasts and endothelial cells. The epithelium exhibits functional tight junctions and a robust barrier that remains stable for studies lasting more than 30 days.
A part of the funding for the development of Epi肺泡 was provided by the 善待动物组织国际科学联合会.
The Epi肺泡 3D human tissue model is routinely utilized for a range of applications including safety & 风险评估、炎症 & 纤维化和药物输送. Simple protocols and the evaluation of early cellular endpoints allow scientists to acquire data in days, 而不是几周或几个月.
Use Epi肺泡 to determine relative safety and toxicological potential of inhaled substances.

工具: A standard Epi肺泡 kit (ALV-100-FT-PE12) consists of 24 tissues. (组织“包”包含组织, 培养基250ml, plasticware; contact im体育app for specific kit contents). ALV-100-FT-MAC-PE12, containing THP-1 macrophages is also available.
格式: 12mm Transwell inserts – tissue culture substrate is chemically modified with a pore size of 0.4 μm
很多数字: 每周生产的组织批号都有一个特定的批号. A letter of the alphabet is appended to the end of the lot number to differentiate between individual kits within a given lot of tissues. 所有的组织包在细胞方面都是相同的, Medium, 处理, 培养条件, 等.
装运: ALV-100-FT-PE12 -每周一. ALV-100-FT-MAC-PE12 -每周二.
交付: ALV-100-FT-PE12 – Tuesday morning via FedEx priority service (US). 美国以外地区:周二至周三，视地点而定. ALV-100-FT-MAC-PE12 – Wednesday morning via FedEx priority service (US). 美国以外地区:周三至周四，视地点而定.
保质期: Including time in transit, tissues may be stored at 4°C for up to 3 days prior to use. 但是，不建议延长存储时间. 除了, the best reproducibility will be obtained if tissues are used consistently on the same day.
长度的实验: 组织 cultures can be continued for TWO (2) WEEKS or more with good retention of normal morphology. 面巾纸必须每隔一天用5.0ml维护介质(alv - 100毫米). Cell culture inserts are placed into 6-well hanging culture plates provided (HNG-TOP-6-22).
类型: Normal human alveolar epithelial cells (NHAE); Normal human pulmonary fibroblasts (NHPF), Normal human pulmonary endothelial cells (NHPE) and THP-1 macrophages (ALV-100-FT-MAC-PE12).
抗生素: 庆大霉素30µg / ml
抗真菌剂: 两性霉素b15ng /ml
维护中: alv - 100毫米
目视检查: All tissues are visually inspected and if physical imperfections are noted, 组织被拒绝装运
最终用途测试: Transepithelial electrical resistance (TEER) of each Epi肺泡 lot is measured using an EVOM2 epithelial Volthommeter and Endohm electrode chamber (World Precision Instruments).
不育: All media used throughout the production process is checked for sterility. Maintenance Medium is incubated without antibiotics for 1 week and checked for sterility. The agarose gel from the 24-well plate used for shipping is also incubated for 1 week and checked for any sign of contamination
筛查病原体: All cells are screened and are negative for HIV, hepatitis B and hepatitis C using PCR. However, no known test method can offer complete assurance that the cells are pathogen-free. 因此, these products and all human-derived products should be handled at BSL-2 levels (biosafety level 2) or higher as recommended in the CDC-NIH manual, “微生物和生物医学实验室的生物安全,” 1998.

地段失败的通知: 如果一个组织批次没有通过我们的质量控制或无菌测试, the customer will be notified and the tissues will be replaced without charge when appropriate. 因为我们的QC和无菌测试是在出货后进行的, a notification will be made as soon as possible (Under normal circumstances, TEER故障将在周三下午5点前通知.m.; sterility failures will be notified within 8 days of shipment)
