Transwell permeable supports are convenient and easy-to-use devices for studies of both anchorage-dependent and anchorage-independent cells. These inserts provide independent access to both sides of a monolayer, thus giving researchers a versatile tool to study transport and other metabolic activities in vitro. Below you will find guidelines for use for Transwell permeable supports, as well as other helpful tips and techniques. Transwell permeable supports are available in three membrane materials: polycarbonate, polyester PET , and collagen-coated polytetrafluoroethylene PTFE. Polycarbonate Transwell inserts feature thin, translucent membranes available in four pore sizes ranging from 0.

Use and Design. As an industry leader and essential tool in the lab for over 25 years, Transwell permeable supports are backed by extensive citations, protocols, and scientific support—all to help create a cell culture that more closely mimics an in vivo environment. Permeable supports enable life science research and discovery for the study of both anchorage-dependent and independent cell lines. Permeable supports come ready to use, pre-packaged in standard multiple well plates. Individual inserts are also available. Include them in your research, and get ready to transform your scientific concepts into life-changing discoveries. The unique self-centering hanging design of Transwell inserts prevents media from wicking between insert and plate well. It also keeps the membrane just off the well bottom, preventing co-cultured cell monolayers in the lower compartment from being damaged when the insert is moved. To get the most out of your permeable support inserts, take a look at these top 25 tips and techniques submitted to us by scientists just like you. Transwell-COL collagen-coated inserts have a transparent when wet collagen-treated PTFE membrane that promotes cell attachment and spreading, while allowing cells to be visualized during culture. The coating process covers each fibril of the matrix, thereby retaining the porosity of the membrane. Individual inserts are used with 6, 12, and 24 multiple well plates. A large, single-well format is also available in a mm dish. To ensure success, we recommend that researchers validate their methods independent from our reported values.

Transwell migration and invasion assays are used to determine if cells can move through a porous membrane migration assay or both the membrane and an extracellular matrix invasion assay. Invasiveness is a characteristic feature of more advanced transformed cells, as it is necessary for metastasis. A plate of confluent cells in a monolayer. Therefore, the usual mock treatment controls apply. A chemoattractant is placed in the lower chamber of a cell culture plate. The cells are placed on top of a porous transwell membrane alone for the mobility assay or one covered with extracellular matrix for the invasion assay.

Add to basket. Transwell inserts have three openings for standard pipet tips to allow samples to be added or removed from the lower compartment. The polycarbonate or polyester membrane with the fixed and stained cells attached may be removed from the Transwell insert by carefully cutting around the membrane edges with a scalpel. See Note 7.
