Polycarbonate 3.0 μm and 5.0 μm membranes and 8.0 μm pore polyester (PET) membrane are available for the HTS Transwell -96 Permeable Support product line. These pore sizes allow chemotaxis and cell invasion assays in a high-throughput format, enabling assays to be conducted in smaller volumes and more samples to be tested in a single plate. HTS Transwell -96 Cell Migration Products provide a large cell growth surface area, standard bar codes and an improved gripping surface. The new products are both automation and manual friendly, operating with easy-to-use media and cell access ports that facilitate efficient media sampling. The Black Receiver Plate used for fluorescent read-out facilitates higher sensitivity by lowering the background, helping scientists be more precise in their experiments.
