Espresso (formerly MaxPak) Competent Mammalian Cells are specially prepared to offer significantly increased protein expression yield for a given cell culture vessel. Because MaxPAK Competent Cells can be plated at a much higher cell density (4x) than is possible for traditional passaged cells, up to 4 fold protein yield enhancement can be achieved. This makes MaxPAK Cells ideal for both protein production and high-throughput testing of expression constructs. Although Espresso Cells appear smaller and rounder when compared to regular cells, they are not genetically modified. They can be propagated and passaged just like regular cells and exhibit the same morphology as their passaged counterparts after only 24 hours of incubation.

Advantages vs Standard (De-Caf) Cells:

• Simply thaw cells, plate and transfect
• No cell passaging–all it needs is a 3-hour incubation after thawing
• Revolutionary cell culture technology* for achieving 4X more cell density
• Start and finish your experiment in hours instead of days
• Available cell lines: HeLa, HEK 293, CHO-K1

Our New FluoGreen Tracer can be used to visualize primary cell nuclei and cystoplasm!
