For researchers studying G protein–coupled receptors (GPCRs) and other membrane proteins, MembranePro™ expression systems deliver enriched, functional membrane proteins efficiently and reliably.

  • Proteins are displayed on mammalian cell membranes
  • Cellular quality control and mammalian posttranslational processing help produce functional proteins
  • Proteins bud off on lipoparticles and are easily collected from the culture medium
  • Lipoparticles are enriched with expressed receptors

  MembranePro™ Functional Protein Expression Kit NEW Expi293™ MembranePro™ Expression System

The MembranePro™ Functional Kit provides:

  • Easier prep (less labor/hands-on time)
  • Higher receptor density, more homogeneous final product
  • High-density replacement for cell membranes in receptor–ligand binding studies

In addition to the benefits of the MembranePro™ FPE Kit, the Expi293™ MembranePro™ Expression System provides:

  • >20-fold increase in membrane protein yield compared to the adherent culture system*
  • Ease of use—no enzymatic or mechanical dissociation required
  • Scalability—easy scale-up without the need for multiple flasks
