Protein & Antibody Production

CHO Cell

Identify and characterize top candidates with high-titer transient protein and antibody production. MaxCyte® electroporation technology offers production system flexibility, performance and scalability supporting R&D, toxicology studies and beyond. When the time is right to invest in stable cell line development, MaxCyte can get you there faster too.

Experience the advantage of working with the ExPERTs

  • Obtain milligram to grams of protein within days from a single transfection.
  • MaxCyte’s unique combination of technology, scientific support and regulatory expertise will help you reach your goals faster.
  • Use your manufacturing cell line from the start, eliminating the cost and time associated with revalidation and the risk of product failure when switching.

Use the right cells, right from the start

The MaxCyte ExPERT platform gives you the freedom to use the cell type that makes the most sense for your project.

Whatever type of cell you use, MaxCyte electroporation technology delivers virtually any molecule with high efficiency and cell viability for high titer recombinant protein production.

MaxCyte’s ExPERT platform enables reproducible transfection of many cell types commonly used for protein production including:

  • CHO and CHO-derivatives
  • HEK
  • Vero
  • NS0
  • Insect

High titer transient antibody expression in days, not months

Supporting high titer antibody expression at any scale, MaxCyte electroporation accelerates your antibody production process.

High protein yields from transiently transfected cells enable you to do more with transiently expressed material, saving the time and resources required for stable cell line development.


Electroporation of CHO-K1SV cells yields antibody titers in excess of 1g/L in under two weeks.


High antibody titers achieved with MaxCyte electroporation in ExpiCHO™ can be increased using alternative culture media.

Flexibility to optimize culture conditions to maximize transient titres

Numerous variables can affect transgene expression in both stable and transient production, including cell type, culture density and media/feed strategy. Reproducible, efficient transfection with MaxCyte instruments and consumables enables you to rapidly identify the conditions for optimal transient yields in your system.

High cell viability after electroporation enables condensed timelines for stable cell line development

Stable cell line development can be costly and time-consuming. When you’ve identified top leads, you want to obtain high-yielding clones and establish a Master Cell Bank as quickly as possible. MaxCyte electroporation couples high-efficiency transfection with high cell viability, which means cells recover quicker and selection can start sooner, condensing timelines.


High cell viability after MaxCyte electroporation enables selection to start within two days for rapid stable cell line development.

Supercharge your antibody production process with MaxCyte.

Whether expressing antibodies for use as diagnostics or biotherapeutics, speed is
critical. MaxCyte electroporation technology enables the transient production
of grams of antibodies, bispecifics or other antibody types in days to weeks, from
one electroporation step, in your chosen biomanufacturing cell line.
