EmCD CHO-S 203 Medium

EmCD CHO-S 203 Medium is tailored for specific CHO cells, prominently ExpiCHO-S and CHO-K1. This formula, defined by its precise chemical composition, lacks proteins, serum, and components of animal origin, standing as a beacon of quality, reliability, and efficiency.

Key Features

• Chemically Defined Composition: Our medium boasts a clear chemical composition, free from proteins, serum, and any animal-derived elements. This ensures unparalleled uniformity.

• Optimized for ExpiCHO-S and CHO-K1 Cells: Specifically designed for high-density transient transfection in ExpiCHO-S and CHO-K1 cells, our medium maximizes the expression of target proteins.

• Reduced Doubling Time: With a doubling time of approximately 17 hours, this medium optimizes the cell growth rate.

• Effortless Transition: Transition smoothly from other media, minimizing acclimatization time.

• Enhanced Transfection: Simplifies the transfection process by being suitable for dilution during transfection reagent preparation.

• Synergized with EmACF CHO 203 Supplement: When used in conjunction with EmACF CHO 203 Supplement, it significantly elevates cell density, maintains high cell viability, and augments antibody and recombinant protein production.

• GMP Compliance and Superior Quality: Crafted to meet GMP standards, EmCD CHO-S 203 Medium delivers unmatched consistency and controllability for your bioprocess necessities.

Considering to Use EmCD CHO-S 203 Medium

• When transitioning between different cell culture media and aiming to minimize acclimatization periods.

• When aiming for high-density transient transfection in ExpiCHO-S and CHO-K1 cells.

• When the goal is to maximize protein expression and ensure superior cell growth rates.
