We made CHO transfection easy. Introducing CHO4Tx®, a unique CHO transfection system developed by ExcellGene in Switzerland, manufactured by Magellan Biologics in Portugal.
Now you can produce your antibody in three simple steps.No transfection reagent required One simple, reliable protocol From milliliter to liter scale No waiting for DNA complex formation Works with CHO Stable or transient transfections
How does it work?By reducing the attention required to key steps of a conventional transfection protocol, we’ve taken out the guesswork for you to obtain your antibody reliably, in high throughput manner and desired yield. Simply prepare your cells in the transfection medium, add your DNA, incubate for three hours, and add our production medium to get your protein within a week.
Your antibody in three simple steps
1. Prepare cells
2. Add DNA
3. Produce protein
What’s in the kit?
One simple, reliable protocol
Take the guesswork out of transfection.
