Cell Culture

The success (or failure) of your experiment starts at the cellular level. From choosing the best cell line, using the right culture conditions and practicing proper handling techniques, following the best practices for cell culture is essential to getting the results you need.

Cell Culture Basics

Cells require proper handling to avoid the risk of contamination or misidentification. Take the time to understand the details of caring for your cells and reduce uncertainty with your downstream experiments.

Reduce Cell Culture Variability

Variability leads to irreproducible results. Set yourself up for success by following these cell culture tips.

Stop Contamination Before It Starts

Imagine discovering your cells aren't what you thought they were. Take care to avoid contamination or misidentification of your cells.

Monolayer Cell Culture

The cell culture model is widely used to observe and measure biological processes. If you want to design a cell-based assay, first you need to understand the basics of cell biology.

Choosing Your Cells

Different cells have different behaviors that may influence your assay results. Here are some factors to consider as you plan your experiments.

Optimizing Your Cell Culture Conditions

Consistent, careful handling of cells is crucial for reliable, repeatable results. Learn how to set yourself up for success in this blog post.

Setting Your Treatment Parameters

Drug dose response curves and time courses paired with multiplexing assays will help you find the "sweet spot" of your experimental system.

3D Cell Culture

Instead of growing cells flat on a plate, how about growing a multicellular 3D spheroid? These microtissues offer a more physiologically accurate environment to benefit your cell health assays.
