We are happy to announce a new application note written by our very own, Research Scientist, Dr. Zachary Imam.

Cell culture media is a complex fluid composed of nutrients required for cells to grow, proliferate, and differentiate. Media is specifically designed to maintain the ideal nutrients, hormones, pH, and osmotic environment necessary for cell growth. Different types of cells prefer different types of media. For example, many mammalians cell lines are grown and maintained using Ham’s or F12 media, while insect cells are typically grown in Grace’s medium. Furthermore, some types of cells are best grown in mixtures of different media formulations such as combination medias comprised of DMEM and F12. Characterizing the differences between formulations is vital for developing new products and for maintaining quality control for existing product lines.

In this application note, we investigated the viscosity of F12 media formulations. We showed that filtering the media with a 0.2 μm filter does not impact media viscosity, there is not a difference in viscosity between purchased and homemade DMEM/F12 media, and the viscosity of DMEM/F12 is equivalent to the
DMEM component in the formulation.

The goal of this application note is to display viscosity data for different formulations of F12 media were collected on VROC® initium. There was not a significant difference in viscosity observed between filtered and unfiltered F12 media. There was also no difference in viscosity found between the commercial and homemade DMEM/F12 combination media. However, it appears that the DMEM viscosity is larger than the F12 but comparable to the DMEM-F12 combination media.
