Common Mistakes to Avoid When Using L-15 Medium

The L-15 medium is a preferred medium among scientists. This is due to the fact that this media supports the corresponding growth in the absence of a CO2 incubator. However, most professionals in the laboratory make some mistakes that affect the efficiency of their cultures. Are you using L-15 the proper way? Below, we discuss some causes of errors that should be avoided in order to help you improve your experiments.

Are You Storing L-15 Medium Correctly?

One most common mistakes for the L-15 medium is not storing properly. Unlike other culture media that use layers of CO₂ for pH control, Leibovitz’s 15 medium contains special buffering agents that keep the pH in line in the absence of CO₂. Nevertheless, improper stands impact the quality of culture.

Are you storing your Leibovitz 15 medium at room temperature for long periods? You could be damaging the medium. It should always be refrigerated at 2-8º C to maintain freshness. Repeated freeze-thaw cycles should also be avoided because nutrients could be broken down to the extent that the medium is not optimal in supporting cell growth.

Are You Adding the Right Supplements?

Researchers often assume that L-15 media can be used straight out of the bottle, but this is not always true. Depending on your cell line, you might need to add supplements like serum, amino acids, or growth factors.

Have you checked if your cells require additional nutrients? Using too little or too much of a supplement can harm cell growth. Always follow recommended guidelines for supplementation and adjust the formula based on the needs of your experiment.

Are You Monitoring pH Levels Properly?

One of the largest benefits of Leibovitz 15 is its suitability to maintain pH without CO2. However, this does not imply that the pH will remain stable for a long period. There may be fluctuation in pH due to external factors such as cell metabolism, extensive exposure to light, and prolonged culture times.

Other than these, have you seen any color changes in your medium? A normal L-15 medium must have a slight reddish-orange tint. When it becomes yellow or purple, chances are high of variations in pH. Regular checks and timely replacements should be done to avoid possible deviations that could affect your experiment.

Are You Using L-15 Medium for the Right Applications?

All cell types do not thrive in L-15 medium, and using it for the wrong application could give poor results. Have you confirmed that your cells are compatible with this medium?

L-15 is ideal for certain primary cells and established cell lines, particularly in virology, oncology, and transport studies. If you are unsure whether L-15 media is the right choice for your research, check the scientific literature or consult an expert before proceeding.
