8.What are the storage conditions for in Dmem cell culture medium?

A proper storage conditions are necessary for the stability and integrity of medium as it is used for cell growth. For a successful culture, a best storing is required as it acts as a life line. A slight lapse in storing can compromise the culture outcomes. Are you excited to know? Let’s dive into this.

Temperature

Temperature-Picture courtesy: studyfinds.com

Dmem cell culture medium requires an optimum temperature of two to eight centigrade. If temperature go beyond this, components such as vitamins, amino acids and others may degrade and medium lose its integrity and stability. This can compromise the effectiveness of media.

Freezing

Freezing -picture courtesy: biolabscientific.com

Freezing this culture medium is not suitable to it.  This is because some of the components in Dmem cell culture medium becomes inactive and precipitate. When use for cell culture, these components, then, don’t dissolve properly. So, it has negative effect.

Light

Medium deteriorated when exposed to light and its impacts show during cell growth. Some of the components such as vitamins and amino acids are sensitive to the light. When ultraviolet light falls on medium, these sensitive components break down that lose its quality of supporting healthy cell growth. So, store in amber bottles.

Shelf life

Shelf life

Typically, the shelf life of unopened Dmem cell culture medium is twelve months. But when opened, its shelf life decrease. It can be three to four weeks. Sometimes, it is said that its shelf life would extend when keep it in refrigerator, there is nothing like this in this case.

9.What is the difference between Dmem cell culture medium and Mem cell culture medium?

Dmem cell culture medium and Mem cell culture medium

There are different culture mediums is used to culture mammalian cells. But, choosing the best is on the top priority. Dmem cell and MEM culture medium are the two formulations media that are different characteristically and used for different cel types. Both can have different outcomes. Following below are the points that will make you learn the difference between the two.

Difference	Dmem cell culture medium	Mem cell culture medium
Glucose concentration	This kind of medium is available in both low level and high level of glucose. So, researcher can use any of its form depend on the type of cell that require energy.	While this medium is available in low level of glucose only. Thus, researcher does not have a choice to use this medium for energy intensive cells.
Nutrients concentration	Dmem medium contains more nutrients or amino acid that is favorable to support culture of high metabolism and for the culture that is for long duration.	Mem medium has a normal level of nutrients and I used for cell type cultures that are simple in nutritional needs.
Cell type	It is ideal for the cells that are fast growing and needs a high metabolic environment such as fibroblast, stem cells etc.	This is used for sensitive cells such as primary cells that do not high notorious environment and demands minimal conditions to thrive in such as HeLa cell etc.
Adaptability	This medium can be modified by adding supplements.	While Mem medium is rigid. You can do less modifications in it.
Buffer capacity	It contains high level of buffer agent such as sodium bicarbonate so, it has good buffering capacity.	It also contains sodium bicarbonate as buffer agent but in normal level. Hence, it also works well but offer less flexibility.

10.What precautions should you consider when handling a Dmem cell culture medium?

When handling a Dmem cell culture medium, different points should be keeping in. following below are the precautions you should consider.

Avoid repeated cooling and heating      

Avoid repeated cooling and heating

The first thing to keep in mind is don’t put out the entire medium when using. The medium will get unsterile and will catch microbial growth when open repeatedly for repeated change in temperature.

Store at correct temperature

Store at correct temperature

Store the medium by correct temperature usually under two to eight centigrade. Try to avoid freezing the medium as freezing it can degrade it and precipitate its sensitive components and it can lose its effectiveness.

Use sterile tools

11.Do you know the ways to troubleshoot the poor cell growth in Dmem cell culture medium?

Behind every problem, there are root causes. A poor cell growth in Dmem cell culture medium is due to several factors. A troubleshooting involves checking the medium and restore a healthy cell growth. Followings are the ways to trouble the poor cell growth in Dmem cell culture medium.

Evaluate Supplement

In Dmem cell culture medium, additional supplements are added to be modified for any cel line. Supplements like fetal bovine serum are sensitive to heat and affect the growth of cell culture. For this, use or add a freshly serum. Don’t add over and under concentration of other supplements too.

Check medium quality

Another way to trouble shoots the poor cell growth is to check whether this medium is in good condition or not. What does a good condition mean? It means to check whether the medium is contaminated free or not, if any change in color happen from red to any other, then it means a PH imbalance.

Check cell heath line

Check the cell line health. High passage cell line results in genetic mutation. There can be mycoplasma contamination that causes the poor metabolic activity. Thus, use a fresh and health cell lines and also conduct tests for mycoplasma contamination.

Assess sterility

The equipment you use for handling a Dmem cell culture medium are very important. A slight in sterility can compromise the whole media and affect the cell growth. If medium shows any sign of microbial growth, discard the media. Use a hygiene incubator, contains and other usable equipments.

Confirm media compatibility

Different cells require different cell culture medium for their growth. Before use, check whether the cell line you are using is compatible with Dmem medium. Some are compatible but require different glucose level. Make sure the exact glucose level, high or low, for the cell line.
