Opti-MEM™ Reduced-Serum Medium is an improved Minimal Essential Medium (MEM) that allows for a reduction of Fetal Bovine Serum supplementation by at least 50% with no change to growth rate or morphology. Opti-MEM™ is also recommended for use with cationic lipid transfection reagents, such as Lipofectamine™ reagent. Opti-MEM™ can be used with a variety of suspension and adherent mammalian cells, including Sp2, AE-1, CHO, BHK-21, HEK, and primary fibroblasts. We offer a variety of Gibco™ Opti-MEM™ modifications for a range of cell culture applications.


This Opti-MEM™ is modified as follows:
With
• GlutaMAX™
• Phenol Red


The complete formulation is confidential. For more information, please contact Technical Services.

Gibco™ Opti-MEM™ is a unique media that contains insulin, transferrin, hypoxanthine, thymidine, and trace elements. These additional components allow for a reduction in serum supplementation by at least 50%. Gibco™ Opti-MEM™ with GlutaMAX™ supplement minimizes toxic ammonia build-up and improves cell viability and growth in an easy-to-use format.

Gibco™ Opti-MEM™ uses a sodium bicarbonate buffer system (2.4 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.

Frequently asked questions (FAQs)

Is there any other difference between Opti-MEM I Reduced Serum Medium and Opti-MEM I Reduced Serum Medium, no phenol red besides the presence/absence of phenol red?

The formulation of Opti-MEM I Reduced Serum Medium and that of Opti-MEM I Reduced Serum Medium, no phenol red is the same except for the presence of phenol red in the former medium.

Where can I find the osmolality for my lot of Opti-MEM I Reduced Serum Medium?

We do provide osmolality information on the certificate of analysis. All lots of Opti-MEM I Reduced Serum Medium will meet the osmolality specification of ≥280 to ≤320 mOsm/kg.

Can I aliquot and freeze Opti-MEM I Reduced Serum Medium to conserve it longer? If so, for how long can it be stored?

Sorry, we don't have data to show that frozen Opti-MEM I Reduced Serum Medium has a longer shelf life. Actually, we recommend storing this medium at 2-8 degrees C in the dark. We do not recommend freezing the medium because it may precipitate.

I noticed that Opti-MEM I Reduced Serum Medium does not contain any serum. Why do you then refer to it as "Reduced Serum Medium"?

Opti-MEM I Reduced Serum Medium is a serum-free medium. The reason why it is called “reduced-serum medium” is because you only need to supplement this medium with 1-5% FBS instead of the standard 10% FBS.

Opti-MEM I Reduced Serum Medium can be used as is (without serum) for transfection of cells. However, for long-term cell culture, you need to add serum to the medium to keep cells healthy.

Will depletion, absence, or breakdown of essential growth-promoting components such as glutamine or growth factors reduce the growth rate of my culture?

Yes. If you suspect that this is the case, remove the medium and add fresh medium. Alternatively, you can supplement medium with growth-promoting components. It is also possible to substitute GlutaMax I or II for glutamine in the medium to prevent glutamine exhaustion.

Abstract
A solution for highly efficient electroporation of primary cytotoxic T lymphocytes.
Authors:Alawar N,Schirra C,Hohmann M,Becherer U
Journal:BMC biotechnology
PubMed ID:38532411
BACKGROUND: Cytotoxic T lymphocytes (CTLs) are central players in the adaptive immune response. Their functional characterization and clinical research depend on efficient and reliable transfection. Although various methods have been utilized, electroporation remains the preferred technique for transient gene over-expression. However, the efficiency of electroporation is reduced for human and ... More
