ABOUT
Antimicrobial agent for primary cells
Primocin® is designed to offer complete protection of primary cells from microbial contamination. Primocin® is a broad-spectrum antibiotic formulation that is gentle on your cells but lethal to the microbes. There are a number of common sources of microbial contamination especially in the isolation of primary cells from both animal and human tissue, including commensal flora and/or subclinical infections.
Key Features:
- Active against bacteria, mycoplasma, and fungi
- A common addition to various standardized primary cell culture protocols
- Used throughout culturing process (e.g. culture media, wash solutions, and biopsy storage media)
- Highly cited in the literature
Primocin® is composed of four compounds, of which three, act directly on Gram-positive bacteria, Gram-negative bacteria, and mycoplasmas. The primary mode of action for these compounds is to block microbial DNA and protein synthesis. The fourth compound in Primocin® eradicates fungi, including yeasts, by directly targeting processes at the fungal membrane.
Primocin® is successfully used in many types of primary cell cultures (see citations) including:
- Differentiated mouse- and human-derived cells such as astrocytes and immune cells (e.g. natural killer cells)
- Stem cells such as mouse- and human-derived embryonic and pluripotent stem cells
- 3D cellular models (i.e. organoid and spheroids) such as colon epithelial and carcinoma organoids
Primocin® is made in-house at InvivoGen and is of the highest quality with rigorous quality control performed to ensure the absence of lot-to-lot variation.

Use of Primocin® in primary cell cultures
Primocin® is frequently cited in the literature for use in the protection of a number of different primary cell cultures. This includes (but is not limited to):
- Numerous human and murine primary cell cultures, including fibroblasts [1], glial cells [2], astrocytes [3], and immune cells (e.g. NK cells) [4].
- Culturing and reprogramming of human and murine embryonic cells [5] and pluripotent stem cells [6].
- 3D cell cultures including colon epithelial and carcinoma organoids [7] as well as breast, bladder, and prostate cancer organoids [8-10].
- A number of published standardized protocols such as tumor organoid-T-cell co-culture systems [11].

Primocin®
No, Primocin® does not contain Tetracycline.
Primocin® is a preventive antibiotic, active against both Gram+ and Gram- bacteria, mycoplasma and fungi. In other words, Primocin® will NOT induce the elimination of microbial contamination in already infected cells.
Primocin® is shipped at room temperature.
Upon receipt it can be stored at 4°C for 3 month or at -20°C for long-term storage.
Avoid repeated freeze-thaw cycles.
The expiry date is specified on the product label.
Once opened it remains stable for 1 year at -20°C providing you avoid repeated freeze-thaw cycles.
Both antibiotics provide complete protection from microbial contamination however Primocin® was specifically designed for the protection of primary cells whereas Normocin™ is recommended for cell lines.
