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 of Primocin™:

  • 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].
