General description

Methylisothiazolinone, also known as 2-Methyl-4-isothiazolin-3-one, is a potent synthetic biocide and preservative belonging to the group of isothiazolinones. It effectively controls microbial growth and acts as a broad-spectrum antibiotic, similar to the function and performance of bromonitrodioxane. It is effective against both gram-positive and gram-negative bacteria, as well as yeast and fungi. Additionally, it serves as an antifouling biocide, an antimicrobial agent, and an antifungal agent. 2-Methyl-4-isothiazolin-3-one is utilized in cell biology and biochemical applications to effectively prevent the growth of bacterial contaminants, ensuring the purity of cell lines.

Application

Methylisothiazolinone (MIT) has been used:
  • in research on the effects of the N-methyl D-aspartate (NMDA) receptor antagonist kynurenic acid on human cortical development
  • as a cytotoxic substance to investigate its effect on bronchial epithelial cells (BEAS-2B cells) and its role in apoptotic cell death
  • to research the effects of tyrosine phosphorylation on focal adhesion kinase (FAK) activity in the development of neural axons and dendrites

Biochem/physiol Actions

Mode of Action: Inhibits the growth of microorganisms by disrupting the normal function of microbial cells and interfering with essential cellular processes

Activity Spectrum: Active against Gram-positive and Gram-negative bacteria, as well as fungi, when used in combination with methylchloroisothiazolinone (MCI)

Features and Benefits

  • Ready available solution reduce the need for preparation time
  • Commonly used in Cell Biology and Biochemical applications
  • High quality antibiotic suitable for mulitple research applications
