LIF is a cytokine that induces macrophage differentiation. LIF, in conjunction with BMP2, acts on primary fetal neural progenitor cells to induce astrocytes.

  • High purity: minimizes interference from other proteins or contaminants
  • High biological activity: more results with less protein
  • Proven compatibility: Gibco proteins bioassayed with Gibco media
  • High Purity Recombinant Bioactive Protein: to help ensure Gibco growth factors are of the highest quality, each protein is analyzed for purity along with structural homogeneity to ensure a biologically active protein
  • High Biological Activity: in-house activity testing of Gibco recombinant proteins includes cell proliferation, cytotoxicity, chemotaxis, calcium flux, secondary cytokine up-regulation, induction of surface antigen expression, anti-viral, and protease assays; specific activity is determined by measuring the LIF dose-dependent proliferation of Human TF-1 cells
