StemImmune LLC Verified partner
StemImmune LLC, based in Livermore, California, develops and manufactures recombinant cytokines and growth factors for stem cell, hematopoiesis, immunology and cell therapy research. Its core range is expressed in human HEK293 cells and supplied tag-free and animal-free, for culture systems in which bacterial host-cell contaminants, non-native sequences or animal-derived components are unwanted.

On eBioHippo, StemImmune supplies a focused panel of human cell-expressed proteins: the morphogens and growth factors used for directed differentiation of pluripotent stem cells, the hematopoietic cytokines used to derive and expand blood progenitors, and the interleukins, colony-stimulating factors and interferons used in immune cell culture. The company also offers cell line development and protein purification services.
What makes StemImmune LLC different
Human cell-expressed recombinant proteins
