QBSF-60 is a proprietary serum-free medium that supports the expansion of human hematopoietic stem/progenitor cells.

QBSF-60 supports CD34+ cells derived from normal bone marrow, cord blood, peripheral blood stem cells mobilized with cytokines for ex-vivo expansion and differentiation to erythrocytes, granulocytes, and lymphocytes.

  • Serum-Free
  • Contains L-glutamine and Phenol Red
  • Endotoxin, mycoplasma, and performance tested
  • Sterile Filtered


QBSF-60 can be used for the maintenance of human hematopoietic stem cell culture, to support CD34 cell proliferation and differentiation to multi-lineage cells, and to support human umbilical and blood vessel endothelial cells

The QBSF products have been used successfully in different cell culture applications; investigators are encouraged to explore new uses.
