Analysis Note
All lots of PromoCell Hematopoietic Progenitor Media are subjected to comprehensive quality control tests using primary human mononuclear cells as well as purified hematopoietic progenitor cells from cord blood. Each lot of PromoCell HPC Expansion Medium DXF is tested for the ability to support the expansion of hematopoietic progenitor cells with a primitive phenotype. Each lot of PromoCell Hematopoietic Progenitor Medium is tested for the capacity to induce directed differentiation into hematopoietic lineages using purified CD34+ progenitor cells from cord blood. Approved in-house lots of media are used as a reference. In addition, all lots of media have been tested for the absence of microbial contaminants (fungi, bacteria, mycoplasma).
