Media & Supplements

Cell culture media, sera, and supplements for primary and immortalised mammalian cultures

Cell culture media, sera, and supplements for primary and immortalised mammalian cell culture. The category covers ready-to-use complete media formulated for specific cell types (endothelial, fibroblast, hepatocyte, immune subsets), basal media (DMEM, RPMI, EMEM variants), individual growth factor and cytokine supplements, antibiotic-antimycotic mixes, and specialty additives like polylysine coating, freezing media, and tyrode's or alsever's solutions. Buyers are primary-cell labs, organoid and 3D culture groups, biopharma cell-line development teams, and core facilities maintaining stock cultures. Choice drives experimental reproducibility more than most researchers realise; switching media formulation between studies introduces a common irreproducibility variable.

Match the medium to the cell type first, then weigh four further dimensions: serum content (serum-free is preferred for biologic relevance and reproducibility; FBS-containing is preferred for ease of culture; specify exosome-depleted for exosome studies; specify defined when downstream assays are sensitive to undefined components), validated cell type list (suppliers vary in which cell types each formulation has been validated against), antibiotic preference (penicillin-streptomycin standard; gentamicin or amphotericin for mycoplasma-prone primary cells), and supply chain reliability (long-term studies require consistent lot supply). Elabscience has the broadest tissue-specific complete-medium catalogue across human, mouse, and rat; ABM covers transformed and cancer cell line media; Innoprot specialises in primary endothelial and vascular cells. For long-term cultures source from a single supplier per cell type to minimise batch variance.
