Supplements & Additives (Serum, Growth Factors, Cytokines)

Supplements and additives are crucial components in cell culture, enabling scientists to tailor media to the specific nutritional and signaling needs of different cell types. This subcategory includes essential supplements such as fetal bovine serum (FBS), albumin, amino acids (e.g., glutamine, methionine), vitamins, and lipids, as well as bioactive molecules like growth factors (EGF, FGF, VEGF) and cytokines (IL-2, TNF-±, IFN-≥) that drive cell signaling and functional differentiation. These reagents are indispensable across a wide spectrum of research areas including stem cell differentiation, cancer biology, immunotherapy, neurobiology, and biomanufacturing. For example, growth factors play a key role in maintaining pluripotency in stem cell cultures or inducing lineage-specific differentiation, while cytokines are vital for immunological assays and expansion of T cells in adoptive cell therapies. Used in both adherent and suspension culture systems, these additives allow researchers to fine-tune the metabolic environment, promote cell viability, and achieve reproducible functional outcomes. Many workflowsincluding 3D culture, organoid development, gene therapy vector production, and high-throughput screeningrequire precise formulation of supplements to mimic physiological conditions. On Wasteless Bio, surplus and unopened supplement stocks can find renewed use in other labs, offering a sustainable way to reduce biological waste and procurement costs. All products include clear descriptions and specifications, helping buyers select the appropriate reagents for their experimental design. This supports both scientific reproducibility and environmental responsibility in modern research labs.
