ES cell is a kind of cell isolated from the early embryo (before the protoenteric embryo stage) or the primitive gonad, which has the characteristics of unlimited proliferation, self-renewal and multidirectional differentiation in vitro. Both in vitro and in vivo, embryonic stem cells can be induced to differentiate into almost all cell types in the body. ES has strict requirements on serum nutrients and endotoxin content, so we must be careful in screening fetal bovine serum. BIOEXPLORER® specially produces ES special serum for ES, which is rich in nutrition and low in endotoxin (endotoxin ≤5EU/ml).Low in antibodies and high in growth factors,It completely conforms to the requirements of ES cell growth. This material originates from USDA-approved sources and goes through the same filtration schemes and final quality-control testing as our other grades. This Fetal Bovine Serum is filtered through sequential 100 nm (0.1 µm) pore size-rated filters. Before dispensing, each lot of serum is pooled using true pool technology to ensure uniformity and consistency between bottles. CAUTION Not for human or animal therapeutic use. Uses other than the intended use may be a violation of local law. |
