Cell Culture Square Bottles: A More Convenient Choice for Cell Cultivation
As a vital nutrient for cell growth, calf serum plays a critical role in cell culture. Cells are highly sensitive to their growth environment, and the use of contaminated serum can hinder their proliferation. Therefore, calf serum bottles are essential for protecting the serum from contamination.

Typically, calf serum bottles are made from transparent PET material through a stretch-blow molding process. This material provides excellent low-temperature resistance, making it suitable for storing serum at low temperatures. After production, the bottles often undergo special electron beam sterilization to eliminate any microorganisms, ensuring a clean environment for the serum storage.
Calf serum contains key components such as proteins, peptides, and hormones. The proteins include albumin, globulins, alpha-macroglobulin (which inhibits trypsin activity), fetuin (which promotes cell attachment), transferrin (which binds iron ions to reduce toxicity and aid in cell utilization), and fibronectin (which encourages cell attachment and growth). The peptides primarily consist of growth factors that promote cell growth and division. The most significant of these are platelet-derived growth factor (PDGF), fibroblast growth factor (FGF), epidermal growth factor (EGF), and nerve growth factor (NGF). Although present in small amounts in serum, these growth factors play an important role in cell development and proliferation. Hormones, including insulin, insulin-like growth factors, growth hormones, and hydrocortisone, also contribute to the stimulation of cell growth.
The proper storage of calf serum is closely related to the quality of the calf serum bottles. In summary, the serum bottles play a crucial role in ensuring the safe storage of serum and preventing contamination from the external environment.
