小球藻生长因子，缩写 CGF（Chlorella Growth Factor），是由优质蛋白核小球藻经细胞破碎、分级分离、浓缩萃取得到的水溶性生物活性复合物。CGF 富集于小球藻快速增殖阶段，在微藻研究领域受到广泛关注。 CGF 在小球藻中含量稀缺，每 100 g 小球藻干粉中 CGF 含量约 4 g，组分包含核蛋白、核酸、游离氨基酸、多糖、糖蛋白、多种维生素及植物内源活性物质等，是一类成分丰富的天然复合原料。 现有文献研究提示，核酸参与生物体内 RNA、DNA 代谢过程；CGF 常作为科研受试物，用于细胞生物学、营养生化、微生物培养等方向的体外研究。本品为科研用原料，不可用于人体疾病预防、治疗或抗衰老保健用途。

Chlorella Growth Factor (CGF) is a water‑soluble bioactive complex prepared from high‑quality Chlorella pyrenoidosa via cell disruption, fractional separation, concentration and extraction. CGF accumulates during the rapid proliferation phase of chlorella and has attracted widespread attention in microalgae research.
CGF is a scarce fraction in chlorella: approximately 4 g CGF is contained in every 100 g of chlorella dry powder. It consists of nucleoproteins, nucleic acids, free amino acids, polysaccharides, glycoproteins, multiple vitamins and endogenous plant active substances, serving as a naturally derived complex raw material with abundant constituents.
Published literature suggests that nucleic acids participate in cellular RNA and DNA metabolism. CGF is commonly used as a test substance for in vitro research in cell biology, nutritional biochemistry, microbiology and related fields.
This product is a research‑grade raw material. It is not intended for the prevention or treatment of human diseases, nor for anti‑aging or health‑care applications.
