本产品通过特殊工艺去除血清中的内源性激素(如雌激素、雄激素、生长激素等),适用于对激素敏感的细胞培养及研究(如干细胞培养、内分泌相关实验、激素受体研究等)。产品经过严格质量控制,确保无外源病毒、支原体、细菌污染,内毒素含量<5 EU/mL。
去激素工艺说明
去激素方法:采用分子筛层析(Size-exclusion chromatography)、炭吸附(Charcoal stripping)或免疫亲和层析法,特异性去除血清中内源性激素。
保留成分:保留血清中必要的生长因子、蛋白质、维生素及矿物质,确保细胞培养的基础营养支持。
验证标准:通过ELISA 或质谱法检测,确保激素残留量低于检测限 (如:激素<5 pg/mL 或未检出)。
质量控制指标
|
适用范围
激素敏感型细胞培养(如乳腺癌细胞、前列腺癌细胞、干细胞等)。
使用建议
解冻方法:推荐4℃缓慢解冻,避免高温快速融化导致蛋白沉淀。
添加比例:常规细胞培养建议添加5%-20%,具体浓度需根据细胞类型优化。
注意事项:使用前无需热灭活(热灭活可能破坏生长因子)。
开封后建议分装保存,避免反复冻融。
若发现浑浊或沉淀,可离心(2000×g,10 分钟)后取上清使用

Premium Fetal Bovine Serum (Hormone‑Depleted) employs specialized processes to remove endogenous hormones (e.g., estrogens, androgens, growth hormones, etc.) from serum, making it suitable for hormone‑sensitive cell culture and research applications (such as stem cell culture, endocrine‑related experiments, and hormone receptor studies). It undergoes rigorous quality control to ensure freedom from exogenous viruses, mycoplasma, and bacterial contamination, with an endotoxin level of <5 EU/mL.
Hormone‑Depletion Process Description
Depletion methods: Size‑exclusion chromatography, charcoal stripping, or immunoaffinity chromatography are used to specifically remove endogenous hormones from the serum.
Retained components: Essential growth factors, proteins, vitamins, and minerals are preserved to maintain basal nutritional support for cell culture.
Validation criteria: Hormone residual levels are verified by ELISA or mass spectrometry to be below the detection limit (e.g., hormones <5 pg/mL or not detectable).
Quality Control Specifications

Applications
Hormone‑sensitive cell culture (e.g., breast cancer cells, prostate cancer cells, stem cells, etc.).
Usage Recommendations
Thawing: Slow thawing at 4°C is recommended; avoid rapid warming at high temperatures to prevent protein precipitation.
Supplementation ratio: For routine cell culture, a 5%–20% addition is suggested; the optimal concentration should be determined based on the specific cell type.
Note: Heat inactivation is not required before use (heat inactivation may destroy growth factors).
After opening, aliquot and store to avoid repeated freeze‑thaw cycles.
If turbidity or precipitate is observed, centrifuge at 2,000×g for 10 minutes and use the supernatant.
Batch‑to‑Batch Consistency Assurance
A complete Certificate of Analysis (COA) is provided for each batch, including key data on hormone residuals, endotoxins, microbiological parameters, etc. Strict donor screening and process standardization ensure stable performance across batches.
Intended Use and Disclaimer
The product is intended for research or industrial use only; it is not indicated for clinical treatment. Users are responsible for validating the suitability of the serum in their own experimental systems. The manufacturer assumes no liability for deviations in experimental results arising from improper handling or operation.
