β-巯基乙醇对细胞生长有重要作用,可使血清中含硫化合物还原成谷胱甘肽,能诱导细胞增殖和延缓细胞衰老,为非特异性的激活作用;同时避免过氧化物对细胞的损伤。另一个重要作用是促进分裂原的反应和DNA合成,增加植物凝集素(PHA)对淋巴细胞的转化作用,已广泛应用于杂交瘤技术,目前也开始用于一些难培养的细胞。
该产品为细胞培养级别,无菌包装。浓度为55mM,溶解于D-PBS后过滤除菌。巯基还原剂在培养基中可以保护蛋白中的二硫键不被氧化,可降低氧对细胞产生的氧化损伤。作为培养基的添加剂,仅用于科研使用。
使用要点
1. 浓度适配:需要根据细胞类型调整使用终浓度,如THP-1细胞需0.05 mM。
2. 稳定性: 溶液易氧化,需避光保存,添加到培养基后24小时内使用。 长期培养建议每日补充。
3. 毒性控制:浓度>100 μM可能诱发线粒体毒性,需通过MTT/CCK-8实验优化。
4. 血清依赖性:在无血清培养基中作用更显著,因其缺乏天然抗氧化成分。
注意事项
1. 巯基还原剂有毒,而且味道很大,操作的时候要带手套和口罩。
2. 试剂开封后请尽快使用,以防影响后续实验效果。
3. 本产品仅限于专业人员的科学研究用,不得用于临床诊断或治疗,不得用于食品或药品,不得存放于普通住宅内。
β-Mercaptoethanol plays an important role in cell growth. It can reduce sulfur-containing compounds in serum to glutathione, induce cell proliferation, and delay cellular senescence, acting as a non-specific activator. At the same time, it protects cells from damage caused by peroxides. Another critical function is its ability to promote mitogen responses and DNA synthesis, and to enhance the transformation of lymphocytes by phytohemagglutinin (PHA). It has been widely used in hybridoma technology and has recently also been applied to some difficult-to-culture cell types.
This product is of cell culture grade with sterile packaging. It is prepared at a concentration of 55 mM, dissolved in D-PBS and sterile-filtered. As a thiol reducing agent, it protects disulfide bonds in proteins from oxidation in culture medium and alleviates oxidative damage to cells caused by oxygen. It serves as a medium additive for research purposes only.
Key Points for Use
1. Concentration optimization: The final working concentration should be adjusted according to cell type. For example, THP-1 cells require 0.05 mM.
2. Stability: The solution is susceptible to oxidation and should be stored protected from light. Once added to the culture medium, it should be used within 24 hours. For long-term culture, daily supplementation is recommended.
3. Toxicity control: Concentrations above 100 μM may induce mitochondrial toxicity, so optimization via MTT/CCK‑8 assays is necessary.
4. Serum dependence: Its effects are more pronounced in serum‑free media, as these lack natural antioxidant components.
Precautions
1. This thiol reducing agent is toxic and has a strong pungent odor. Wear gloves and a respirator/mask during all handling operations.
2. Use the reagent promptly once opened to avoid compromising experimental results.
3. This product is intended solely for scientific research by qualified professionals. It shall not be used for clinical diagnosis or treatment, food or pharmaceutical manufacturing, nor stored in residential premises.
