随着酵母在基础研究与工业应用中的广泛使用，对高质量实验试剂的需求日益增加。“适用于酵母”系列试剂正是为此而开发，确保实验过程稳定可靠。
With the widespread use of yeast in basic research and industrial applications, the demand for high-quality experimental reagents continues to grow. The “Suitable for Yeast” series of reagents has been developed to ensure stable and reliable experimental processes.
内毒素（Endotoxin）是革兰氏阴性菌细胞壁的脂多糖（LPS），在细菌死亡或裂解时释放。它可通过TLR4–MD2–CD14受体复合物被免疫系统识别，激活NF-κB和MAPK信号通路，引发炎症因子（如TNF-α、IL-6）的上调。研究表明，即使在≥0.25EU/mL的水平下，内毒素即可显著干扰哺乳动物细胞实验、蛋白功能检测及免疫学研究。 ...
Endotoxins (lipopolysaccharides, LPS) are components of the outer membrane of Gram-negative bacteria, released upon bacterial death or lysis. They can be recognized by the TLR4–MD2–CD14 receptor complex, activating NF-κB and MAPK signaling pathways, and inducing the upregulation of inflammatory ...
Analysis of Titration solution refers to ready-to-use (or concentrate-to-dilute) standardized titrants supplied specifically for analytical titrimetry, each lot accompanied by a certificate of analysis (true concentration, uncertainty, and traceability). In global literature this map to ...
