A Practical Guide to UHPLC-MS-Grade Solvents
These solvents/reagents are manufactured and QC-tested specifically for ultra-high-performance LC (sub-2 µm particles, high pressure) with mass-spectrometry detection. They have very low non-volatile residue, ppb-level metals, minimal UV/MS background, and sub-micron particulates so columns and ...
UHPLC–MS级溶剂实用指南
这些溶剂/试剂是专为配合质谱（MS）检测的超高效液相色谱（UHPLC；< ...
For SDS-PAGE
SDS-PAGE endows proteins with approximately uniform charge density under denaturing conditions via sodium dodecyl sulfate and separates them by apparent molecular weight through the gel’s sieving effect. It is a foundational technique for protein identification, purity assessment, and quality ...
For SDS-PAGE
SDS-PAGE以十二烷基硫酸钠在变性条件下赋予蛋白近似相同的电荷密度，通过凝胶分子筛效应按表观分子量进行分离，是蛋白定性、纯度评估与质量控制的基础技术。体系对缓冲配方、凝胶交联度、表面活性剂与还原剂纯度高度敏感；任一环节失配都会引起条带弥散、迁移异常或定量误差，影响后续转膜、免疫检测与质谱分析的准确性与可重复性。 ...
For IHC (Immunohistochemistry)
Immunohistochemistry (IHC) integrates tissue morphology with immunology to visualize target molecule expression on tissue sections via antigen–antibody specific recognition. It is widely used in basic research, drug development, pathological validation, and digital pathology analysis. IHC is ...
解析基础级（Basic-Grade）试剂：实验室中经济高效的得力助手
基础级试剂（常称为实验级、实用级或化学纯试剂），是指符合生产企业内部纯度标准的化学品。这类试剂主要应用于对实验精度与痕量杂质要求不苛刻的场景，可类比为化学实验工具箱中的"多用途工具"——性能可靠且适用性强，但不宜用于精密实验。 ...
适用于免疫组织化学(for IHC)
免疫组织化学是将组织形态学与免疫学结合的关键技术，通过抗原–抗体特异性识别在组织切片上可视化目标分子表达，广泛用于基础研究、药物研发、病理学验证与数字病理分析。IHC对样本前处理、抗原修复、阻断、抗体孵育、显色与封片等各环节的化学环境高度敏感；任何配方不当、杂质量不稳或批次波动，都会导致背景升高、信号偏移或定位失真，从而影响可重复性与跨平台可比性。 ...
Understanding Basic-Grade Reagents: The Cost-Effective Workhorse of the Lab
Basic-Grade Reagents, also known as Laboratory Grade, Practical Grade, or Chemically Pure (CP), are chemicals that meet a manufacturer’s internal specifications for purity. They are intended for applications where high precision and the absence of trace impurities are not critical to the ...
