Bacterial Cell Wall Degradation Technology
Bacterial cell wall degradation is a key technique that disrupts peptidoglycan and its outer structures through enzymatic, chemical, or physically assisted methods, allowing cellular contents to be released or enabling the formation of protoplasts/spheroplasts. This technology is commonly used ...
细菌细胞壁降解技术
细菌细胞壁降解是通过酶学、化学或物理辅助方式破坏肽聚糖及其外层结构，使细胞内容物释放或形成原生质体/球形体的关键技术。该技术常用于DNA/RNA提取、蛋白释放、细胞壁组分分析、细菌鉴定、抗菌机制研究和细胞壁合成抑制剂评价。 ...
Effects of Cell Sample Preservation Systems on Morphological Integrity, Anticoagulant Stability, and Analytical Results
Once a cell sample enters a preservation system, the analytical result is no longer determined solely by its original biological state, but is instead jointly influenced by the anticoagulation mode, osmotic environment, buffering conditions, degree of metabolic suppression, and processing ...
细胞样本保存体系对形态保持、抗凝稳定与检测结果的影响
细胞样本进入保存体系后，检测结果已不再仅由原始生物学状态决定，而是同时受到抗凝方式、渗透压环境、缓冲条件、代谢抑制程度和处理时效的共同影响。保存体系选择不当时，首先受损的通常不是“是否还能检测”，而是形态边界、细胞分散性、抗凝完整性和结果解释的可信度。 ...
Systematic Anticoagulant Selection Strategy
Anticoagulants are auxiliary substances used to prevent blood from clotting ex vivo by inhibiting activation of coagulation factors, potentiating endogenous anticoagulant pathways, or reducing the availability of Ca²⁺.
抗凝剂的系统化选择策略
抗凝剂（Anticoagulant）是一类通过抑制凝血因子活化、增强内源性抗凝通路或螯合Ca²⁺等方式阻止血液凝固的化学试剂或物质。
Why Is EDTA So Widely Used?
EDTA (ethylenediaminetetraacetic acid) is ubiquitous—from blood collection tubes and cleaners to food formulations and laboratory buffers. Its hexadentate coordination and strong, broad-spectrum metal chelation underpin its use across medicine, the life sciences, analytical chemistry, and ...
EDTA为何应用如此广泛？
在采血管、清洁剂、食品配方乃至实验室缓冲液中，常能见到EDTA（乙二胺四乙酸）的身影。其六配位、强而广谱的螯合能力是横跨医学、生命科学、分析化学与工业体系的根本原因。本文系统阐述EDTA的性质、机理与关键应用，并给出实操注意事项与替代方案。 ...
Peripheral blood anticoagulant, EDTA or heparin?
Peripheral blood is one of the commonly used samples in our flow experiments. Since blood coagulates in the presence of coagulation factors after it is isolated from the body, the collection of peripheral blood samples requires the use of blood collection tubes with anticoagulants or the ...
外周血抗凝剂，选EDTA or 肝素？
外周血是我们流式实验中常用到的样本之一。由于血液离体后会在凝血因子的作用下凝固，采集外周血样本时，需要使用带抗凝剂的采血管，或采集后立即加入抗凝剂。通常，我们流式实验中用到的抗凝剂有两种：EDTA和肝素。
