本品为经无菌处理的肝素钠(Heparin Sodium)生理盐水溶液,是一种经典的粘多糖硫酸酯类抗凝血药。其抗凝机制是通过与血浆中的抗凝血酶III (AT III) 特异性结合,显著增强AT III对多种凝血因子(尤其是凝血因子Xa和IIa,即凝血酶)的灭活作用,从而达到强效的抗凝效果。同时,肝素钠也能抑制血小板聚集。本产品仅限用于科学研究领域,不得用于临床诊断、治疗或任何人体用途。
适用范围与限制
1. 适用实验
红细胞比容(HCT)测定。
其他需要体外全血抗凝且对白细胞形态和涂片背景无特殊要求的科研实验。
2. 不适用实验
凝血象检查(如PT、APTT测定):肝素会干扰内源性和共同凝血途径,导致结果严重失真。
血液学一般检查与血涂片:肝素可使白细胞发生聚集,影响分类计数;并使血涂片经瑞氏染色后产生淡蓝色背景,干扰镜检观察。
临床诊断。
使用方法
操作前请阅读全部注意事项,并严格遵守无菌操作规范。
1. 常规抗凝比例:推荐抗凝剂与全血的体积比为 1:90 ~ 1:100。
2. 实验特异性调整:某些实验可能要求不同的抗凝比例,请务必根据具体的实验方案或文献进行操作。
3. 操作流程
3.1 穿戴实验服、口罩及一次性无菌手套。
3.2 使用无菌注射器或移液器,按计算好的体积抽取本品,加入洁净的采血管或容器中。
3.3 将新鲜血液采集到含有本品的容器中。
3.4 立即、轻柔并充分地混合均匀。
注意事项
1. 用途限制:本品为科研试剂,严禁用于人体或临床诊断。
2. 实验选择:使用前必须确认实验项目与本品适用范围相符,特别是避免用于凝血检测和血涂片制备。
3. 无菌操作:本品虽经无菌处理,但开封操作必须在洁净环境中进行,并使用无菌器具,以防微生物污染。
4. 比例精确:抗凝剂与血液的比例是实验结果准确性的关键,请使用校准过的精密移液设备。
5. 个人防护:操作时需做好个人防护。如不慎接触皮肤或眼睛,应立即用大量清水冲洗,必要时就医。
6. 生物危害:所有接触过血液的样本、容器及废弃试剂,均应按生物危害废物的处理规定进行高压灭菌或专业处理。
This product is a sterile normal saline solution of Heparin Sodium, a classic mucopolysaccharide polysulfate anticoagulant. Its anticoagulant mechanism involves specific binding to antithrombin III (AT III) in plasma, significantly enhancing AT III's inactivation of various coagulation factors (particularly factor Xa and factor IIa, i.e., thrombin), thereby achieving potent anticoagulation. Additionally, heparin sodium inhibits platelet aggregation. This product is intended for scientific research purposes only and must not be used for clinical diagnosis, treatment, or any human applications.
Scope and Limitations
1. Suitable Experiments
Hematocrit (HCT) determination.
Other research experiments requiring in vitro whole blood anticoagulation with no specific requirements for leukocyte morphology or blood smear background.
2. Unsuitable Experiments
Coagulation profile tests (e.g., PT, APTT determination): Heparin interferes with the intrinsic and common coagulation pathways, leading to severely distorted results.
General hematological examination and blood smears: Heparin can cause leukocyte aggregation, affecting differential counts; it also produces a light blue background on Wright-stained blood smears, interfering with microscopic observation.
Clinical diagnosis.
Usage Instructions
Please read all precautions before operation and strictly adhere to aseptic techniques.
1. General Anticoagulation Ratio: The recommended volume ratio of anticoagulant to whole blood is 1:90 to 1:100.
Example: Take 1 mL of this product, add 90–100 mL of freshly collected whole blood, and immediately invert gently 8–10 times to ensure thorough mixing and anticoagulation. Avoid vigorous shaking to prevent hemolysis.
2. Experiment-Specific Adjustment: Some experiments may require different anticoagulant ratios. Please strictly follow the specific experimental protocol or literature.
3. Operational Procedure
3.1 Wear a lab coat, mask, and disposable sterile gloves.
3.2 Using a sterile syringe or pipette, draw the calculated volume of this product and add it to a clean blood collection tube or container.
3.3 Collect fresh blood into the container containing this product.
3.4 Mix immediately, gently, and thoroughly.
Preautions
1. Use Restriction: This product is for research use only. It is strictly prohibited for human use or clinical diagnosis.
2. Experiment Selection: Before use, confirm that the intended experiment aligns with this product's suitable applications. Avoid use in coagulation tests and blood smear preparation in particular.
3. Aseptic Technique: Although this product is sterile, opening and handling must be performed in a clean environment using sterile instruments to prevent microbial contamination.
4. Precise Ratio: The anticoagulant-to-blood ratio is critical for accurate results. Use calibrated precision pipetting equipment.
5. Personal Protection: Use appropriate personal protective equipment during operation. In case of accidental contact with skin or eyes, rinse immediately with plenty of water and seek medical attention if necessary.
6. Biohazard: All blood-contaminated samples, containers, and waste reagents must be disposed of according to biohazard waste regulations, such as via autoclaving or professional treatment.
