是否无菌:是
硫酸鱼精蛋白(Protamine Sulfate)系从鱼类新鲜成熟精子中提取纯化得到的一种碱性蛋白质硫酸盐,分子中富含精氨酸残基,带有大量强碱性基团。本品可与酸性黏多糖——肝素通过静电结合形成稳定的复合物,从而中和肝素的抗凝活性,使其失去抗凝血作用。适用于含肝素样品的抗凝中和、肝素活性去除等科研用途。
使用方法
1.根据实验需要,按适当比例将本品加入含肝素的样品中,充分混匀后室温放置数分钟即可。
2.建议初次使用时先通过预实验确定最佳用量;取用后请立即盖紧瓶盖。
注意事项
1.本产品仅供科研使用,请勿用于临床诊断或治疗,不得用于食品或药品。
2.为了您的安全和健康,请穿实验服并佩戴一次性手套操作.
3.试剂开封后请尽快使用,如发现溶液浑浊、变色或出现沉淀,请勿继续使用。
Is it sterile: Yes
Protamine Sulfate is a basic protein sulfate extracted and purified from fresh mature sperm of fish. It is rich in arginine residues and carries a large number of strongly basic groups. This product binds electrostatically to heparin, an acidic mucopolysaccharide, forming a stable complex that neutralizes heparin's anticoagulant activity. It is suitable for research purposes such as anticoagulation neutralization of heparin-containing samples and removal of heparin activity.
Instructions for Use
1.Add this product to heparin-containing samples at an appropriate ratio according to experimental needs. Mix thoroughly and let stand at room temperature for several minutes.
2.For first-time use, determine the optimal amount through a preliminary experiment. Close the cap tightly immediately after use.
Precautions
1.This product is for research use only. It must not be used for clinical diagnosis or treatment, nor in food or pharmaceuticals.
2.For your safety and health, wear a lab coat and disposable gloves during operation.
3.Use the reagent as soon as possible after opening. Do not use if the solution appears turbid, discolored, or contains precipitate.
