目的 :对鹿角粉、含鹿角粉的乳宁冲剂、乳宁冲剂阴性样品进行检测。方法 :采用聚丙烯酰胺凝胶电泳法 (Polyacrylamidegelelectrophoresis,简称PAGE) ,以 pH8.3系统制备凝胶及缓冲液 ,浓缩胶浓度 2 .5 % ,分离胶浓度 15 %。 结果 :乳宁冲剂电泳图谱中有 4个蛋白斑点。结论 :实验取得了较满意的效果 ,为该类样品的鉴别提供了较可靠的方法。
OBJECTIVE: To test the antler powder, the milk powder containing antler powder and the negative sample of milk powder. Methods: Polyacrylamide gel electrophoresis (PAGE) was used to prepare gel and buffer at pH 8.3. The concentration of gel was 2.5% and the concentration of gel was 15%. Results: There are 4 protein spots in the milk powder gel electrophoresis pattern. Conclusion: The experiment has achieved satisfactory results, providing a more reliable method for the identification of such samples.
