蘑菇是由菌絲體和子實體兩部分組成,菌絲體是營養(yǎng)器官,子實體是繁殖器官,它是真菌中的一種,可分為:食用蘑菇、藥用蘑菇、毒蘑菇。蘑菇的種類非常多,我們今天要講的是雙孢蘑菇的質(zhì)量檢測......
1、課題組介紹:
農(nóng)業(yè)部食用菌產(chǎn)品質(zhì)量監(jiān)督檢驗測試中心(上海)常務副主任和技術負責人邢增濤關于雙孢蘑菇的研究。
農(nóng)業(yè)部食用菌產(chǎn)品質(zhì)量監(jiān)督檢驗測試中心(上海),研究條件重點開展蔬菜、水果、食用菌、糧油產(chǎn)品質(zhì)量安全檢測、農(nóng)產(chǎn)品質(zhì)量安全風險評估、農(nóng)產(chǎn)品質(zhì)量安全風險控制與預警、農(nóng)產(chǎn)品安全保鮮等方面的研究。
2、實現(xiàn)的目的:
根據(jù)實驗要求需把雙孢蘑菇進行研磨以獲得DNA、RNA或蛋白質(zhì)等生物分子,從而進行后續(xù)的分析和檢測。隨著實驗室科研進度的日益加快,手動研磨已無法滿足科研工作的需要,故而選擇上海凈信全自動冷凍研磨儀進行樣品研磨。
3、實驗準備
實驗地點:實驗室
樣品:雙孢蘑菇
儀器:全自動冷凍研磨儀(上海凈信,JXFSTPRP-CL)
配件:聚乙烯研磨罐,配套研磨珠.
耗材:液氮
JXFSTPRP-CL(專利產(chǎn)品,仿冒必究!ZL2017305264903)樣品處理的三大關鍵要素:
○高效率研磨——一批處理多達192個樣品
○低溫研磨——研磨溫度可自定義調(diào)節(jié)
○不破壞樣品成分——低溫保護樣品成分
產(chǎn)品應用:
·提取核酸/蛋白質(zhì),低溫研磨樣品能夠有效抑制核酸降解、保留蛋白質(zhì)活性。
·分析藥效成分,藥物有效成分的異構體之間常常存在重大區(qū)別。低溫研磨可預防分子因壓力和受熱而降解。
·減少樣品揮發(fā),低溫研磨能顯著減少樣品的揮發(fā),更完整保留樣品成分含量
·研磨韌性/硬性樣品,對于高韌塑料、高強塑料、樹脂等難研磨樣品,低溫研磨可大大提高研磨效果及效率
4、實驗步驟:
1.準備好聚乙烯研磨罐;配套研磨珠.
2.把準備好的雙孢蘑菇放入聚乙烯研磨罐中放入配套研磨珠蓋好,放入液氮中浸泡若干分鐘;
3.把裝雙孢蘑菇的罐子侵泡后,取出放入冷凍研磨儀中,設置參數(shù)啟動,程序結束后即可破碎為粉末狀。
5.研磨完成后繼續(xù)做后續(xù)實驗。

5、注意事項:
1、研磨罐和研磨珠需充分清洗干凈并烘干備用;則研磨罐和研磨珠要確保滅酶;
2.每個研磨罐研磨樣品量一般遵循原則:樣品體積不超過離心管容積的三分之一。
