在蛛絲馬跡中尋找證據(jù),在重重迷霧中探索真相。一系列重大案件的成功破獲,都離不開高科技的助力,提取DNA破案就是其中一項比較重要的方式。對于人體DNA的提取中其中有一項就是牙齒的研磨,傳統(tǒng)的一些方式是拿錘子砸,取雜碎后的粉末做后期的樣品分析,海南省公安廳就是如此。在了解到上海凈信研磨儀后,用戶選擇了上海凈信JXFSTPRP-24L研磨儀。
特點:全新一代JXSTPRP®全自動組織研磨儀,采用進口電機,防腐材質(zhì),增強型運動軸等多種提升。性能全面優(yōu)化,外形更加美觀!
JXFSTPRP-L系列組織研磨儀(專利產(chǎn)品,仿冒必究ZL2019301918692)是一種特殊的、快速的、高效率的、多試管的一致系統(tǒng)。它能將任何來源(包括土壤、植物和動物的組織/器官、細菌、酵母、真菌、孢子、古生物標本、骨骼等)的原始DNA、RNA和蛋白質(zhì)進行提取和純化。
這款儀器采用三維一體8字形振蕩方式,研磨更充分,穩(wěn)定性更好,效率更高,1分鐘內(nèi)完成2×24、2×48、4×96個樣品的研磨;同一組織樣本設(shè)定相同程序,獲得相同的研磨效果。操作簡便、安全性高、無交叉污染、低噪音。
實驗案例:
機型:JXFSTPRP-24L
實驗地點:海南省公安廳刑偵技術(shù)總隊
樣品:待研磨的人體牙齒一顆
配件:不銹鋼研磨罐一套
實驗步驟:
一、若干ml不銹鋼研磨罐清洗并滅菌
二、待研磨的人體牙齒裝入滅菌后的不銹鋼研磨罐中
三、擰緊研磨罐,裝入研磨儀中。注意配平
四、設(shè)置程序
五、待程序結(jié)束后取出研磨罐。
實驗結(jié)果:
結(jié)語:用戶對上海凈信研磨儀評價很高,解決了傳統(tǒng)的手工處理帶來的困擾,樣品得率高,而且簡單輕松,操作簡便。實驗結(jié)果滿意,為公安刑偵案件的偵破帶來進展。同時體現(xiàn)了上海凈信的社會責(zé)任!
