and the new conceptions such as product sale exchange coefficient were posed and quantitated in the system . and the way of concentric circles survey to obtain the basic data was introduced in the thesis 提出了產(chǎn)品銷售交易系數(shù)、產(chǎn)品銷售相對交易系數(shù)的概念和定量化表達方式,以及同心圓基礎(chǔ)數(shù)據(jù)調(diào)查方法。
in this assay, a tetrazolium salt ( mtt ) is converted to a blue formazan product by enzymes active only in living cells . the amount of formazan produced can be quantitated using a microtitre plate reader rta一yqrl蛋白的細胞毒性約為rra蛋白的2一40倍,提示高爾基體可能是毒素在細胞內(nèi)轉(zhuǎn)運過程中的重要一環(huán)。
5 . detection : the samples were extracted with ethyl ether . the lidocaine in the sample was qualitated by rf and a tlc scanning spectrometry, quantitated by a tlc scanning chromatography and a two points external standard method or a standard curve method 5、利多卡因檢測方法:樣品堿化處理后,乙醚提取,薄層掃描檢測,根據(jù)利多卡因的rf值結(jié)合光譜掃描圖定性,外標兩點法或標準曲線法定量。
immature dc generated from mouse bone marrow by culturing in gm-csf and il-4 for 5 days were incubated with hs-exo or exo for 48 hours, and then were collected for phenotypical analysis and phagocytosis of ova-fitc by facs technique . cytokines in the culture supernatants were quantitated using elisa . in the experiment of mlr to detect 熱休克誘導細胞表達熱休克蛋白,對exosomes中熱休克蛋白的檢測發(fā)現(xiàn),在exo和hs一exo中均存在hsp60、hsp70和hsp90,其中hs一exo中hsp6o和hsp90的含量顯著高于exo,hsp70的
through charoma theory and metal-bearing ores " color index analysis, the color of the turquoise is quantitated . crystal field spectra of cu2 + ion have been analysed and compared with the oretical calculations, the results show that the basic color of turquoise ( azure ) is related to the existence of cu2 + octahedron . in this charpter, quantum mineralogy theory is used in quantity 通過吸收光譜實驗,利用量子礦物學的有關(guān)知識,對綠松石中銅離子的晶體場譜進行了計算,并利用晶體場理論解釋了綠松石吸收光譜,揭示了綠松石顏色形成的主要原因是聯(lián)系著晶體場譜的顏色:過渡金屬銅離子對綠松石的顏色起主要作用??決定了綠松石的基本色調(diào)(天藍色)。
