ion exchange analysis
解釋
離子交換分析法-
Strain bl21, and gene expression was induced by iptg. the target proteins were directed into the periplasmic space by the staphylococcal protein a signal sequence preceding the rgd - hirudin gene. using ion exchange chromatography and gel filtration chromatography, the chimera proteins were purified, and both of them showed a single band in tricine - sds - page. the results of activity analysis suggested that these two chimera proteins not only have antithrombin activities, but gain platelet aggregation inhibitory activities as well
通過離子交換層析和凝膠過濾層分別對兩種嵌合體蛋白進行純化，純化產物在tricine - sds - page中都顯示為單一條帶。活性分析結果表明兩種嵌合體蛋白在保留水蛭素抗凝血酶活力的同時，還呈現抗血小板聚集活性。 -
The hwtx - i gene was chemically synthesized according to its known cdna sequence, the gene was inserted into vector ppic9k which contained aoxj promotor and the sequence of a secreting signal peptide - a - factor, the cloning ppic9k / hwtx - i was constructed and confirmed by two - step pcr and dna sequence analysis, then it was transformed into host strain gs115, a his + muts cell line was screened and multicopy transformants were screened by various g418 concentrations, the multicopy transformant was named gh1. gh1 was cultivated in flasks. after 6 days of induction by 0. 5 % methanol, the supernatant was checked by 16. 5 % tricine - sds page, which showed there was a band in the position of 3. 5 - 6. 1kd, then it was isolated and desalted by ultrofiltration followed by ion exchange of cm column, after reverse phase hplc of ci8 and vacuum drying, the purified rhwtx - 1 was obtained which was proved to be correct recombinant hwtx - i by tricine sds - page, maldi - tof mass spectrometry, amino acid composition analysis, the n - terminal amino acid sequence and its biological activity, the final field of the purified rhwtx - i was about 80mg / l, accounting for 23. 6 % of it total secretory proteins
將帶有hwtx -基因的ppic9k經blgii線性化后，轉化酵母宿主菌gs115原生質體后經篩選陽性克隆並經表型鑒定為his ~ + mut ~ s酵母菌，進一步用遺傳毒素g418篩選多拷貝的轉化菌株，命名為gh1 ；將gh1甲醇酵母菌用0 . 5的甲醇誘導表達，發酵上清經90飽和度的（ nh _ 4 ） _ 2so _ 4沉澱， yw - 3 （ mwc03000 ）的超濾膜超濾，再經cm陽離子交換， c _ （ 18 ）反相hplc純化得到分子量為4kd左右的組分，其中4289 . 05的組分經質譜鑒定，氨基酸組成分析和序列測定為正確的表達產物，生物學活性表明其活性為天然毒素活性70 % ，表達量為80mg / l 。 -

In this thesis, organic - montmorillorite ( org - mmt ) was obtained - by an ion - exchange reaction between na + - montmorillorite ( na + - mmt ) and alkyl ammonium bromide, leading to increase the basal spacing of montmorillonite. xrd analysis indicated that alkylammonium ions had already exchanged with na + ions in na - montmorillonite and long alkyl - chains had entered into the gallery of montmorillorite
X -射線衍射（ xrd ）分析結果表明有機胺陽離子已同蒙脫土中的鈉陽離子發生離子交換作用，烷基長鏈進入蒙脫土層間，導致層間距擴大，並使蒙脫土層間親水性轉變成親油性。 -
