蛋白質(zhì)的抽提通常選擇適當(dāng)?shù)木彌_液溶劑把蛋白質(zhì)提取出來(lái)。抽提所用緩沖液的pH、離子強(qiáng)度、組成成分等條件的選擇應(yīng)根據(jù)欲制備的蛋白質(zhì)的性質(zhì)而定。如膜蛋白的抽提，抽提緩沖液中一般要加入表面活性劑（十二烷基磺酸鈉、tritonX-100等），使膜結(jié)構(gòu)破壞，利于蛋白質(zhì)與膜分離。在抽提過(guò)程中，應(yīng)注意溫度，避免劇烈攪拌等，以防止蛋白質(zhì)的變性。 2.3蛋白質(zhì)粗制品的獲得選用適當(dāng)?shù)姆椒▽⑺牡鞍踪|(zhì)與其它雜蛋白分離開(kāi)來(lái)。比較方便的有效方法是根據(jù)蛋白質(zhì)溶解度的差異進(jìn)行的分離。常用的有下列幾種方法： 1. 等電點(diǎn)沉淀法不同蛋白質(zhì)的等電點(diǎn)不同，可用等電點(diǎn)沉淀法使它們相互分離。 2. 鹽析法不同蛋白質(zhì)鹽析所需要的鹽飽和度不同，江蘇化學(xué)分析蛋白純化系統(tǒng)上門維修，所以可通過(guò)調(diào)節(jié)鹽濃度將目的蛋白沉淀析出。被鹽析沉淀下來(lái)的蛋白質(zhì)仍保持其天然性質(zhì)，并能再度溶解而不變性。 3，江蘇化學(xué)分析蛋白純化系統(tǒng)上門維修. 有機(jī)溶劑沉淀法中性有機(jī)溶劑如乙醇、**，它們的介電常數(shù)比水低，江蘇化學(xué)分析蛋白純化系統(tǒng)上門維修。能使大多數(shù)球狀蛋白質(zhì)在水溶液中的溶解度降低，進(jìn)而從溶液中沉淀出來(lái)，因此可用來(lái)沉淀蛋白質(zhì)。此外，有機(jī)溶劑會(huì)破壞蛋白質(zhì)表面的水化層，促使蛋白質(zhì)分子變得不穩(wěn)定而析出。由于有機(jī)溶劑會(huì)使蛋白質(zhì)變性，使用該法時(shí)，要注意在低溫下操作.江蘇化學(xué)分析蛋白純化系統(tǒng)上門維修</p><div

style="text-indent:25px">蛋白質(zhì)分離純化步驟蛋白質(zhì)分離純化的一般原則：大多數(shù)蛋白質(zhì)在組織細(xì)胞中都是和核酸等生物分子結(jié)合在一起，而且每種類型的細(xì)胞都含有成千上萬(wàn)種不同的蛋白質(zhì)。許多蛋白質(zhì)在結(jié)構(gòu)、性質(zhì)上有許多相似之處，所以蛋白質(zhì)的分離提純是一項(xiàng)復(fù)雜的工作。到目前為止，還沒(méi)有一**成的方法能把任何一種蛋白質(zhì)從復(fù)雜的混合物中提取出來(lái)。但是對(duì)于任何一種蛋白質(zhì)都有可能選擇一種較合適的分離純化程序以獲得高純度的制品。且分離的關(guān)鍵步驟、基本手段還是共同的。蛋白質(zhì)提純的目的是增加產(chǎn)品的純度和產(chǎn)量，同時(shí)又要保持和提高產(chǎn)品的生物活性。因此，要分離純化某一種蛋白質(zhì)，首先應(yīng)選擇一種含目的蛋白質(zhì)較豐富的材料。其次，應(yīng)設(shè)法避免蛋白質(zhì)變性，以制備有活性的蛋白質(zhì)。對(duì)于大多數(shù)蛋白質(zhì)來(lái)說(shuō)，純化操作都是在0～4℃的低溫下進(jìn)行的。同時(shí)也應(yīng)避免過(guò)酸、過(guò)堿的條件以及劇烈的攪拌和振蕩。另外，還要設(shè)法除去變性的蛋白質(zhì)和其它雜蛋白，從而達(dá)到增加純度和提高產(chǎn)量的目的。江蘇化學(xué)分析蛋白純化系統(tǒng)上門維修</p><div

蛋白質(zhì)純化方法-親和層析親和層析法包括特異性配體親和層析法以及通用性配體親和層析法。比較這兩種親和層析法。特異性配體親和層析法通常將復(fù)雜的生命大分子物質(zhì)作為配體，它的結(jié)合力比較大河吸附選擇性比較強(qiáng)。而通用性配體親和層析法通常將簡(jiǎn)單的小分子物質(zhì)作為配體，因此，它具有低廉的成本，吸附容量比較高，通過(guò)對(duì)吸附和脫附條件的改善能夠使得層析的分辨率提高。原理親和層析的原理類似于酶-底物，***-受體與抗原-抗體等特異性反應(yīng)的機(jī)理。有一定的親和力在每對(duì)反應(yīng)物之間。與在酶與底物的反應(yīng)中，只有特異的底物才可以結(jié)合一定的酶，使復(fù)合物產(chǎn)生相同。在親和層析中，只有特異的配體才可以和一定的生命大分子有親和力，并且使復(fù)合物產(chǎn)生。親和層析配體呈固相，而酶與底物的反應(yīng)底物呈液相是它們的不同點(diǎn)。事實(shí)上，親和層析是在含有活化基團(tuán)的基質(zhì)M上以共價(jià)鍵的方式固化具有識(shí)別能力的配體L，將固相載體制作成功而固化后的配體束縛特異物質(zhì)的能力依然保持。所以當(dāng)在小層析柱裝入固相載體，使得欲分離的樣品在該柱經(jīng)過(guò)。此時(shí)，樣品中對(duì)配體有親和力的物質(zhì)S就能夠通過(guò)結(jié)構(gòu)互補(bǔ)效應(yīng)、范德瓦爾力與靜電引力等作用在固相載體上吸附著。 </p><p style="text-indent:25px">蛋白質(zhì)分離純化步驟（二） 2.4.2 纖維素柱層析法該法是利用蛋白質(zhì)的酸堿性質(zhì)作為分離的基礎(chǔ)。離子交換纖維素（cellulose ion-exchanger）是人工合成的纖維素衍生物，它具有松散的親水性網(wǎng)狀結(jié)構(gòu)，有較大的表面積，使蛋白質(zhì)大分子可以自由通過(guò)。因此常用于蛋白質(zhì)的分離。（1）羧甲基纖維素（CM-纖維素）在纖維素顆粒上帶有羧甲基基團(tuán)。在中性pH條件下，羧甲基上的質(zhì)子可解離下來(lái)（圖2-27a），而溶液中帶正電荷的蛋白質(zhì)分子可與纖維素顆粒上的羧甲基負(fù)電荷結(jié)合?？山粨Q的基團(tuán)帶正電，因此是一種陽(yáng)離子交換劑。蛋白質(zhì)與離子交換纖維素之間結(jié)合能力的大小取決于彼此間相反電荷基團(tuán)之間靜電吸引。 (2）二乙氨基乙基纖維素（DEAE-纖維素）在中性pH條件下，它含有帶正電荷的基團(tuán)，可與溶液中的帶負(fù)電荷的蛋白質(zhì)結(jié)合，可交換的基團(tuán)帶負(fù)電荷，因此是一種陰離子交換劑。當(dāng)某一蛋白質(zhì)混合溶液通過(guò)裝有DEAE-纖維素的層析柱時(shí)，帶正電荷的蛋白質(zhì)不能結(jié)合而隨著洗脫液的流動(dòng)先被洗脫下來(lái)。帶負(fù)電荷的蛋白質(zhì)將被結(jié)合到柱上。結(jié)合力取決于彼此相反電荷基團(tuán)間的靜電吸引。然后選用一定pH和離子強(qiáng)度的緩沖液進(jìn)行洗脫，改變蛋白質(zhì)分子所帶的靜電荷，依次從層析柱流出達(dá)到相互分離的目的。</p><div

凝膠過(guò)濾法凝膠過(guò)濾法測(cè)定蛋白質(zhì)分子量的原理如“分離純化方法”中所述。一定型號(hào)的凝膠顆粒上具有一定大小的孔隙，只允許較小的分子進(jìn)入膠粒，而大于孔隙的分子則不能進(jìn)入膠粒而被排阻在膠粒外面。用洗脫液洗脫時(shí)，被排阻的分子量大的蛋白質(zhì)先被洗脫下來(lái)，隨后能夠進(jìn)入顆粒的蛋白質(zhì)也按分子量大小而先后被洗脫下來(lái)，分子量越小的越后被洗脫下來(lái)。由于不同排阻范圍的葡聚糖凝膠有一特定的蛋白質(zhì)分子量范圍，在此范圍內(nèi)，分子量的對(duì)數(shù)和洗脫體積之間成線性關(guān)系。因此，用幾種已知分子量的蛋白質(zhì)為標(biāo)準(zhǔn)進(jìn)行層析分析，以每種蛋白質(zhì)的洗脫體積對(duì)它們的分子量的對(duì)數(shù)作圖，繪制出標(biāo)準(zhǔn)洗脫曲線。未知蛋白質(zhì)在同樣的條件下進(jìn)行層析分析，根據(jù)其所用的洗脫體積，從標(biāo)準(zhǔn)洗脫曲線上可求出此未知蛋白質(zhì)對(duì)應(yīng)的分子量來(lái)。江蘇化學(xué)分析蛋白純化系統(tǒng)上門維修</p><p
