style="text-indent:25px">三、蛋白質(zhì)分子量的測(cè)定蛋白質(zhì)分子量測(cè)定的方法很多，目前常用的方法有以下幾種。 3.1 凝膠過濾法凝膠過濾法測(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，化學(xué)分析蛋白純化系統(tǒng)。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，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，分子量越小的越后被洗脫下來。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，化學(xué)分析蛋白純化系統(tǒng)，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，化學(xué)分析蛋白純化系統(tǒng)，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?；瘜W(xué)分析蛋白純化系統(tǒng)</p><div

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。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（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。可交換的基團(tuán)帶正電，因此是一種陽離子交換劑。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。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><p

凝膠過濾層析凝膠過濾層析（gel-filtration chromatography）又稱為分子排阻層析或分子篩層析。它是將葡聚糖凝膠（Sephadex）裝入一個(gè)柱子中，制成凝膠柱。這種凝膠顆粒具有網(wǎng)狀結(jié)構(gòu)，不同類型凝膠的網(wǎng)孔大小不同。當(dāng)把蛋白質(zhì)混合樣品加到凝膠柱中時(shí)，比凝膠網(wǎng)孔小的蛋白質(zhì)可進(jìn)入網(wǎng)孔內(nèi)，而大于網(wǎng)孔的分子則不能進(jìn)入被排阻在凝膠顆粒之外。當(dāng)用洗脫液洗脫時(shí)，被排阻的分子量大的蛋白質(zhì)直接通過凝膠之間的縫隙先被洗脫下來，而比網(wǎng)孔小的蛋白質(zhì)可連續(xù)不斷地進(jìn)入網(wǎng)孔內(nèi)。這樣的小分子不但流經(jīng)的路程長(zhǎng)，而且受到來自凝膠內(nèi)部的阻力也很大，所以蛋白質(zhì)越小，從柱子上洗脫下來所需時(shí)間越長(zhǎng)。由于不同蛋白質(zhì)的分子大小不同，進(jìn)入網(wǎng)孔的程度不同，因此流出的速度不同，洗脫所用體積及時(shí)間不同，從而達(dá)到分離的目的。山東專業(yè)蛋白純化系統(tǒng)制造廠家</p><p
