植物原生質(zhì)體制備試劑盒                                        

●  產(chǎn)品組成：

● 產(chǎn)品簡(jiǎn)介：

植物原生質(zhì)體是指脫去全部細胞壁由質(zhì)膜包被的具有生命活力的裸露細胞。它具有細胞生命特征和全能型，是細胞無(wú)性系變異和突變體篩選的重要來(lái)源，同時(shí)也是植物遺傳工程的理想受體和遺傳改良的理想材料。酶解法分離原生質(zhì)體是一個(gè)常用的技術(shù)，其原理是植物細胞壁主要由纖維素、半纖維素和果膠質(zhì)組成，因而使用纖維素酶、半纖維素酶、離析酶和果膠酶能降解細胞壁成分，去除細胞壁，即可得到原生質(zhì)體。試劑盒配套的酶混合物是纖維素酶R-10和離析酶R-10的混合物，優(yōu)化的酶配比能很好地消化植物細胞壁，提取到良好的植物原生質(zhì)體。

按照每次使用5 ml酶消化體系計算，本試劑盒可用于20次酶消化反應。本試劑盒每個(gè)5 ml反應體系可處理0.1 g左右的擬南芥葉片(約10~15葉片)，操作較好的情況下每5 ml體系可獲得約50-70萬(wàn)個(gè)原生質(zhì)體(不同植物不同操作會(huì )有一定的差異)，可滿(mǎn)足約25-70個(gè)樣品的原生質(zhì)體質(zhì)粒轉染操作(按照每樣1-2萬(wàn)個(gè)細胞計算)。

本試劑盒不含有原生質(zhì)體轉化試劑，需要轉化請參見(jiàn)植物原生質(zhì)體轉化試劑盒（RTU4092 ）。

● 貯存、效期及運輸：

  按照標簽溫度保存，至少一年有效。-20℃貯存組分4℃存放3-4不會(huì )影響使用效果。3-4天經(jīng)常使用的情況，可以全部保存在4℃。

試劑盒常溫運輸。

● 使用說(shuō)明：

   需要準備的材料（試劑盒不提供）：

   平頭鑷子；一次性刀片；50 ml離心管；1.5 ml離心管；水浴鍋

一、原生質(zhì)體分離：

即用型酶溶液配制

注：溶液I容易被微生物污染，使用時(shí)須嚴格按照無(wú)菌操作規范進(jìn)行或者適當分裝后使用。

55℃處理能滅活核酸酶和蛋白酶并促進(jìn)酶的溶解；

即用型酶溶液現用現配，不建議配制后凍存后再使用；

溶解好的正常酶溶液應為澄清棕黃色溶液，如使用純度不好的酶，溶液為不溶解的乳白色懸濁液，不能使用。

1. 酶解：

取生長(cháng)狀態(tài)良好的葉片切成0.5-1 mm的小條，按照0.1 克葉片（擬南芥約15-20個(gè)葉片）加5 ml即用型酶溶液的比例迅速將切割好的葉片小條浸泡于酶溶液中，避光，無(wú)需震蕩，常溫（20-25℃）酶解3小時(shí)，間歇混勻。

注：酶解時(shí)間與葉片種類(lèi)，葉片生長(cháng)狀態(tài)有關(guān)，請根據實(shí)驗需要適當調整酶解時(shí)間。3小時(shí)為擬南芥葉片推薦的酶解時(shí)間。如條件允許，可以使用微型真空泵常溫避光條件下抽真空30 min，以使酶溶液更好地進(jìn)入細胞間隙。酶溶液變?yōu)榫G色表明有原生質(zhì)體已經(jīng)有分離，溶液為濃綠色表明原生質(zhì)體已經(jīng)大量分離。擬南芥原生質(zhì)體大小約為30-50 μm，顯微鏡鏡檢后確定是否分離。葉片原生質(zhì)體細胞顯微鏡下為綠色圓球狀，葉綠體分散在整個(gè)細胞內，說(shuō)明狀態(tài)較好；如呈現不規則形狀，說(shuō)明原生質(zhì)

體破碎或即將破碎。

 2. 漂洗：

        取適量溶液II-漂洗溶液（5×），用超純水稀釋為1×漂洗溶液。

酶解后加入等體積的1×漂洗溶液，如使用5 ml酶解體系，加入5 ml 1×漂洗溶液，輕柔混勻。

3. 過(guò)濾：

用孔徑70 μm篩網(wǎng)過(guò)濾步驟2中的溶液，去除未消化的葉片，用5-10 ml 1×漂洗溶液沖洗酶解器皿和未消化的葉片1-2次，將所有的液體收到50 ml離心管中。

4. 第一次收集：

濾出液100g常溫離心 2分鐘，盡量去除上清。

注：為了避免原生質(zhì)體離心時(shí)貼在管壁，建議整個(gè)實(shí)驗過(guò)程使用水平轉頭；離心時(shí)，可調低離心機的升速和降速。升速過(guò)快，原生質(zhì)體可能離到管壁上；降速過(guò)快，可能導致管底原生質(zhì)體懸起。建議升速和降速分別都使用3。

5. 第二次收集：

加入2-5 ml 1×漂洗溶液，用剪尖的藍吸頭重懸原生質(zhì)體，冰浴30分鐘，原生質(zhì)體在重力

作用下可以沉降到離心管底部，盡量吸除上清，收集原生質(zhì)體。(如果發(fā)現原生質(zhì)體沉降的速度比較慢或者得率比較低，也可以考慮常溫100 g離心1-2 min收集原生質(zhì)體)。

6. 重懸：

小心去除上清溶液，不要觸動(dòng)原生質(zhì)體沉淀，沉淀用剪尖的藍吸頭重懸于1 ml溶液III中即為原生質(zhì)體溶液。（可以用血球計數板計數，根據原生質(zhì)體數量調整溶液III的加入體積，使得原生質(zhì)體密度為2×10⁵/ml或更高）。

注：制備好的原生質(zhì)體可以在4oC或冰浴保存至少24 h。

二、實(shí)驗示例：

                使用植物原生質(zhì)體制備試劑盒轉染擬南芥原生質(zhì)體的效果圖。

實(shí)驗步驟：稱(chēng)取0.48 g轉化試劑于2 ml 離心管中，加入轉化試劑溶解液后，顛倒混勻，蒸餾水定容至2 ml，使轉化試劑充分溶解后備用。在2 ml的圓底離心管中加入10 μl（20 μg）EGFP質(zhì)粒 (植物用綠色熒光蛋白)，加入100 μl制備好的原生質(zhì)體，輕柔混勻后加入110 μl當日配制好的轉化試劑溶液，輕柔混勻，常溫靜置5 min后加入440 μl 1×漂洗溶液終止轉化，輕輕顛倒混勻，常溫100 g離心1 min，去除上清，再加入0.5 ml 1×漂洗溶液，輕柔重懸原生質(zhì)體，常溫100 g離心1 min后，盡量去除上清，收集原生質(zhì)體。加入1 ml溶液V，小心重懸原生質(zhì)體后水平放置25℃培養過(guò)夜(約16h)，次日于熒光顯微鏡下檢測EGFP熒光信號。
