● 產(chǎn)品簡介:
植物原生質(zhì)體是指脫去全部細(xì)胞壁由質(zhì)膜包被的具有生命活力的裸露細(xì)胞。它具有細(xì)胞生命特征和全能型,是細(xì)胞無性系變異和突變體篩選的重要來源,同時也是植物遺傳工程的理想受體和遺傳改良的理想材料。植物原生質(zhì)體轉(zhuǎn)化試劑盒(Plant Protoplasts Transformation Kit)采用的是聚乙二醇轉(zhuǎn)化方法,借助聚乙二醇短時間內(nèi)對原生質(zhì)體產(chǎn)生的沖擊效應(yīng),使質(zhì)粒DNA、RNA或蛋白得以進(jìn)入原生質(zhì)體,經(jīng)轉(zhuǎn)化的植物原生質(zhì)體經(jīng)過一定時間培養(yǎng)后,可用于檢測外源基因的表達(dá)和功能,轉(zhuǎn)化后基因敲除或基因編輯效果等。
對于擬南芥原生質(zhì)體,使用本試劑盒轉(zhuǎn)化質(zhì)粒后通常2-6小時可以檢測相關(guān)基因的轉(zhuǎn)錄變化(mRNA等RNA的變化),通常2-16小時后可以檢測到相關(guān)蛋白表達(dá)的變化,通常24小時可以檢測到基因編輯的效果。
本試劑盒可以用于相當(dāng)于6孔板40個孔的樣品,12孔板20個孔的樣品,或24孔板40個孔的樣品的轉(zhuǎn)化。
本試劑盒不含有原生質(zhì)體制備試劑,需要制備原生質(zhì)體請參見植物原生質(zhì)體制備試劑盒(RTU4082 )。
● 貯存和效期:
按照溫度貯存,有效期一年。轉(zhuǎn)化試劑現(xiàn)用現(xiàn)配。
試劑盒常溫運(yùn)輸。
● 使用說明:
需要準(zhǔn)備的材料(試劑盒不提供):
平頭鑷子;一次性刀片;50ml離心管;1.5ml離心管;水浴鍋
一、原生質(zhì)體轉(zhuǎn)化步驟:
1. 轉(zhuǎn)化溶液配制:
植物原生質(zhì)體轉(zhuǎn)化參考下表根據(jù)樣品量配制轉(zhuǎn)化溶液。
轉(zhuǎn)化溶液現(xiàn)用現(xiàn)配。轉(zhuǎn)化溶液需要在轉(zhuǎn)化前至少1小時配制,以確保轉(zhuǎn)化試劑溶解充分。轉(zhuǎn)化溶液配制后盡量當(dāng)天使用。配制好的轉(zhuǎn)化溶液4℃保存3-5天之內(nèi)仍然有較好的轉(zhuǎn)化效率,但和當(dāng)天配制的轉(zhuǎn)化溶液相比,轉(zhuǎn)化效果可能會有一定程度的下降。

2. 準(zhǔn)備質(zhì)粒:
取10 μl質(zhì)粒DNA(10-20
μg,濃度為1-2 μg/μl)于1.5 ml 離心管中。
注:質(zhì)粒大小建議為5-10
kb,質(zhì)粒濃度為1-2 μg/μl左右;原生質(zhì)體轉(zhuǎn)化對于質(zhì)粒的純度要求較高,盡量使用高純度的質(zhì)粒。多個質(zhì)粒同時轉(zhuǎn)化時的體積和總質(zhì)量保持不變。多個質(zhì)粒轉(zhuǎn)化時,每種質(zhì)粒的用量比例,需要酌情自行調(diào)整。質(zhì)粒轉(zhuǎn)化也可以在12或24孔板中進(jìn)行,轉(zhuǎn)化體系也可以按照比例放大或縮小。本試劑盒中描述的用量相當(dāng)于是6孔板中的用量。原生質(zhì)體用多孔板培養(yǎng)時,最好選擇未經(jīng)表面處理的多孔板。對于經(jīng)過表面處理的動物細(xì)胞培養(yǎng)用多孔板,可以使用5%胎牛血清或小牛血清處理孔表面數(shù)秒,這樣有助于減小孔底表面對于原生質(zhì)體的損傷。
3. 質(zhì)粒轉(zhuǎn)化:
3.1 質(zhì)粒管中加入100 μl原生質(zhì)體溶液(原生質(zhì)體密度為2×105/ml,約2萬個原生質(zhì)體),輕柔混勻。
3.2 加入等體積即110 μl 步驟1事先準(zhǔn)備好的轉(zhuǎn)化溶液,輕彈管底,輕柔混勻,常溫25℃放置5-15分鐘。
注:最長可以孵育15 min,但通常孵育5min時間已經(jīng)足夠。最佳的孵育時間對于不同的原生質(zhì)體和不同的質(zhì)粒需要通過實(shí)驗(yàn)摸索。
4. 終止轉(zhuǎn)化:
加入2倍體積轉(zhuǎn)化終止溶液即440 μl,輕柔徹底混勻,終止轉(zhuǎn)化過程。
5. 收集原生質(zhì)體:
常溫100g離心1-2分鐘,盡量去除上清。
注:由于轉(zhuǎn)化后的溶液會非常粘稠,加入轉(zhuǎn)化終止溶液后離心1 min通??梢允乖|(zhì)體聚集在管底,但使用某些突變體時為減少原生質(zhì)體損失,可將離心時間延長到2 min。為了避免原生質(zhì)體離心時貼在管壁,建議整個實(shí)驗(yàn)過程使用水平轉(zhuǎn)頭;離心時,可調(diào)低離心機(jī)的升速和降速。升速過快,原生質(zhì)體可能離到管壁上;降速過快,可能導(dǎo)致管底原生質(zhì)體懸起。建議升速和降速分別都使用3。
6. 原生質(zhì)體漂洗:
加入500 μl 轉(zhuǎn)化終止溶液輕輕重懸原生質(zhì)體,常溫100g離心1 min,盡量去除殘留的上清。
注:本步驟可以充分去除殘留的轉(zhuǎn)化試劑溶液中的組分,避免轉(zhuǎn)化試劑溶液中的組分對于后續(xù)的不良影響。
7. 原生質(zhì)體重懸:
沉淀中加入1
ml培養(yǎng)溶液,輕柔重懸。
8. 原生質(zhì)體培養(yǎng):
將離心管水平放置,23-25oC弱光培養(yǎng)。
注:根據(jù)實(shí)驗(yàn)需求確定孵育時間。RNA分析孵育2-6小時;酶活性分析和蛋白標(biāo)記實(shí)驗(yàn)孵育2-16小時;基因編輯的效果在轉(zhuǎn)化24小時后可能被檢測到。

實(shí)驗(yàn)步驟:稱取0.48
g轉(zhuǎn)化試劑于2 ml 離心管中,加入轉(zhuǎn)化試劑溶解液后,顛倒混勻,蒸餾水定容至2 ml,使轉(zhuǎn)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(dāng)日配制好的轉(zhuǎn)化試劑溶液,輕柔混勻,常溫靜置5
min后加入440 μl轉(zhuǎn)化終止溶液終止轉(zhuǎn)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 轉(zhuǎn)化終止溶液,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培養(yǎng)溶液,小心重懸原生質(zhì)體后水平放置25℃培養(yǎng)過夜(約16h),次日于熒光顯微鏡下檢測EGFP熒光信號。
