使用權(quán)限 A類培養(yǎng)需要滿足以下條件
1、無(wú)菌、無(wú)毒的環(huán)境:首先應(yīng)保證被培養(yǎng)的細(xì)胞處于無(wú)菌、無(wú)毒的環(huán)境,即對(duì)培養(yǎng)液和所有的培養(yǎng)用具進(jìn)行無(wú)菌處理。通常還要在培養(yǎng)液中添加一定量的抗生素以防培養(yǎng)過(guò)程中的污染。
2、營(yíng)養(yǎng)物質(zhì):細(xì)胞體外培養(yǎng)所需營(yíng)養(yǎng)物質(zhì)與體內(nèi)基本相同,需要有葡萄糖、氨基酸、促生長(zhǎng)因子、無(wú)機(jī)鹽、微量元素等。通常還需加入血清、血漿等一些天然成分。
3、溫度和pH:細(xì)胞體外培養(yǎng)的適宜溫度一般與動(dòng)物的體溫相近。多數(shù)細(xì)胞生存的適宜pH為7.2~7.4。
4、氣體環(huán)境:培養(yǎng)所需氣體主要有O2和CO2,O2是細(xì)胞代謝所必需的,CO2的主要作用是維持培養(yǎng)液的pH。進(jìn)行細(xì)胞培養(yǎng)時(shí),通常采用培養(yǎng)皿或松蓋培養(yǎng)瓶,將其置于含95%空氣加5% CO2的混合氣體的培養(yǎng)箱中進(jìn)行培養(yǎng)。
操作步驟:
1. 將無(wú)菌的蓋玻片置于細(xì)胞培養(yǎng)皿中,將細(xì)胞懸液接種于培養(yǎng)皿中進(jìn)行細(xì)胞爬片,待細(xì)胞長(zhǎng)至80%時(shí)取出爬片。
2. 用PBS浸洗爬片3次,4%的多聚甲醛固定爬片15min,再次用PBS浸洗玻片3次,每次3min。
3. 0.5% Triton X-100(PBS配制)室溫孵育爬片20min,使細(xì)胞通透。
4. 3% H2O2滴加爬片上以阻斷內(nèi)源性過(guò)氧化物酶,室溫孵育15min(一般用甲醇或蒸餾水稀釋30%過(guò)氧化氫),PBS沖洗3次,每次3min。
5. 封閉血清室溫孵育20min,PBS沖洗3次,每次3min。
6. 細(xì)胞特異性一抗孵育:按照抗體說(shuō)明書(shū)稀釋比例稀釋好一抗,滴加在爬片上,于4°C濕盒中孵育一夜,PBS沖洗3次,每次3min。
7. 二抗孵育:選與一抗對(duì)應(yīng)的二抗,按比例稀釋后滴加在爬片上,37°C濕盒中孵育30min,PBS沖洗3次,每次3min。
8. 將爬片周圍水漬吸干,爬片上滴加新鮮配制的DAB顯色液,顯微鏡下觀察,當(dāng)出現(xiàn)棕黃色或棕褐色的陽(yáng)性信號(hào)時(shí)用蒸餾水沖洗終止顯色。
9. 復(fù)染:用Harris蘇木素復(fù)染30s~1min,水洗后用1%的鹽酸酒精分化,再用蒸餾水(或PBS)水洗返藍(lán)。
10. 封片:將中性樹(shù)膠滴在爬片一側(cè),再用蓋玻片蓋上,先放平蓋玻片一側(cè)再輕輕放下另一側(cè),以免產(chǎn)生氣泡,封好的爬片平放置于通風(fēng)廚中晾干。
11. 鏡檢觀察。

中文名稱:CDI活化瓊脂糖
英文名字:CDI Amine Reactie Agarose
說(shuō)明:
CDI Amine Reactie Agarose consists of 6% cross-linked agarose actiated with CDI (1,1’-carbonyl diimidazole) to form reactie imidazole carbamates. The actiation of the resin occurs in solent and to maintain its actiity. The resin is supplied in acetone to preent hydrolysis. Upon reaction of the resin with primary amine containing molecules, i.e. proteins, in basic (pH8.5~10) aqueous buffers, the imidazole carbamates lose the imidazole group and form carbamate linkages. CDI Amine Reactie Agarose is ideal for immobilizing peptides, small organic molecules and certain proteins and reactions can occur in organic solent making it ideal for water-insoluble ligands.Features:Proen coupling chemistry, Easy to use, no secondary coupling agents required, Stable linkages, Couple in inorganic buffers for insoluble molecules. Suitable for Couple proteins and peptides. Couple primary amine containing ligands.

中文名稱:Con A瓊脂糖
英文名字:Concanaalin A (Con A) Agarose
特點(diǎn):
Binds α-D-mannopyranosyl, α-D-glucopyranosyl and sterically related residues. Purification or enrichment of glycoproteins, polysaccharides and glycolipids. Ligand Density:10~16 mg Con A/ml resin. Capacity:20~50 mg thyroglobulin/ml resin. Bead structure:4% agarose. For purification/ enrichment of glycoproteins, polysaccharides and glycolipids.
說(shuō)明:
Concanaalin A (Con A) Agarose consists of Con A coupled to 4% agarose by the cyanogen bromide method. Con A is a tetrameric metalloprotein lectin isolated from Canaalia ensiformis (jack bean). Con A is used for the purification of glycoproteins, polysaccharides and glycolipids as it binds molecules containing α- D-mannopyranosyl, α-D-glucopyranosyl and sterically related residues. Con A agarose has also be used in other application areas including purification of enzyme-antibody conjugates, purification of IgM and separation of membrane esicles. As stated aboe, Con A is a metalloprotein and to maintain its binding characteristics the presence of both Mn2+ and Ca2+ is essential. Each subunit of Con A utilizes one calcium and one manganese ion and these cations can be remoed under acidic conditions abolishing the carbohydrate-binding actiity.
