固相内毒素清除剂100g价格的详细介绍:



实验步骤:

1.从少量样品(1-10mg组织或102-104细胞)中提取RNA时可加入少许糖原以促进RNA沉淀。例如加800ml TRIzol匀浆样品,沉淀RNA前加5-10μg RNase-free糖原。糖原会与RNA一同沉淀出来,糖原浓度不高于4mg/ml是不影响一链的合成,也不影响PCR反应。

2.匀浆后加之前样品可以在-60至-70℃保存至少一个月。RNA沉淀可以保存于75% 酒精中2-8℃一星期以上或-5至-20℃一年以上。

3.分层和RNA沉淀时也可使用台式离心机,2600×g离心30-60分钟。

固相内毒素清除剂100g价格操作步骤:

1. 匀浆处理:a.组织 将组织在液氮中磨碎,每50-100mg组织加入1ml TRIzol,用匀浆仪进行匀浆处理。样品体积不应超过TRIzol体积10℅。

b.单层培养细胞 直接在培养板中加入TRIzol裂解细胞,每10cm2面积(即3.5cm直径的培养板)加1ml,用移液器吸打几次。TRIzol的用量应根据培养板面积而定,不取决于细胞数。TRIzol加量不足可能导致提取的RNA有DNA污染。

c.细胞悬液 离心收集细胞,每5-10×106动物、植物、酵母细胞或1×107细菌细胞加入1ml TRIzol,反复吸打。加TRIzol之前不要洗涤细胞以免mRNA降解。一些酵母和细菌细胞需用匀浆仪处理。

2.将匀浆样品在室温(15-30℃)放置5分钟,使核酸蛋白复合物完全分离。

3.可选步骤:如样品中含有较多蛋白质,脂肪,多糖或胞外物质(肌肉,植物结节部分等)可于2-8℃10000×g离心10分钟,取上清。离心得到的沉淀中包括细胞外膜,多糖,高分子量DNA,上清中含有RNA。处理脂肪组织时,上层有大量油脂应去除。取澄清的匀浆液进行下一步操作。

5. 每使用1ml TRIzol加入0.2ml,剧烈振荡15秒,室温放置3分钟。

6. 2-8℃10000×g离心15分钟。样品分为三层:底层为黄色有机相,上层为无色水相和一个中间层。RNA主要在水相中,水相体积约为所用TRIzol试剂的60℅。

7. 把水相转移到新管中,如要分离DNA和蛋白质可保留有机相,进一步操作见后。用异丙醇沉淀水相中的RNA。每使用1ml TRIzol加入0.5ml异丙醇,室温放置10分钟。

8. 2-8℃10000×g离心10分钟,离心前看不出RNA沉淀,离心后在管侧和管底出现胶状沉淀。移去上清。

9. 用75℅乙醇洗涤RNA沉淀。每使用1ml TRIzol至少加1ml 75℅乙醇。2-8℃不超过7500×g离心5分钟,弃上清。

10.室温放置干燥或真空抽干RNA沉淀,大约晾5-10分钟即可.不要真空离心干燥,过于干燥会导致RNA的溶解性大大降低。加入25-200μl无RNase的水或0.5℅SDS,用枪头吸打几次,55-60℃放置10分钟使RNA溶解.如RNA用于酶切反应,勿使用SDS溶液。RNA也可用100℅的去离子甲酰胺溶解,-70℃保存。

产品介绍 C4orf22 is a 233 amino acid protein that exists as three alternatively spliced isoforms and are encoded by a gene encoding maping to human chromosome 4, which represents approximately 6% of the human genome and contains nearly 900 genes. Notably, the Huntingtin gene, which is found to encode an expanded glutamine tract in cases of Huntington's disease, is on chromosome 4. FGFR-3 is also encoded by a gene that maps to chromosome 4 and has been associated with thanatophoric dwarfism, achondroplasia, Muenke syndrome and bladder cancer. Chromosome 4 is also tied to Ellis-van Creveld syndrome, methylmalonic acidemia and polycystic kidney disease.

产品介绍 Representing approximately 6% of the human genome, chromosome 4 contains nearly 900 genes. Notably, the Huntingtin gene, which is found to encode an expanded glutamine tract in cases of Huntington's disease, is on chromosome 4. FGFR-3 is also encoded on chromosome 4 and has been associated with thanatophoric dwarfism, achondroplasia, Muenke syndrome and bladder cancer. Chromosome 4 is also tied to Ellis-van Creveld syndrome, methylmalonic acidemia and polycystic kidney disease. Chromosome 4 reportedly contains the largest gene deserts (regions of the genome with no protein encoding genes) and has one of the two lowest recombination frequencies of the human chromosomes. The C4orf14 gene product has been provisionally designated C4orf14 pending further characterization.
