请大神前辈指点指点,已经研三了,实验很不顺利,再这样都要延期的节奏了。请问最近急性分离出来的大鼠心肌细胞很不耐钙,做膜片钳封接不上可能是什么原因造成的?谢谢了!
大概步骤如下:c57小鼠大概六七只,酒精浸泡后不处死取出,迅速打开胸腔取出心脏放入冰PBS冲洗。待心脏取出完毕,冲洗移入有PBS青霉素小瓶中用眼科剪剪成较小组织块。
之后加入0.1%胰酶消化(之前浓度为0.25%,活细胞数量更少。)吹打1min.放入孵箱中3min.弃去上清,加入∥型胶原酶(0.1%)吹打10Min,放入孵箱15Min。取出后加入1ml胰酶。吹打1Min后加入含血清F12培养液终止消化,800转离心5Min。之后取沉淀重悬种板。90Min差速贴壁法纯化心肌细胞。
48h后只有少量(个位数)细胞贴壁,呈三角形。
第一次用0.25%胰酶时离心后有大量鼻涕样物质。
第二次胰酶浓度减小后没有,但细胞沉淀少,且为半透明微白。是不是离心时间不够。
感觉细胞整体状态都不好,几次都没有大量心肌细胞,更不用说观察到心肌细胞搏动。
老师们能不能帮忙分析一下是哪里的原因呢。
有没有比较稳定的小鼠乳鼠心肌细胞分离步骤呢。
希望大神快点出现。
想用二步酶消法来分离毛乳头细胞,一个毛囊大概有多少个毛乳头细胞?处于生长期的毛囊在显微镜下有什么特点?先谢谢大神们指点
前辈们好,近期老板布置任务需要分离小鼠肝脏细胞,查了好多文献,都没有写胶原酶的cat#,只写sigma订购,想请教下,是否有人做过,可以提供下货号和使用方法吗?十分感谢。另外,文中还提到digitonin,如果有一起用到的话麻烦帮我查看下,谢谢。
各位师兄师姐:
我近期负责的课题,需要进行人类血液淋巴细胞和DC细胞的分离和培养,但我在方面懂的不多,想求助这方面的大神们。后续我需要做RT-qPCR,western-blot、免疫荧光等实验,我应该去多少ml全血比较好?全血怎么保存?怎么进行分离?后续怎么培养和保存?
谢谢!
我做的临床试验,就想简单检测PBMC细胞的凋亡,上流式检测,有啥检测效果好的步骤推荐一下,谢谢
经过无数次的大鼠肝脏插针灌注,忍受过实验结果不理想的打击和折磨,今天终于成功了,特分享些相关图片以鼓励还在奋战中的网友们。
我的步骤:
1、16-22天小鼠颈椎脱臼法处死后,75%酒精浸泡30秒消毒,睾丸取出后置预冷PBS,40分钟(路上所需时间)后开始处理。
2、剔除白膜,剪碎睾丸。0.25%胰酶(含edta)1.5ml/个睾丸37°C消化30-50分钟,等体积DMEM/F12含10%FBS终止消化,1000r/MIN离心5分钟,弃上液。
3、加0.1%胶原酶消化30分钟,过200目网筛,1000r/MIN离心5分钟,弃上液。
4、DMEM/F12含10%FBS5ml重悬后转如培养瓶,入孵育箱37°C5%CO2培养。
请教各位,我到底是哪里有问题,是胰酶消化的时间长了吗?
