也就是进行除法:Feature_UMI_counts/all_UMI_count,每一个基因的表达被表示为单个基因mRNA数占所有mRNA数的比例,然后乘以一个scale.factor,这个参数匹配的应该设定是Cellranger计算后的average_UMI_per_Cell,系统默认10000,在10X技术的合理范围内。这一步比较简单,再看看后面的scaledata,功能是Scales and centers ...
如下是旧的sc.pp.normalize_per_cell()警告。 官方对于使用旧版sc.pp.normalize_per_cell函数的警告 最大的区别用人话来说,就是它不会自动给你过滤了,原来这个函数默认旧把min_counts<1的基因给去除了,实际上许多时候也无伤大雅,但是有时我们并不像这个潜在的var过滤发生,所以在新版的sc.pp.normalize_total()...
其实最近在Nature Biotechnology上发表的一篇名为"Bayesian inference of gene expression states from single-cell RNA-seq data"的文章,里面介绍的"sanity"标准化处理数据取得的效果更佳,但是目前学习资源有限,本人尚未找到运行"sanity"的方法,若有意与本人交流单细胞测序学习心得的,可私信一起讨论学习。

Aliquots of the dilution curves were added to the cell plate in a volume of 50 μL per well resulting in final assay concentrations ranging from 1 × 10−14 to 1 × 10−7 M. The assay plate was incubated for 3 h at 37 °C and 5% CO2. After the incubation, the assay plate ...
Mannose is a natural bioactive monosaccharide that binds specifically to mannose receptors (CD206) on the cell surface and exhibits anti-inflammatory as well as anti-oxidative activities [15,52]. CD206 has been established as a marker of M2 macrophages, but less is characterized regarding its fun...
