Use DoubletFinder to remove double cells in single cell data

Single Cell RNA Sequencing (scRNA-seq) can reveal the heterogeneity of gene expression in single cells. However, this technique faces a common problem, that is, the interference of doublets. Double cells are mixtures of RNA from two or more different cells, the presence of which can lead to inaccurate interpretation of gene expression. Therefore, we can use the DoubletFinder suite to remove these double cells to obtain more accurate and cleaner scRNA-seq data.

6 cell type annotation databases - a good helper for querying cell types!

The kit for automatic identification of cells can only be used for preliminary identification of cell types. If you want to further confirm the cell type, you need to rely on the knowledge and experience of the researcher for judgment. The following are some commonly used cell marker databases for single-cell data analysis. The methods of use are very simple. You only need to input the name of the characteristic gene, and you can find the possible corresponding cells from the database for your reference.
