Introducing our bioinformatics solutions.
Cell Type Reference Database
version 1.0
A knowledgebase of manually collected, curated and annotated cell types in multiple species. CellKb allows users to search through published cell type signatures from selected single-cell and bulk RNA-seq experiments.
CellKb v1.0 contains 18,985 signatures of 1,072 cell types from 10 species extracted from 316 publications.
Protein-protein interactions with reliability scores
version 9.0
An open-source database of experimentally identified protein-protein interactions collected from literature with reliability scores assigned based on the annotations of the interacting proteins. The first version of HitPredict was released in 2005.
HitPredict v9.0 contains 753,103 protein-protein interactions between 87,977 proteins from 124 species.
