HCMI TPM dataset

We have added 591 models and 298 tumors from the Human Cancer Models Initiative (HCMI) into our Celligner visualization, using RNA-seq TPM quantifications from NCI’s Genomic Data Commons (GDC).

Olink Proteomics dataset

We have profiled 161 cell lines covering 24 different cell line lineages using the Olink Explore HT platform. To learn more about Olink, please visit their website here.

Sanger Proteomics dataset

We’ve included a matrix of relative protein quantities from Gonçalves et al. 2022. The original data was downloaded from Cell Model Passports.
