PTEN antibody | knockout validation | Cell Signaling 9556

This is a knockout-validated antibody summary, based on the publications "EGFR feedback-inhibition by Ran-binding protein 6 is disrupted in cancer", as cited below [1], "Targeted Deletion of PTEN in Kisspeptin Cells Results in Brain Region- and Sex-Specific Effects on Kisspeptin Expression and Gonadotropin Release" for immunohistochemistry knockout validation (see [2] figure 1b) and "Glioblastomas acquire myeloid-affiliated transcriptional programs via epigenetic immunoediting to elicit immune evasion" for western blot knockout validation (figure s1c) [3]. Labome curates formal publications to compile a list of antibodies with unambiguous specificity within Validated Antibody Database (VAD).
