In the version of this article initially published, in the Methods section “In vitro phagocytosis assay”, the clone number for the anti-SIPRPα blocking antibody was incorrectly given as OSE-172. The correct nomenclature for this antibody is “humanized blocking anti-SIRPα clone 18D5”. The error has been corrected in the HTML and PDF versions of the article.
