Data Examples
Intracellular Staining by Flow Cytometry
Detection of Calreticulin in HeLa Human Cell Line by Flow Cytometry. HeLa human cervical epithelial carcinoma cell line was stained with Mouse Anti-Human Calreticulin PE‑conjugated Monoclonal Antibody (Catalog # IC3898P, filled histogram) or isotype control antibody (Catalog # IC0041P, open histogram). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Background: Calreticulin
Human Calreticulin is a 55‑60 kDa, 400 amino acid (aa), variably glycosylated intra- and extracellular Ca++-binding lectin that is ubiquitously expressed. It consists of three domains: a 180 aa N-terminal globular region, a 111 aa P-, or proline rich domain, and a 109 aa C-terminus. The 180 aa N-terminus (aa 18‑197) is termed Vasostatin. It is unclear if it is ever generated naturally via proteolytic processing. The Vasostatin domain has many functions. It binds to RNA (aa 18‑27), has autocatalytic phosphorylase activity (aa 77‑197), binds to a KxFFKR motif on steroid hormone receptors, and serves as a lectin-type chaperone for ER-localized molecules. It also shows antiangiogenic activity, presumably by binding to laminin carbohydrates and blocking endothelial cell adhesion and proliferation. Human Calreticulin is 94% aa identical to mouse and rat Calreticulin.
