Detection of Calreticulin-2 in MCF‑7 Human Cell Line by Flow Cytometry. MCF‑7 human breast cancer cell line was stained with Mouse Anti-Human Calreticulin‑2 Monoclonal Antibody (Catalog # MAB2927, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Calreticulin-2 is a soluble lectin-like molecule that participates in the protein folding and quality control cycle in the endoplasmic reticulum (ER) lumen. Mature human Calreticulin-2 has a 178 amino acid N-terminal globular domain, a 97 aa central P-domain, and a 90 aa C-terminal domain. The globular domain shows lectin activity, the P-domain binds one Ca++ ion with high affinity, and the C-terminus binds Ca++ and contains an RNEL ER retention motif. The amino acid sequence of Calreticulin‑2 is 84%, 83% and 87% identical to that of mouse, bovine and canine Calreticulin‑2, respectively.
