Anti-Calreticulin antibodies are essential reagents in flow cytometry for detecting the protein encoded by the CALR gene. Calreticulin is a calcium-binding chaperone that promotes folding, oligomeric assembly, and quality control in the endoplasmic reticulum. It is found in the cytosol, ER lumen, cytolytic granule, and can also be secreted. Examine the supplier's provided validation data when comparing Calreticulin antibodies for flow cytometry. Also look for application-specific recommendations, such as dilutions, protocols, sample types, and other helpful usage notes.
