Western blot analysis was performed on membrane enriched extracts (30 ug lysate) of A-549 (Lane 1), HEK 293 (Lane 2) and Mouse Brain (Lane 3). The blot was probed with Anti-Calreticulin Chicken Polyclonal Antibody (Product # PA1-902A, 1:500-1:2000 dilution) and detected by chemiluminescence using Goat anti-Chicken IgY (H+L) Secondary Antibody, HRP conjugate (Product # A16054, 0.4 ug/ml, 1:2500 dilution). A 48 kDa band corresponding to Calreticulin was observed across the cell lines and tissue tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 10 % Bis-Tris gel (Product # NP0302BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

PA1-902A detects calreticulin from canine, hamster, human, mouse and rat tissues.
PA1-902A has been successfully used in Western blot, immunocytochemistry and immunofluorescene procedures. By Western blot, this antibody detects an ~60-66 kDa protein representing calreticulin.
PA1-902A immunizing peptide corresponds to amino acid residues 24-43 from mouse calreticulin. PA1-902A immunizing peptide (Cat. # PEP-018) is available for use in neutralization and control experiments.
Calreticulin is the major calcium binding protein found in smooth muscle sarcoplasmic reticulum (SR) and non-muscle endoplasmic reticulum (ER) membranes. This protein was originally identified in SR membranes and plays a minor role in calcium storage in skeletal and cardiac muscle SR. Calreticulin is also known as calregulin, CRP55, CaBP3, calsequestrin-like protein and Ro/SS-A antigen. Calreticulin binds calcium with low affinity and high capacity, however it also exhibits a single high affinity binding site. The highly conserved sequence Lys-Asp-Glu-Leu (KDEL) is present at the C-terminus of calreticulin and other resident ER proteins including glucose regulated protein 78 (GRP78), GRP94 and protein disulfide isomerase (PDI). This sequence is responsible for the retention of newly synthesized proteins within the ER lumen. This retention is reported to be mediated by a KDEL receptor. Recent reports indicate that calreticulin can act as a modulator of the regulation of gene transcription by nuclear hormone receptors and may also act as a molecular chaperone.
