Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts. 


This Copine I antibody was raised against a peptide corresponding to amino acids 519-532 of human Copine I.


Rabbit serum containing 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.


Copine I antibody (pAb) tested by Western blot.

Copine I pAb tested by Western blot.
Detection of Copine I by Western blot analysis. 20 µg of PC-3 whole-cell extract probed with Copine I pAb at a 1:2,000 dilution.


Copine I (CPNE1) is a member of a family of calcium phospholipid-binding proteins that play a role in cell signaling. Copine I augments the activated Tumor Necrosis Factor-alpha (TNF-α) signaling pathway in a calcium-dependent manner. Copine I is a repressor protein that physically interacts with NFκB p65 to inhibit NFκB-mediated transcription.

Positive Control

Active Motif's PC-3 nuclear extract (Catalog No. 36082) can be used as a positive control for Copine I antibody.


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
