Pierce Copper coated plates are ideal for analysing polyhistidine-tagged fusion proteins by ELISA-based methods. Proteins that contain a succession of several histidine residues at the amino or carboxyl terminus have a strong binding affinity for metals such as copper.

• Quantitate previously undetectable histidine-tagged proteins
• Wider dynamic range with four-fold greater capacity than regular nickel chelate-coated plate
• Copper chelate provides greater binding capacity than nickel
• Detection limit is 0,1 pg of polyhistidine tagged fusion protein per well
• Pre-blocked for the ultimate convenience

These high binding capacity plates use an exclusive coating process to increase the amount of histidine-tagged protein that will bind to the plate surface.

Surface treatment: Divalent copper, metal chelate
Plate blocking: Blocker™ BSA buffer
