Thermo Scientific™ Pierce™ Copper Coated High Capacity Plates

Descrizione

Pierce Copper Coated Plates are ideal for analyzing 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. Although copper is less discriminating in its binding specificity than Nickel, the higher binding capacity of these plates is ideal for high throughput screening applications that need improved sensitivity and greater dynamic range.

Thermo Scientific Pierce Copper Coated High Binding Capacity (HBC) Plates use an exclusive coating process to increase the amount of histidine-tagged protein that will bind to the plate surface.

Features of Copper Coated High Binding Capacity Plates include:
• 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
• The detection limit is 0.1 pg of polyhistidine tagged fusion protein per well
• Pre-blocked for the ultimate convenience

Note: Copper coated plates are for use with purified His-tagged proteins. Typical cell lysates contain non-his-tagged proteins that may bind to copper, which can reduce binding capacity and signal-to-noise ratios. For cell lysates, use Thermo Scientific Pierce Nickel Coated Plates.
