Copper coated microlates 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. These copper-coated plates are available in clear that can be used with colorimetric methods.
- For quantitating previously undetectable histidine-tagged proteins
- 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
