GWC highlights label-free arrays for proteins

The products are designed to work with the firm's SPRimager and SPRimagerII systems. SPR imaging systems use Surface Plasmon Resonance to detect molecular interactions on arrays without the use of fluorescent or other molecular labels.

Proteins are essential dietary components and have a significant effect on food quality. Protein foods are classified in two ways: complete and incomplete.

Complete proteins, which come from animal sources such as chicken, fish, dairy and soybeans, contain all the essential amino acids that help build muscle and body tissue while incomplete proteins, found in plant foods, such as grains, seeds, nuts, beans and vegetables, provide a varying but limited array of amino acids.

Scientists believe that a greater variety and amount of incomplete proteins must be consumed to cover all the amino acids needed for protein building.

SPR arrays facilitate simultaneous analysis of multiple samples under identical conditions in real time, allowing for robust experimental controls and rigorous comparisons of experimental samples. Glass SpotReady chips are coated with a hydrophobic background, and each chip has 16 or 25 gold spots in a grid pattern for probe attachment.

Each spot can be manually loaded with protein or other probes using the same pipettes employed for molecular biology and chemistry lab work. Chip surfaces are fully accessible, so users may select whatever surface chemistry is preferred for probe immobilisation.

GWC Technologies​ was established in 1990 and has established a strong presence within the American market. The group's head office is located in Taipei.

The company operates four factories, one in Taiwan and three in China.
