Protein expression Microarray

Creative BioMart has a high throughput protein microarray technique that enables measurements of protein expression levels in hundreds of biological samples. Proteins extracted from cell lysates, bio-fluids or fixed-tissues are immobilized as spots in rows on a solid support. Each micro-spot holds the entire proteome of a sample. Highly specific antibodies are used to simultaneously screen these spots for the level of distinct target proteins.


  • High throughput method using automation
  • Microvolumes of sample (5-10 µl)
  • Convenient cost

Key advantages against Western Blot analyses:
