Advantages of biomarker discovery using ProtoArray® technology

This high-content discovery tool provides sensitive and reproducible results, quickly and easily (Figure 1). Only ProtoArray® microarrays provide immediate protein identification and involve:

  • As little as 10 microliters of sera or plasma
  • No pre-labeling or tagging
  • Simple profiling protocol for biomarker discovery

ProtoArray® Human Protein Microarrays have been successfully used to identify biomarkers from a number of different diseases. Examples included identifying cancer biomarkers for ovarian [1], prostate [2], bladder [3], and lung cancers [4]. The arrays have also been successfully used to identify non-HLA protein biomarkers in transplantation patients [5-7].

The ProtoArray® Immune Response Biomarker Profiling application is available either as a custom service or as a product.
