Tissue Microarrays


ProteoGenex provides custom-built Tissue Microarrays (TMAs) for target expression and biomarker analysis in diseased, normal adjacent, and normal tissues. Tissue Microarrays can be used to validate clinical relevance of potential biological targets in the development of diagnostics, therapeutics, and in studying new protein markers and genes. The use of TMAs offers an alternative quality control method for research and non-research purposes.

ProteoGenex constructs TMA using carefully selected donors' tissues. Detailed tissue localization in each TMA block is recorded precisely.

ProteoGenex provides TMA of the following cancer tissue types:


  • Breast
  • Colon / Rectum
  • Lung
  • Stomach
  • Head&Neck
  • Kidney
  • Thyroid
  • Ovary
  • Prostate
  • Bladder
  • Melanoma
  • Lymphoma
  • Metastatic tissues

ProteoGenex can prepare TMA blocks from FFPE tissue samples with >5 years follow-up information.

TMAs Features

  • FFPE human tissues
  • Core sizes 0.6 - 2 mm
  • Up to 400 cores per case
  • TMA map
  • H&E images for each 10th slide supported by clinical information and path reports

Complete patient confidentiality must be ensured at all times.
