BioIVT’s Tissue Microarrays (TMAs) provide our customer with a screening tool representing multiple donors. TMAs can be used to discover new protein or genetic markers and are efficient research tools for diagnostic development and validation. Tissue arrays can also be used to measure protein, RNA or DNA markers, and are compatible with immunohistochemistry (IHC) staining and potentially in situ hybridization (ISH). Standard human derived TMAs of tumor and normal samples are available for research studies (from FFPE or Frozen tissue). Products are available both as sections as well as whole block. Custom TMAs are available upon request.

All specimens are collected using consented donors under IRB approval and are pre-reviewed by a board certified pathologist to confirm tissue type and diagnosis

Our high-density, high-quality oncology and normal tissue FFPE microarrays are currently available in three standard formats:

  • Focused Oncology Array representing over 120 cases (360 0.6mm cores) of breast, prostate, lung and colon cancer with representative normal tissue from each organ
  • Normal Array representing a FDA panel of 36 normal tissues from 3 donors (324 0.6mm cores)
  • Broad Oncology Array representing 12 different tumor types with associated normal controls with 72 unique samples (144 1.0mm cores)

In addition, the following TMAs are available:

  • Lung Fibrosis Array representing IPF (9), PF (4) and normal (4) lung samples, with 34 cores
  • Frozen FDA Array representing 36 FDA/EMA cross-reactivity tissues arranged across three separate frozen arrays, each containing 12 non-diseased human tissues in duplicate, from three donors (72 1.5mm cores)
  • Custom designed microarrays are available through our PHASEZERO® services
