    or cell culture pellets
  • Custom-sized and configured arrays are constructed using the Beecher MTA-I
  • Tissue core sizes can range from 0.6 mm to 2.0 mm, providing from 40 to over 200 sample cores in one
    paraffin block
  • Microarray slides can be stained using a variety of histochemical or immunohistochemical reactions

Laser Capture Microdissection

Laser Capture Microdissection microscopic image

  • Zeiss PALM Microbeam LCM
  • Capable of isolating cells, tissues, or stromal matrix from either frozen and paraffin sections
  • Ideal method to insure the purity of the starting material for downstream proteomic and genomic applications
  • Capable of operating on an RNAse free level to insure high quality samples for genomic studies

Archival FFPE Human Tissue Samples

Archival FFPE Human Tissue Bank image

  • Archival collection consisting of over 40 years of surgical pathology FFPE specimens
  • Searchable database enables the investigator to locate specific patient, tissue or tumor types
  • Ability to collaborate with anatomic pathologists to assist in the identification and selection of study samples along with the interpretation and scoring of results
  • Perfect for use as control tissues, study samples or TMA sources
  • Capable of isolating DNA or RNA from samples
