In situ Hybridization

  • Chromogenic in situ hybridization
  • Hybridization performed on a DakoCytomation Slide Hybridizer

Tissue Microarray

  • Tissue microarrays can be created with any combination of human tissue, animal tissues or cell culture pellets
  • 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

DNA Extraction

  • DNA extraction from formalin-fixed paraffin embedded (FFPE) tissue sections suitable for PCR
Laser Capture Microdissection

The MMPRCL now has laser capture microdissection available located in C7718 using the Zeiss PALM Microbeam. With this instrument an experienced investigator is capable of isolating individual cell, tissues, or stromal matrix from either frozen and paraffin sections. It is an ideal method to insure the purity of the starting material for downstream proteomic and genomic applications in the common situation where analyses of whole tissue homogenates will yield imprecise results due to the heterogeneity of tissue or cell types. The lab is capable of operating on an RNAse free level to insure high quality samples for genomic studies.
