HTAP uses iLabs for all services. For instructions on how to create an account and log-in, visit the iLabs instruction page.

Histology and Pathology Services

Request Services: Register in iLab and submit request


  • Tissue/Cell processing and embedding
  • Unstained tissue array sectioning
  • H&E -staining
  • Special stains including: PAS, ORO, Trichrome, VVG for elastin, Giemsa
  • Sectioning of thick tissue curls for RNA/DNA isolations

Immunohistochemistry (IHC)

Request Services: Register in iLab and submit request


  • IHC using core or researcher provided primary antibodies
  • Double antibody IHC
  • BrdU staining
  • Apoptosis/TUNEL assay

Laser Capture

Request Services: Register in iLab and submit request


Laser capture microdissection with the Arcturus XT instruments is a way for researchers to isolate a particular type of cell or a group of cells with very little contamination. This allows DNA and RNA to be isolated from the cells. The service or amplification of the RNA and/or DNA after isolation is also offered. Tissue samples can be submitted as frozen or paraffin sections.

Image Analysis

Request Services: Register in iLab and submit request


HTAP can provide state of the art image analysis of standard sections or tissue microarrays using inForm Software. Sections can be stained with standard stains, IHC stains, or immunofluorescence stains. inForm can be trained to find virtually any tissue type, structure, or tissue subtype. Moreover, inForm can provide area object counts or be used to automatically assess IHC staining levels on a cell-by-cell and sub-cellular basis, providing extremely accurate and sensitive quantitation.

  • Digital imaging of stained slides
  • Digital Scoring of IHC and TUNEL slides
  • Image Analysis using Inform and Vectra

Pathology Consultation

Request Services: Register in iLab and submit request

One of our experienced pathologists will schedule time to review your slides with you.

Archive Tissue Microarray (TMA)

Request Tissue Microarray Services: E-mail request to Daniel G. Rosen, M.D.


HTAP manages an archive that contains formalin fixed paraffin-embedded tissue specimens from a variety of organ/disease types. Approximately 10 to 12 years of clinical, pathological and follow-up data is available for most of these tissue specimens. TMA's can be produced using the core's archived collection and/or researcher provided tissue.

  • Identify the cases that meet investigator's project need.
  • Investigator's can choose from a library of existing TMAs which include normal and cancer tissues that are site specific or from a multi-tissue array.
  • TMA or cell array can be built using specimens provided by the investigator.
  • Alternatively, a TMA can be designed to address specific questions in the investigator's proposed research.
  • Clinical & pathological data that is associated to each specimen on the array is displayed in the design in an excel format.
  • TMA quality control: Tissue/cell type and diagnosis for each specimen on TMA is confirmed by a pathologist.

Tissue Acquisition and Distribution

Supported by the Dan L. Duncan Cancer Center, human tissue banking activities have been expanded to include development of a uniform consent and standardized tissue collection process across all tumor sites at the Michael E. DeBakey Veteran's Affairs Hospital and Ben Taub Hospital.


  • Project-based tissue collection
  • Tissue acquisition in support of clinical trials and research protocols
  • Inventory and data management

Request Tissue

Please include the following with your electronic form submission:

  1. Completed request form
  2. A summary of your request
  3. An IRB Protocol or IRB exemption letter

Note: All three of these should be attached as one PDF document and emailed to Michael M. Ittmann, M.D., Ph.D.
