Options available depend on the customer's needs and the type of testing required

  • Technical Staining Only - IHC and IF Testing

Immunohistochemistry stains are used to detect the presence, amount and localization of specific proteins to aid in determining neoplasms. It is also used to provide prognostic information.

We offer an extensive list of antibodies and profiles for the diagnosis of poorly differentiated tumors, identity of primary and metastatic tumors, and classification of lymphomas which provide pathologists and oncologists with the information needed to offer patients the best treatment and therapy for their cancer.

Immunochemistry (IHC) 

Direct immunofluorescence staining is used to diagnose diseases of the skin, kidney, heart and other organ systems using a fluorescent dye such as fluorescein isothiocyanate.

Immunofluorescence (IF)

In-Situ Hybridization uses labeled complementary nucleic acid to target specific nucleic acids in a tissue or cells to indicate the presence of a gene.

We offer FISH and CISH to isolate and identify genetic alterations in solid tumor and hematological neoplasms.

We offer a wide menu of antibodies for testing which can be ordered individually or as panels.
