Stains and Applications

From routine applications to more complicated procedures, Inotiv has the expertise and the capability to determine the ideal specialty stain for your research needs. Our talented histotechnicians continuously create the highest quality novel stains that highlight what you need to move your program forward.


Image Analysis, TEM, and Quantitative Microscopy

At Inotiv, you’ll benefit from industry-recognized expertise in Image Analysis (IA). Consultation and design-based techniques, coupled with broad histochemical/immunohistochemical capabilities and knowledge of disease, ensure we deliver the best and most efficient quantitative evaluations possible to accelerate your development project.

We offer:

  • Computer assisted, high-throughput capability
  • Artificial Intelligence (AI) applied across multiple platforms, including Visiomorph™, Visiopharm®, inForm® and HALO®
  • Stereology
    • Unbiased, design-based, using statistically proven principles
    • Multiple platforms, including newCAST™
  • Conducted on brightfield whole slide scanned images (Aperio AT2) or IF imaged slides (Vectra® Polaris™)
  • HALO® and Visiopharm® image analysis platforms allow analysis of IHC and ISH with modular expansion to include H-scoring of membrane expressed tumor targets and spatial distancing
  • Multiplex IHC analysis
  • Cell proximity evaluation
  • Multiplex IF analysis conducted with inForm or Visiopharm platforms
  • Transmission electronic microscopy (TEM) is considered the gold standard for determining several important diagnoses such as:
    • Phospholipidosis 
    • Identification of immune deposits in the renal glomerulus
    • Endoplasmic reticulum stress
    • Neuroendocrine cell identification and more
  • Quantitative microscopy provides you with high-quality data for applications such as:
    • Muscle fiber cross-sectional area and Feret’s diameter
    • Co-expression of markers; double-stain positivity in the cytoplasm or nucleus
    • Area and area ratios; volume and volume ratios (e.g., volume of infarcted tissue, collagen, or mucus in an organ)
    • Membrane marker quantitation
    • Immune cells in tumors
    • Object quantitation (e.g., microvessels, amyloid plaque, glomeruli, islets)
    • Number of cells in a structure or organ
    • Microglial activation
    • Layer thickness
    • Proliferation assays
  • Reporting — pathologist oversight of prepared illustrative images and interpretive reports

Whole Slide Scanning

Our team creates beautiful, extremely high-resolution whole slide images up to 40x magnification, which then can be seamlessly quantified using Visiopharm® or HALO® image analysis software to distribute data to you.

Our capabilities include:

  • Whole slide brightfield and fluorescence scanning of H&E, IHC, IF, ISH, and special stains
  • Diagnostic quality, high through-put resolution images up to 40x preserved digitally
  • Zoom in and out, pan around the scanned slide just like a microscope
  • Images are compatible with several third-party image-analysis providers
  • Whole slide images can be returned via hard drive, DVD, or reviewed online
  • Simple, secure online access from any web browser, on any computer
  • Evaluate scanned slides, organized by study, all in one place


Immunohistochemistry (IHC) and Immunofluorescence (IF)

At Inotiv, we are committed to providing you with exceptional immunohistochemistry (IHC) and immunofluorescence lab services. Our extensive expertise with advanced techniques across a wide array of disease models allows us to produce IHC and IF staining that research and discovery organizations rely on for accurate assessments of their preclinical programs. Our ability to provide specialized approaches to your complex needs, while still maintaining quick turnaround times and high quality, makes Inotiv your partner of choice with the ideal source for reliable IHC and IF lab services.

Here’s how we can support you:

  • Method development
  • New antibody protocol optimization
  • Custom antibody panels
  • Immunophenotyping markers
  • Variety of cell type specific markers across multiple species
  • Transduced proteins and tags
  • Bone and other specialty tissues
  • Paraffin and frozen sections
  • Staining for Bright field and fluorescence microscopy
  • Antibody validation
  • Project specific R&D
  • Automated quantification of IHC including Nuclear, Membrane, Cytoplasm, and CD markers

Inotiv can help with other aspects of your project, such as method or protocol development and rushed completion requirements.


In Situ Hybridization (ISH)

We offer the ISH technique to bring you faster and more accurate results when quantifying your nucleic acid targets across tissues and cell lines.

This includes:

  • Custom-made probes to identify specific gene expression and miRNA, lncRNA, and viral DNA genomes
  • Frequently used as an adjunct to assess IHC validity
  • Multiplex staining
    • ISH combined with IHC capabilities
    • Multiplex FISH
