What is a Tissue Microarray?
A tissue microarray is a paraffin-embedded block containing an array of core samples from healthy and diseased tissue, for use as a positive and negative control. Multiple core samples can be arrayed on a standard paraffin block.
What can I use a Tissue Microarray for?
TMAs are especially useful in immunohistochemistry, where specificity of external controls can be validated on a single slide. Other uses for TMAs include in-situ hybridization, PCR, and routine histochemistry stain validation.
What kind of TMAs do you offer?
Using canine or feline tissue, we can create a custom TMA to meet the needs of your project. Customizable options include tissue diameter, number of tissue samples, species, organ type, and more.
Which special stain controls do you offer?
In addition to tissue microarrays, we offer positive controls for many common special stains, including; Gram, PAS, Silver, Copper, Movat’s Pentachrome, Sirius Red and Trichrome staining.
FFPE control blocks, as well as pre-cut control slides are available. Please contact us for more information.
