2025
This video demonstrates a method to detect the Cyanobacterial strains in an environmental sample using an antibody microarray chip. Samples carrying various bacteria interact with printed antibodies, and immunostaining with fluorophore-labeled anti-cyanobacterial-strain antibodies reveals the presence of specific cyanobacterial strains through fluorescence in distinct spots.

Expression Profiling with Microarrays

2023
Microarrays are important tools for profiling gene expression, and are based on complementary binding between probes that are attached to glass chips and nucleic acids derived from samples. Using these arrays, scientists can simultaneously evaluate the expression of thousands of genes. In addition, the expression profiles of different cells or tissue types can be compared, allowing researchers to deduce how the expression of different genes change during biological processes, and thus gain...

Tissue microarrays allows for an efficient method to gain concurrent information from a multitude of tissues. Representative parts of tissues are assembled into a single paraffin block. Sections from the block are used for immunohistochemistry and analysis of protein expression patterns. Digital scanning generates corresponding images for distribution of data.

FAQs
A mapped grid links every recipient-block position to the corresponding donor specimen. This positional record allows researchers to interpret staining or hybridization results according to the original sample rather than treating the cores as anonymous tissue. Maintaining that identity is essential when comparing biomarkers, disease features, or treatment responses across many specimens.
Precise placement ensures that each core occupies a known location within the recipient block, while the small cylindrical format conserves valuable donor tissue. Together, these features support inclusion of many selected specimens in one organized block and make their results easier to compare under consistent experimental conditions.
Cores from multiple donor specimens are processed together after they are arranged in the recipient block. Because the samples undergo embedding, sectioning, mounting, and downstream analysis in a shared format, researchers can evaluate them under consistent experimental conditions. This design supports parallel assessment rather than relying on separate specimen-by-specimen workflows.
The technique concentrates selected tissue cores from many donor specimens into a single recipient block, whereas separate examination keeps specimens in individual preparations. The consolidated format reduces use of valuable samples and enables parallel analysis. It is therefore suited to studies that need consistent comparison of biomarkers, disease characteristics, or responses to treatment.
The cores are arranged in a mapped grid and embedded within the recipient block. The block is then sectioned, and the resulting tissue sections are mounted on slides for analysis. This sequence converts the organized three-dimensional arrangement of samples into slide-based preparations while preserving the positional information needed for interpretation.
Prepared sections can support immunohistochemistry, which evaluates tissue features through antibody-based staining, and in situ hybridization, which analyzes targets within their tissue location. The same organized sample format can also support other assays. These applications allow investigators to examine biological markers across many specimens using a coordinated experimental design.
It is particularly useful when a study must compare many specimens for biomarker patterns, disease features, or treatment responses while conserving limited tissue. By placing selected cores into one recipient block, investigators can analyze a broad specimen set in parallel and maintain a clear connection between each observed result and its source tissue.
