Biomarker Colocalization Imaging Analysis
Tissue biomarkers are playing an increasing role in scientific research, disease diagnosis and treatment response prediction. The scope of histology or tissue biomarker identification can range from conventional histochemistry (such as H&E) to nucleic acid (ie, DNA, RNA) and protein detection. Although traditional histochemical staining is still the most widely used method, immunohistochemistry (IHC) has become the most commonly used technique for the specific detection of tissue biomarkers.

Biomarker Colocalization Imaging Analysis
The combination of immunohistochemistry (IHC) and fluorescence microscope provides an important and widely used tool for researchers and pathologists to image and analyze a variety of biomarkers in tissue samples. Researchers and pathologists of CD BioSciences determine the range and changes of cell populations by immunohistochemistry, and check the presence of indicated receptors and markers in diseases, so as to evaluate the effects of drug treatment on animal and human tissues.

Biomarker Colocalization Imaging Analysis Workflow
The following is the general process of biomarker colocalization imaging analysis:
Step 1
Sample preparation
Tissue samples are transferred to PBS w/0.05% azide or made into FFPE, OCT compounds.
Step 2
Sample staining
Use immunohistochemical techniques to process, section, and stain samples.
Step 3
Imaging
The sample slide is imaged under a high-throughput slide scanner.
Step 4
Analyze
Analyze the images according to customer requirements.
Step 5
Send data
Send images and quantitative reports to customers.
Delivery
Whole slide images in RGB format
Statistical analysis
Other relevant data
Data tables containing cell counts or area for biomarkers
Histograms of spatial distribution for nearest neighbor analysis
