Background
Cytokeratin 18 (CK18) is present in simple, glandular, and transitional epithelial cells, but is absent in stratified epithelial cells. CK18 usually multimerizes with Cytokeratin 8, and Anti-Cytokeratin 18 is useful for detecting adenocarcinomas of simple and glandular epithelium origin, as well as poorly differentiated squamous carcinoma cells.
Application
To ensure optimal assay performance, AREX recommends conducting reagent titration tailored to each testing system for optimal detection results.
*Results are sample-specific. Please refer to your local assay conditions and test parameters for reference.

FAQs
Are the pathology antibodies provided by AREX raw antibodies or ready-to-use solutions?
AREX Biosciences specializes in supplying high-quality IHC pathology raw antibodies (Raw Antibodies). We do not manufacture ready-to-use working solutions or IVD diagnostic reagents. We mainly provide concentrated raw materials to pathology reagent manufacturers and diagnostic platform companies to support product development and OEM production.
What development scenarios are pathology raw antibodies mainly used for?
Our raw antibodies are primarily used for the research, performance optimization, validation, and commercial-scale production of pathology IHC detection reagents. They are also suitable for companion diagnostics (CDx) projects and antibody screening.
How can I evaluate whether a raw antibody is suitable for our staining platform?
It is recommended to focus on specificity, sensitivity, background control, and performance on your target automated platforms (such as Roche Ventana, Leica Bond, Agilent Dako, etc.). We can provide internal test data for reference, but we recommend partners perform actual validation on their own platforms.
Can you provide samples for platform validation?
Yes. We can provide validation samples depending on the specific product. Some products may be provided free of charge, while others may involve a small sample fee. Handling fee and shipping fee will be charged separately. Please contact us for detailed confirmation.
How should raw antibodies be paired with detection systems?
AREX raw antibodies can be used with various polymer detection systems and ancillary reagents. We recommend optimization in combination with the ARExVisual® system or your existing detection platform to achieve better signal intensity and background control.
