Background
S100 is a 21kDa highly acidic and water soluble protein, which is expressed in a wide variety of normal and neoplastic cells of mesodermal, neuroectodermal, and epithelial origin. The protein is a dimer, having two subunits, alpha and beta, with extensive sequence homology. There are 3 forms of S-100 protein: alpha-alpha, known as S-100A0; alpha-beta, known as S-100A and beta-beta, known as S-100B. The immunohistochemical evaluation of S-100 (beta) protein expression is important in the diagnosis of undifferentiated malignant tumours of unknown primary origin and should be included in the so-called primary panel. S100 is a very sensitive marker for malignant melanoma of all types. S100 may be used in the differential diagnosis of sarcomas and spindle cell tumours.
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.
