Background
Actin is part of the cytoskeletal system of every cell type. It can be classified based on isoelectric points as alpha, beta, and gamma. Muscle Specific Actin includes those of the alpha and gamma isotypes. Skeletal, smooth, and cardiac muscle cells will all stain positively with Anti-Muscle Specific Actin, but mesenchymal cells, not including myoepithelium, will stain negatively. Normal and neoplastic non-muscle cells, including vascular endothelial and connective tissues, carcinomas, melanomas, and lymphomas, will also be negative for muscle specific actin. The use of Anti-Muscle Specific Actin in concert with Anti-Smooth Muscle Actin can allow for differentiation between rhabdomyosarcoma and leiomyosarcoma, as muscle specific actin is found in rhabdomyoblasts, while smooth muscle actin is found in leiomyosarcomas.
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.
