Anti-SRPX Antibody

SRPX (Sushi Repeat Containing Protein, X-linked) is a secreted glycoprotein implicated in cell adhesion, extracellular matrix interactions, and neurodevelopment, with altered expression reported in several solid tumor types. This rabbit polyclonal antibody from Antibodies.com recognizes the human SRPX protein in its unconjugated form and is validated for Western blot and immunohistochemistry workflows on relevant research samples. Supplied as a 100 µl aliquot, the reagent provides enough material for multiple membrane incubations or tissue-section staining runs and is raised against epitopes of human SRPX, making it a useful tool for studying expression across cell lysates and fixed tissue sections. Researchers investigating tumor invasion pathways, angiogenesis-related signaling, or X-linked neurodevelopmental disorders use this reagent to probe SRPX localization and abundance. The polyclonal format offers broader epitope coverage than monoclonal alternatives, which can be helpful when working with post-translationally modified or alternatively spliced variants of the target protein. For sample preparation, lysates can be prepared in standard RIPA buffer for immunoblotting, while paraformaldehyde-fixed, paraffin-embedded sections are commonly used for IHC detection in expression-mapping studies.
