Anti-PSCA Antibody

This rabbit polyclonal antibody from Antibodies.com targets Prostate Stem Cell Antigen (PSCA), a GPI-anchored cell-surface glycoprotein expressed on normal prostate epithelium and frequently re-expressed in prostate, bladder, pancreatic, and gastric carcinomas. The unconjugated reagent is supplied as 100 µl of liquid and is validated for Western blot and immunohistochemistry workflows on human samples, supporting research into prostate cancer progression, urothelial tumor profiling, and immunohistochemical characterization of solid-tumor tissue microarrays. As a polyclonal reagent raised in rabbit, it recognizes multiple epitopes across the PSCA extracellular domain, enabling detection in denatured lysates and fixed paraffin-embedded sections alike. Investigators studying tumor stem-cell markers, lineage tracing in prostate tissue, or biomarker discovery in genitourinary cancers can use this reagent for both qualitative IHC staining and protein-level confirmation by Western blot. Storage at 2 to 8 degrees C with brief handling on wet ice preserves activity through routine use, and the small pack size suits pilot studies or screening of limited clinical cohorts where antibody consumption must be conserved.
