General Notes
This product (Catalog No. DPABH-18292) is a rabbit-derived polyclonal antibody raised against human PSPC1, targeting the amino acid region 1–351 of the protein. This antibody exhibits cross-reactivity with Human PSPC1 from mouse and rat. It has been affinity purified by Protein A. PSPC1 (paraspeckle component 1), a known paraspeckle biomarker, is a putative transcription factor that belongs to the Drosophila behavior/human splicing (DBHS) family. PSPC1 was recently identified as a contextual determinant of tumor progression in multiple cancer types involving oncogenic reprogramming to switch proapoptotic TGF-β to prometastatic TGF-β via hijacking of Smad2/3 targeting. Upregulated PSPC1 is correlated with advanced tumor stages and poor survival of patients with breast, lung, and liver cancers. Upregulated PSPC1 potentiates expression of mesenchymal markers, EMT transcription factors (EMT-TF), cancer stem-like cell transcription factors (CSC-TF), and c-Myc-related proliferation genes, thus promoting migration, invasion, spheroid formation, tumor formation, and metastasis.
DPABH-18292 is suitable for use in Western blot (WB) (1:5,000–1:50,000), IP (0.5-4.0 μg for 1.0-3.0 mg of total protein lysate), IHC (1:250–1:1,000), IF/ICC (1:50–1:500) applications.
DPABH-18292 is supplied as a liquid formulation in PBS with 0.02% sodium azide and 50% glycerol, pH 7.3. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
