General Notes
This product (Catalog No. DPABH-12051) is a rabbit-derived IgG polyclonal antibody raised against human PSPC1. This antibody exhibits cross-reactivity with PSPC1 from mouse and rat. It has been affinity purified by protein A. This gene encodes a nucleolar protein that localizes to punctate subnuclear structures that occur close to splicing speckles, known as paraspeckles. These paraspeckles are composed of RNA-protein structures that include a non-coding RNA, NEAT1/Men epsilon/beta, and the Drosophila Behavior Human Splicing family of proteins, which include the product of this gene and the P54NRB/NONO and PSF/SFPQ proteins. Paraspeckles may function in the control of gene expression via an RNA nuclear retention mechanism. The protein encoded by this gene is found in paraspeckles in transcriptionally active cells, but it localizes to unique cap structures at the nucleolar periphery when RNA polymerase II transcription is inhibited, or during telophase. Alternative splicing of this gene results in multiple transcript variants. A related pseudogene, which is also located on chromosome 13, has been identified.
DPABH-12051 is suitable for use in Western blot (WB) (1:2,000–1:5,000), IHC (1:50–1:200) applications.
DPABH-12051 is supplied as a liquid formulation in PBS with 0.02% sodium azide, 50% glycerol, pH7.3. 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.
