General Notes
This product (Catalog No. DPABH-05755) is a rabbit-derived polyclonal antibody raised against human PHAX, targeting the amino acid region 1–394 of the protein. It has been affinity purified by Protein A. Small nuclear and small nucleolar RNAs (snRNAs and snoRNAs) are essential components of snRNPs and snoRNPs, and have a critical role in the maturation of, respectively, mRNAs and rRNAs within the nucleus of eukaryotic cells. Complex and specific pathways exist for the assembly of snRNPs and snoRNPs, involving, nucleocytoplasmic transport of snRNAs and intranuclear transport between compartments of snoRNAs. In metazoa, a subset of spliceosomal snRNAs are exported from the nucleus after transcription. This export occurs in a large complex containing a snRNA, the nuclear cap binding complex (CBC), RanGTP, the leucine-rich nuclear export signal receptor CRM1/Xpo1, and the recently identified phosphoprotein PHAX (phosphorylated adaptor for RNA export). PHAX contains a conserved single-stranded nucleic acid binding domain (RNA_GG_bind domain) with no sequence homology with any other known RNA-binding module [PMID:15574332,11333016, 15574332].
DPABH-05755 is suitable for use in Western blot (WB) (1:500–1:3,000), IF/ICC (1:50–1:500) applications.
DPABH-05755 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.
