Monoclonal antibody that recognizes a domain on heterogeneous nuclear ribonucleoprotein K and PTB-associated splicing factor

Abstract

hnRNP K protein is a member of the heterogeneous nuclear protein (hnRNP) complex that, besides its function as a translational regulator of human mRNA, is also considered to be a transcription factor involved in tumorigenesis. PSF is a protein part of the human spliceosome and essential in RNA splicing. Here we report the generation of one monoclonal antibody GG6H9.1C3 that recognized both hnRNP K and PSF proteins using Western blot analysis, flow cytometry, and immunocytochemistry.
