AbFlex® Nucleolin antibody (rAb), sample
AbFlex antibodies are recombinant antibodies (rAbs) that have been generated using defined DNA sequences to produce highly specific, reproducible antibodies. Each AbFlex antibody contains a 6xHis Tag, a Biotinylation Tag for enzymatic biotin conjugation using the biotin ligase, BirA, and a sortase recognition motif (LPXTG) to attach a variety of labels directly to the antibody including fluorophores, enzymatic substrates (HRP, AP), peptides, drugs as well as solid supports. AbFlex Nucleolin antibody was expressed as full-length IgG with mouse immunoglobulin heavy and light chains (IgG2a isotype) in mammalian 293 cells. Nucleolin (NCL, C23) is an abundant and ubiquitously expressed protein that is a major component of the nucleolus. Nucleolin seems to be overexpressed in highly proliferative cells and is involved in many aspects of gene expression: chromatin remodeling, DNA recombination and replication, RNA transcription by RNA polymerase I and II (RNA pol II), rRNA processing, mRNA stabilization, cytokinesis and apoptosis. Its role as a histone chaperone has recently been identified. It is involved in the synthesis and maturation of ribosomes, and is located mainly in dense fibrillar regions of the nucleolus.
