Application Notes

Applications Validated by Active Motif:
WB*: 0.1 - 1 µg/ml

*Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western blot.

AbFlex® recombinant antibodies are genetically derived from DNA sequences of parental hybridoma clones. For details on the parental clone, see Catalog No. 39541.

Immunogen

This antibody was raised against a salt-extracted nuclear matrix preparation from MDCK (canine kidney) cells.

Buffer

Purified IgG in 140 mM Hepes, pH 7.5, 70 mM NaCl, 32 mM NaOAc, 0.035% sodium azide, 30% glycerol.

 

AbFlex® Nucleolin antibody (rAb) tested by Western Blot.
25 µg of HeLa cell nuclear extract (Lane 1) or 30 µg K562 cell nuclear extract (Lane 2) was run on SDS-PAGE and probed with AbFlex Nucleolin antibody at 0.5 µg/ml.

Background

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.

Storage

Some products may be shipped at room temperature. This will not affect their stability or performance. Avoid repeated freeze/thaw cycles by aliquoting items into single-use fractions for storage at -20°C for up to 2 years. Keep all reagents on ice when not in storage.
