  • Relevance

    RBM14 is a RNA-binding protein. These proteins contribute to gene expression by regulating the form, abundance and stability of both coding and non-coding RNAs. In vertebrates, RNA binding proteins can also influence many processes involved in RNA processing, for example, activity-dependent transcript localization and localized protein synthesis amongst others.

  • Detection of Human CoAA by Western Blot.

    Samples: Nuclear extract (NE) from HeLa cells.

    Antibody: ab12325 used at 0.3 mcg/ml. Detection: Chemiluminescence with an exposure time of 30 seconds.

  • ICC/IF image of ab12325 stained MCF7 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab12325, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Customer reviews and Q&As


Thank you for your enquiry. The epitope recognized by ab12325 maps to a region between residues 150 and 200 of human Coactivator Activator (RNA Binding Motif Protein 14) using the numbering given in entry NP_006319.1 (GeneID 10432). Unfortunately, I cannot provide the exact sequencing as this is proprietary. I hope this information will be useful. Should you require any further assistance, please do not hesitate to contact me.
