Based on sequence analysis, ab200835 (PCBP2/hnRNP E2) shares 80% homology with family member PCBP1. The levels of XR were tested in the accompanying blocking experiment.

This data was developed using ab200835, the same antibody clone in a different buffer formulation.Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HeLa (Human epithelial cells from cervix adenocarcinoma) cells labeling PCBP2/hnRNP E2 with ab200835 at 1/500 dilution, followed by Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/500 dilution (green). Nuclear and cytoplasmic staining on HeLa cell line is observed. The nuclear counter stain is DAPI (blue). Tubulin is detected with ab7291 (anti-Tubulin mouse mAb) at 1/1000 dilution and ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution (red).
The negative controls are as follows;
-ve control 1: ab200835 at 1/500 dilution followed by ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution.
-ve control 2: ab7291 (anti-Tubulin mouse mAb) at 1/1000 dilution followed by ab150077 (Alexa Fluor®488 Goat Anti-Rabbit IgG H&L) at 1/500 dilution.

Goat anti rabbit IgG (FITC) at 1/150 dilution was used as the secondary antibody.

This data was developed using ab200835, the same antibody clone in a different buffer formulation.PCBP2/hnRNP E2 was immunoprecipitated from 1mg of Jurkat (Human T cell leukemia cells from peripheral blood) whole cell lysate with ab200835 at 1/80 dilution. Western blot was performed from the immunoprecipitate using ab200835 at 1/1000 dilution. Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1500 dilution.Lane 1: Jurkat whole cell lysate 10 µg (Input). Lane 2: ab200835 IP in Jurkat whole cell lysate. Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab200835 in Jurkat whole cell lysate.
