W16007B_PURE_IRF5_Antibody_1_081920
Whole cell extracts (15 µg protein) from C2C12 (reduced expression control), RAW264.7 (positive control), and THP-1 (mouse reactivity control) cells were resolved on a 4-12% Bis-Tris gel, transferred to PVDF and probed with 0.1 µg/mL (1:5000 dilution) of purified anti-IRF5 antibody (clone W16007B) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-rat IgG antibody (Cat. No. 405405) at a 1:3000 dilution. Direct-Blot™ HRP anti-β-actin antibody (Cat. No. 643807) was used as a loading control at a 1:20000 dilution (lower). Lane M: Molecular weight marker.

    C57BL/6 mouse splenocytes were fixed, permeabilized, and then stained with purified anti-mouse IRF5 antibody (clone W16007B) (left) or purified rat IgG2a, κ isotype control (right) followed by polyclonal goat anti-rat IgG secondary antibody PE. Cells were then washed and stained with anti-mouse/human B220 APC.
  • W16007B_PURE_IRF5_Antibody_3_081920
    Whole cell extracts (250 µg total protein) prepared from RAW264.7 cells were immunoprecipitated overnight with 2.5 µg of purified rat IgG2a, κ isotype ctrl antibody (Cat. No. 400502) or purified anti-IRF5 antibody (clone W16007B). The resulting IP fractions and whole cell extract input (6%) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with clone W16007B.

Description

The interferon regulatory factor (IRF) family of transcription factors comprises nine members with conserved domains. IRF5 mediates the induction of proinflammatory cytokine, such as IL-6 and TNFa. IRF5 is highly expressed in monocytes, macrophages, B cells, and dendritic cells. Expression of IRF5 is associated with many autoimmune diseases.

Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.05 - 0.1 µg/mL. For intracellular flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µL volume. For immunoprecipitation, the suggested use of this reagent is 2.5 µg/test. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This clone was tested for ICC using RAW264.7 cells fixed with 4% PFA and permeabilized with either Triton X-100 or methanol. While both methods were compatible with IRF5 staining, the signal was weak and did not meet our sensitivity standards.

This clone does not recognize human IRF5. For detection of human IRF5, please use BioLegend clone 11F4A09 (Cat. No. 652602).

During product development testing of this clone for western blot, a ~37 kD protein of unknown origin was faintly detected. This protein may represent a minor IRF5 degradation product.
