Applications for beta-Actin Antibody

Recommended Usage



Simple Western


Western Blot

Application Notes
This antibody is useful for Western Blot. A 40 kDa band is detected in HeLa whole cell lysate and mouse NIH3T3 cells. For IHC, epitope retrieval with citrate buffer pH6.0 is recommended for FFPE tissue sections.

In Simple Western only 10 - 15 uL of the recommended dilution is used per data point. Separated by Size-Wes, Sally Sue/Peggy Sue.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: beta-Actin

Actin is a highly conserved protein involved in cell motility, structure, and integrity. Six functional actin isoforms exist and were named based on their electrophoretic mobility and distribution including alpha-cardiac muscle actin (aCAA), alpha-skeletal muscle actin (aSKA), alpha-smooth muscle actin (aSMA), beta-cytoplasmic actin (bCYA), gamma-cytoplasmic actin (gCYA) and gamma-smooth muscle actin (gSMA) (1). The cytoplasmic isoforms, beta-actin and gamma-actin, are nearly identical, differing by only 4 amino acids at the N-terminus with a theoretical molecular weight of 42 kDa (2). Beta-actin is ubiquitously expressed in eukaryotic cells and considered a housekeeping gene which is frequently used as a loading control for assays involving protein detection, such as Western blotting (3,4).

Western Blot Protocol

1. Perform SDS-PAGE (4-12%) on samples to be analyzed, loading 20 ug of total protein per lane.

2. Transfer proteins to Nitrocellulose according to the instructions provided by the manufacturer of the transfer apparatus.

3. Stain the blot using ponceau S for 1-2 minutes to access the transfer of proteins onto the nitrocellulose membrane. Rinse the blot in water to remove excess stain and mark the lane locations and locations of molecular weight markers using a pencil.

4. Rinse the blot in TBS for approximately 5 minutes.

5. Block the membrane using 5% non-fat dry milk + 1% BSA in TBS for 1 hour.

6. Dilute the rabbit anti-actin primary antibody (NB 600-532) in blocking buffer and incubate 2 hours at room temperature.

7. Wash the membrane in water for 5 minutes and apply the diluted rabbit-IgG HRP-conjugated secondary antibody in blocking buffer (as per manufacturer's instructions) and incubate 1 hour at room temperature.

8. Wash the blot in TBS containing 0.05-0.1% Tween-20 for 10-20 minutes.

9. Wash the blot in type I water for an additional 10-20 minutes (this step can be repeated as required to reduce background).

10. Apply the detection reagent of choice in accordance with the manufacturer's instructions (Amersham's ECL is the standard reagent used at Novus Biologicals).

Note: Tween-20 can be added to the blocking buffer at a final concentration of 0.05-0.2%, provided it does not interfere
with antibody-antigen binding.

FAQs for beta-Actin Antibody

Showing  1 - 2 of 2 FAQs Showing All
  • Q: I would like to know whether the antibody anti-actin (NB600-532) from rabbit can be also used for immunofluorescence and which dilution you recommend?

    A: This antibody is listed as being negative for immunocytochemistry/immunofluorescence, so is not recommended for your assay. As it has been validated in ICC/IF, I would highly recommend NB600-501 instead of NB600-532. Full information about this product and recommended dilutions can be found on the datasheet. For ICC/IF, we recommend a dilution of 1:1000-1:2000.

  • Q: What is the immunogen sequence of this Beta-Actin antibody?

    A: A sequence within the N-terminal region of Human beta Actin. The exact sequence is proprietary.
