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).

FAQs for beta-Actin Antibody

Showing  1 - 5 of 6 FAQs Showing All
  • 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.

  • Q: Why is beta actin used as a loading control in blotting ?

    A: Beta actin is a highly-expressed protein found in all cells, and is considered a house keeping protein whose expression is necessary for any cell's proper functioning. For this reason it is used as a loading control to confirm that the same amount of total protein is loaded in each lane of an SDS-PAGE gel so that appropriate comparisons can be made between the actual proteins of interest in different samples.

  • Q: Are the beta-Actin antibodies validated in Simple Western?

    A: Yes, we offer a few beta actin antibodies that have been tested in Simple Western: NBP1-47423, NB600-501, NB600-532, NB600-503, and NB100-56874.

  • Q: Do Beta-Actin antibodies come in lyophilized format?

    A: ACTB antibodies like MAB8969 AND MAB8929 come in lyophilized form.

  • Q: What is the theoretical molecular weight for Beta-Actin antibodies?

    A: The TMW for beta Actin antibodies is approximately 42 kDa.

  • Q: Do Beta-Actin antibodies come in lyophilized form?

    A: ACTB antibodies like MAB8969 AND MAB8929 come in lyophilized form.
