Background

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 (NBP1-47423AF488). (Showing 1 - 5 of 5 FAQ).

1. Why is beta actin used as a loading control in blotting ?
   • 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.
2. Are the beta-Actin antibodies validated in Simple Western?
   • 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.
3. Do Beta-Actin antibodies come in lyophilized format?
   • ACTB antibodies like MAB8969 AND MAB8929 come in lyophilized form.
4. What is the theoretical molecular weight for Beta-Actin antibodies?
   • The TMW for beta Actin antibodies is approximately 42 kDa.
5. I wanted to know which of the two housekeeping genes B-actin or GAPDH can be used for best results. I intend to do an experiment to determine expression of IL-6 and TNF-alpha in liver and kidney tissues.
   • For homogenized tissue, beta-actin and GAPDH are both fine.
