Loading Control Antibodies for Western Blotting

Loading control antibodies are used as tools to ensure equal loading of a gel during western blot and are helpful when compare the western blot results qualitatively or quantitatively. Loading control antibodies are against loading controls which are usually encoded by housekeeping genes and express stably at high levels in many cell lines and tissues. Some common loading control antibodies include Actin, Beta Actin, COX IV, GAPDH, Histone H3, Alpha Tubulin and Beta Tubulin, etc.
Sino Biological offers reliable loading control antibodies with molecular weight from 16 kDa ~ 75 kDa, for the detection of whole-cell proteins, cytoplasmic proteins, mitochondrial proteins and nucleoproteins. In addition, we also offer Transferrin antibody which can be used as loading control in serum sample.

Find The Right Loading Control Antibodies

  • • Expression factors - Make sure that the loading control is expressed ubiquitously at high levels in your samples and its level isn't affected by experiment conditions.
  • • Expression location - Check carefully that the loading control and your protein of interest are expressed in same location.
  • • Molecular weight - At least 5 kDa size difference between your protein of interest and the loading control ensures you can distinguish the bands.

Keep the above tips in your mind, and find the right loading control antibody for your experiments using the following table.
