The β-actin primary antibody can be used as an internal loading control (ILC) for normalization.
The expression of β-actin, or any housekeeping protein (HKP), should be validated to ensure that its expression does not change under experimental conditions.
Once validated, β-actin primary antibodies can be used for the detection of β-actin when performing two-color detection.
Detect β-Actin Rabbit Primary Antibody with IRDye® Goat anti-Rabbit or IRDye Donkey anti-Rabbit secondary antibodies.
Other options for housekeeping protein normalization
