β-Actin Mouse Monoclonal Antibody for Normalization

beta-Actin Mouse Monoclonal Antibody

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 Mouse Primary Antibody with IRDye® Goat anti-Mouse or IRDye Donkey anti-Mouse secondary antibodies.

Other options for housekeeping protein normalization

Reactivity and Specificity

β-Actin antibody is supplied in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and <0.02% sodium azide.

Actin Used for Normalization

Actin used for normalization in
Presence of Smad2/3 in Xenopus embryo lysates. Xenopus embryos were injected with Smad2 RNA and treated with noggin, truncated BMP receptor (tBR), truncated activin receptor (XAR) or BMP4. Lysates were electrophoresed on 12.5% SDS-PAGE gel and proteins were transferred onto PVDF membrane. Membrane was probed for Smad2/3 and β-actin expression using rabbit anti-smad2/3 and mouse anti-actin monoclonal antibody (P/N 926-42212) followed by detection with IRDye 800CW Goat anti-Rabbit IgG (P/N 926-32211) and IRDye 680RD Goat anti-Mouse IgG (P/N 926-68070).

When using an HKP as an ILC for normalization, it’s important to validate the HKP for each experiment to ensure its expression is stable.

Many factors can influence expression including tissue, treatment, and cell density.
