Loading Control Antibodies
What are Loading Control Antibodies?
Loading controls act as positive controls (internal controls) in applications such as Western blotting. We offer antibodies against housekeeping proteins, including GAPDH, β‑Actin, α‑Tubulin, and Vinculin. Using these antibodies helps verify assay accuracy and normalize or compare the amount of target protein across different samples.
