Loading Control Antibodies
Normalise every blot with confidence
Housekeeping antibodies against GAPDH, β-actin and α/β-tubulin — sharp, single-band reagents for accurate protein normalisation in western blotting, in mouse, rabbit and HRP-conjugated formats.
Housekeeping targets for normalisation
Choose by target, host and molecular weight so your loading control sits clear of your protein of interest.
Anti-GAPDH Monoclonal (CABC002)
Anti-β-Actin Monoclonal (CABC004)

HRP GAPDH Monoclonal (CABC035)
β-Actin Rabbit Monoclonal (CABC038)
β-Tubulin Rabbit Polyclonal (CABC008)
GAPDH Rabbit Polyclonal (CABC001)
Reliable normalisation, every time
Accurate normalisation
Stable, ubiquitously expressed housekeeping targets for reliable sample-loading correction.
Single sharp band
High specificity gives one clean band at the expected weight — easy to interpret.
Host & conjugate choice
Mouse and rabbit hosts, unconjugated or HRP-direct, to fit any multiplex blot.
Recombinant & citable
Reproducible, batch-consistent antibodies cited in peer-reviewed studies.
Pick the right loading control in three steps
Mind the molecular weight
Pick a control whose band sits clear of your target — GAPDH ~37 kDa, β-actin ~42 kDa, tubulin ~50 kDa.
Match the host
Choose a host different from your primary (or use HRP-direct) to avoid secondary cross-reactivity on multiplex blots.
Pick the format
Unconjugated for flexibility, or HRP-conjugated for a faster one-step detection workflow.
