Blocking peptides and antibody-matched positive controls

Our biomolecules range is divided into blocking peptides for immunodepletion and immunocompetition, and positive controls for western blot. Positive controls are paired with specific corresponding antibodies.

How it works

Two control formats for antibody-based experiments

Blocking peptides in our range are synthetic target-region peptides recommended for use with named antibodies in immunodepletion or immunocompetition experiments. Product records identify the corresponding antibody and peptide region. Positive control preparations are listed for western blot and paired with specific antibodies to provide an expected positive signal when checking the antibody and detection workflow.

Choose the control that fits your workflow

Our biomolecules are organised into two clear categories, blocking peptides for immunodepletion/competition, and positive controls for western blot. Select the format that matches your experimental need.

Immunodepletion & competition Blocking Peptides Synthetic peptides matched to specific antibodies for use in immunodepletion or immunocompetition experiments.

Why use our biomolecules?

✓ Choose the control that matches the experiment
The range separates blocking peptides for immunodepletion or immunocompetition from positive controls for western blot, making the intended application clear at category and product level.
✓ Match reagents to named antibodies
Individual product records identify the antibody recommended for use with the blocking peptide or positive control, supporting product selection by antibody catalogue number.
✓ Check product-specific technical details
Product pages provide specifications, application information, formulation and storage instructions, together with downloadable datasheets and safety data sheets.
Where they are used

Typical applications

✓ Immunodepletion
Select the blocking peptide listed for the corresponding antibody when planning an immunodepletion control.
✓ Immunocompetition
Use the antibody-matched blocking peptide in immunocompetition experiments designed to assess antigen-dependent antibody binding.
✓ Western blot positive controls
Use a positive control with its specified corresponding antibody to check for the expected positive signal in a western blot workflow.
