Buy Your Antibodies Straight from the Source!

Since we are an original manufacturer, we have our antibody products on hand in our lab freezers and can ship orders the same day we receive them*. We don’t have to wait on suppliers to ship us antibodies to then ship to you. You know where your antibody came from, and won't waste time waiting for reagents.

We ship our orders via FedEx Standard Overnight or Express International service to ensure your order is delivered as quickly as possible.

What makes us different?

  1. If we attempt to make an antibody and it doesn’t work, we throw it away. We never sell an antibody that we can’t get to work in our hands.
  2. Our commitment to strict validation standards ensures a clean signal in endogenous protein and verifies phosphospecificity for relevant products.
  3. We are dedicated to reproducibility. Look for our “Pooled Serum” icon. Each antibody with this icon is purified from its own pool of serum to ensure lot-to-lot consistency.
  4. We guarantee our antibodies. If you can’t get the antibody to work in your application, we will provide a 100% refund.
  5. When making a custom antibody, we provide personalized customer support from start to finish, from peptide design, to purification, to characterization.
