IHC Guaranteed Antibodies

IHC guaranteed antibodies

We have selected a wide range of IHC validated primary antibodies 
suitable for immunohistochemistry
application, from pathology and cancer research to immunology and
usual biomarkers.

 Loading control antibodies

Loading control antibodies

Loading controls are usually proteins that exhibit high-level,
constitutive expression in the cell type or sample you are studying.
Housekeeping genes are often chosen for use this purpose.

Rabbit Monoclonals 

Rabbit monoclonal antibodies

Rabbit monoclonal antibodies give a better reaction to
antigens than those from rodents such as mice. Using rabbit monoclonal
antibodies is particularly advantageous for more
accurate immunohistochemistry results.

Phospho Antibodies

Phospho antibodies

Protein phosphorylation plays a significant role in a wide
range of cellular processes including cell growth and
proliferation, metabolism, physiological regulation and cell signalling.

Knockout 

KO validated antibodies

In a knockout validation, antibody specificity is confirmed by
testing the antibody of interest on a knockout sample or cell line which
doesn't express the target protein.
