IHC Guaranteed Primary Antibodies

IHC-Guarantee primary antibodies

We have selected a wide range of IHC-validated primary antibodies suitable for immunohistochemistry applications, covering pathology, cancer research, immunology and other usual biomarkers.

  Loading control antibodies

Loading control antibodies

Loading control antibodies target proteins which typically exhibit ubiquitous expression. There use is valuable in determining relative protein concentration and in determining the successful transfer of protein in western blots.

Rabbit monoclonal antibodies

Rabbit monoclonal antibodies

Rabbit monoclonal antibodies can exhibit a greater binding affinity 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 post-translational cellular processes including cell growth and proliferation, metabolism, physiological regulation and cell signalling.

Knockout validated primary antibodies

KO-validated primary antibodies

        In a knockout validation, antibody specificity is confirmed by testing the primary antibody of interest against a sample from a tissue or cell line which does not express the protein of interest as well as a positive control which does.

Goat primary antibodies

Goat primary antibodies

Goat primary antibodies are ideal for large scale projects at a low cost. We have over 3000 goat primary antibodies suitable for various applications.

Tag antibodies

Tag antibodies

Tag antibodies are frequently used with recombinant protein cell cultures to allow researchers to selectively extract a target protein from the endogenous samples. One of the most popular is our Anti-mCherry-Tag antibody used widely in gene expression assays.
