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 Controls

Loading Controls

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 Monoclonals

Rabbit monoclonal immunoglobulins 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 signaling

Knockout 

KO Validated Antibodies

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

Goat Primary Antibodies

Goat Primary Antibodies

Goat primary antibodies are ideal for large scale projects at a low cost.
We have +3000 goat primary antibodies suitable for any experiment. 

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 the Anti-mCherry-Tag antibody used widely in gene expression assays.
