The Best 3 IHC Troubleshooting Tips

Being interested in completing your IHC process is streamlined and flawless; you need to consider the following tips:

Tip #1

Make sure to use positive and negative controls to verify the primary antibody specificity

Primary antibodies can fail to locate their target antigen for numerous reasons. For instance: Conformation adjustments related to fixation/embedding steps like in FFPE, steric drawback, post-translational modification.

Moreover, antibodies can halt non-specifically to other objectives or tissue components. There are some IHC troubleshooting tips to get the best results. For this, it will be needed to evaluate the specificity of the antibody, other than checking in its datasheet that its use has been confirmed for the precise IHC method for use alongside including the performance of poor controls and determining the highest dilution.

Tip #2

Make sure to use proper tissue preparation

The fact is, the manner to prepare the tissue analyzed also influences experimental effects, even when they use relatively particular and properly-characterized antibodies. These consequences arise mainly from epitope overlaying because of fixation-induced conformational modifications and unsuccessful of the antibody to penetrate the tissue.

In this case, tissue samples may be frozen or fixed:

• Freezing the sections keeps the conformation of the target antigen permitting superior antibody binding. But small crystals of ice render these sections mistaken for long-time period garage.
• Besides, Fixed and embedded tissue are a higher opportunity for long-term storage.

This one of the best IHC Troubleshooting tips.

Tip #3

Make sure to use the top-notch cross-adsorbed secondary antibodies

Secondary antibodies are used in massive concentrations in Immunohistochemistry, with the chance of binding non-specifically to tissue additives resulting in high background. They can cross-react with IgGs from other species as well. To decline cross-reactivity, it's far beautiful to apply tremendously cross-adsorbed secondary antibodies.

To check for specificity, you can take a look at the secondary antibodies within the absence of the primary antibodies. If appearing IF, take note of auto fluorescent molecules that can be available in the tissues, moreover, restrict the usage of directly conjugated antibodies only in favor of those target proteins which can be huge or massive within the cell.
