How to choose a secondary antibody
Selecting a secondary antibody that will deliver good performance requires consideration of a number of factors, including features of your primary antibody, the sample, the application, and the detection technology.
Why selecting a secondary antibody should be a primary consideration
A well-chosen, well-made secondary antibody can make a big difference in the quality of your data, supporting the performance of your primary antibody by binding to the primary with high sensitivity and specificity. While your secondary antibody will not compensate for a poorly performing primary, a good primary-secondary antibody pairing should deliver high signal, low background, and clear insight into your scientific question. In this article we discuss how to choose a secondary antibody, covering the different factors you should consider during the selection process.

How to select an isotype control
Produced from normal serum, myeloma serum, and monoclonal cell lines, SouthernBiotech’s purified immunoglobulins make excellent isotype controls and blocking reagents for any application, including flow cytometry and IHC.
When selecting an immunoglobulin as an isotype control antibody, be sure to choose one that is the same as your primary antibody in:
- Host species
- Isotype (i.e., IgG, IgM, etc.)
- Conjugation (if any)
For example, if your primary antibody is a Mouse (IgG2a) Anti-Human CD11a-FITC, you will need a Mouse IgG2a-FITC isotype control.
For the most informative results, we recommend that you use the isotype control antibody at the same concentration as the primary antibody.
