Secondary Antibody SKU Replacement Guide

We have combined the best of the BioSource™, Caltag™, Molecular Probes® and Zymed® secondary antibodies to help you get the most out of your experiments.   It is easy to use this guide to find the best conjugate to replace your current secondary antibody conjugate. 

  • Look for your old SKU number in the first column.
  • Find the new SKU number in the third column.
  • Look in the fifth column to see if we have a comparable Alexa Fluor® dye conjugate for brighter, more photostable fluorescence signal.
