Directly conjugated antibodies for immunofluorescence and flow cytometry

Offering reliable and specific research tools for multicolor immunofluorescence and flow cytometry.

Proteins rarely operate in isolation but rather function within multi-subunit complexes. It has therefore become essential to study proteins in their multi-component state rather than individually.

Without the right set of tools, protein analysis can be extremely difficult; cross-species reactivity can arise when using both primary and secondary antibodies (indirect detection), and/or there may be challenges in sourcing appropriately labeled conjugated primary antibodies.

To overcome these issues, we have launched an exclusive range of directly conjugated antibodies with multiple labels. Benefits include

  • Use of RabMAb® technologyrecombinant antibody generation, which provides high antibody affinity and specificity
  • A separation step to remove free dye, thus ensuring a high signal to noise ratio
  • An expanding portfolio overcomes the issue of sourcing conjugates
  • Manufactured in our laboratories to ensure high quality
  • A large selection of pre-adsorbed secondary conjugates to minimize cross-reactivity
  • Supporting data including images, references, and customer reviews is published on each product datasheet
  • Validation in different scientific applications (highlighted in table below), guaranteeing performance
