Multi-rAb Primary Antibodies

Multiclonal recombinant antibody mixtures

Multi-rAb primary antibodies are multiclonal mixtures of recombinant antibody clones that recognize different epitopes of the same protein. Each recombinant clone in the final Multi-rAb mixture is carefully selected after rigorous characterization and screening to ensure the highest level of performance.​

  • Maximum epitope coverage resulting in increased signal and versatility
  • High lot-to-lot consistency and reproducible results throughout the duration of your project​
  • Combines the high sensitivity of polyclonals with the superior specificity of monoclonals
  • Unlimited supply

Our growing selection of Multi-rAb Primary Antibodies are rigorously tested for performance in:

  • Western Blot (WB)
  • Immunoprecipitation (IP)​
  • Immunohistochemistry (IHC)
  • Immunofluorescent staining of tissues and cells (IF/ICC)
3 western blot results side-by-side comparison

3 antibodies against EIF2S1 were tested side-by-side in Western Blot of various cell lysates at a dilution of 1:15,000. On the left is a traditional polyclonal antibody, in the middle is a recombinant antibody clone, and on the right is the Multi-rAb Recombinant antibody mix.

Comparison of AOX peroxisome antibodies

On the left, A549 cells were stained using 10957-1-AP polyclonal AOX antibody at a dilution of 1:200. On the right, HepG2 cells were stained using RMX00007 Multi-rAb Recombinant AOX antibody mixture at the same dilution.
