Secondary Antibodies
Proteintech offers a comprehensive portfolio of secondary antibodies for detecting unconjugated primary antibodies in a wide range of applications including western blot, ELISA, immunofluorescence, immunohistochemistry, and flow cytometry.
Secondary Antibody Range
NEW
Multi-rAb Recombinant Secondary Antibodies are mixtures of precisely engineered recombinant monoclonal antibodies that recognize multiple complementary epitopes on the same IgG. Each recombinant clone in the final multiclonal secondary antibody mixture is carefully selected after rigorous characterization and screening to ensure the highest level of performance.
-
Combines the high sensitivity of polyclonals with the superior specificity of monoclonals
-
Minimal cross-reactivity with off-target species
-
Unlimited supply, high lot-to-lot consistency, and reproducibility of results throughout your project
-
Validated in WB, ELISA, IHC, ICC and Flow Cytometry
Nano-Secondary Reagents
Recombinantly generated alpaca VHHs against human, rabbit, and mouse IgGs suitable for achieving higher image resolution and better tissue penetration due to their smaller size.
Traditional Secondary Antibodies
Traditionally produced polyclonal secondaries offering high sensitivity and available in a wide selection of conjugates and species specificities.
