Search our catalog of Primary Antibodies, Nano-Traps & RUO Recombinant Proteins
Proteintech is a leading provider of primary antibodies with an extensive portfolio of polyclonal, monoclonal, and recombinant antibodies. All our primary antibodies are developed and validated in-house by Proteintech scientists to ensure high specificity and lot-to-lot consistency.
Polyclonal Antibodies
Recognize multiple epitopes on the protein of interest. Binds with very high affinity. Good for low abundant targets, rare species and mutated proteins.
Proteintech polyclonals are raised in rabbit.
Monoclonal Antibodies
Recognize a single epitope on the protein of interest. Low background, highly specific. Good for mid-high abundant targets.
Proteintech monoclonal antibodies are raised in mouse.
Recombinant Antibodies
Genetically defined monoclonals, recombinantly produced. Unrivalled reproducibility. Good for long-term, high-level projects.
Proteintech recombinant antibodies are raised in rabbit. Learn more about our recombinant antibody production process.
Nano-Traps
Nano-Traps are ideal for fast, reliable and efficient one-step immunoprecipitation and co-immunoprecipitation. Nano-Traps comprise of Nanobodies conjugated to beads.
RUO Cytokines & Growth Factors
Human Cell (HEK293) expresssed cytokines and growth factors with high bioactivity, stability, lot-to-lot consistency, and native human conformation & post-translational modifications.
