Polyclonal Antibody Production

Price on request

All Proteintech polyclonal antibodies are affinity purified and tested by indirect ELISA and Western Blot on unmodified lysates. 95% of Proteintech polyclonal antibodies are raised against whole proteins. There are several advantages to using a full-length protein immunogen for polyclonal antibodies:

  • Since the immune system can generate antibodies against any region of the whole protein, there is a high chance of reactivity across species due to conservation.
  • Some regions of the protein may be better for one application than another, so the availability of the whole protein yields antibodies that can work for multiple applications.
  • Protein immunogens are best for cases where one needs to follow a protein while it is modified, such as investigating the processing of a protein over time.

Discover Proteintech’s full range of polyclonal antibodies that will advance your research. We have antibodies against 12,000 targets available.

Monoclonal Antibody (mAb) Production

Price on request

Proteintech offers a broad monoclonal antibody product line. Each Proteintech monoclonal antibody has a unique manufactured in-house clone number. The high specificity with one epitope target makes our monoclonal antibodies very efficient, reflecting in less background staining and low cross-reactivity with other proteins. Also, high homogeneity of Proteintech monoclonal antibodies ensures minimal batch-to-batch variations, making the results easy to reproduce.

Recombinant Protein Expression

Price on request

Humankine products are created in HEK293 cells using animal-free components. Our human expression system ensures that proteins have native conformation and post-translational modifications to optimize biological activity. No expression tags, xeno-free…just high quality proteins.

  • Animal-free and tag-free
  • Made from human HEK293 cells.
  • Native post-translational modifications and folding
  • Can be used for culturing human stem cells for regenerative medicine
