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.
