Immunoprecipitation workshop

Introduction to Proteintech

Proteintech has been the original manufacturer of antibodies, ELISA kits, and cytokines and growth factors since 2002. We have antibodies against 13,000 human proteins and we manufacture all our antibodies ourselves and you can only buy our products from us. By cutting out the middleman and not allowing anyone else to sell our products under their label, we offer you full transparency with original validation data and lot-to-lot consistency.

Under our HumanKine label, we manufacture recombinant bioactive proteins expressed in HEK293 cells for native folding, maturation and human glycosylation. Recently became ISO accredited, which means that we can manufacture GMP-grade recombinant proteins for use in cell and gene therapies.

We acquired ChromoTek in 2020 who makes high-quality nanobody reagents including the market leader, GFP-Trap. Most of our Chromotek labeled products are used primarily for Immunoprecipitation.
