Gamma Proteins

The founders of Gamma Proteins passionately believe that the cost of protein reagents should not be prohibitive to scientific research and for this reason have formed a company with the mission to increase the quality and reduce the cost of recombinant proteins. Specifically, we are focussed on the supply of Fc gamma receptors and FcRn in bulk quantities to customers worldwide through a network of trusted distributors.

Gamma Proteins

Product Range

Gamma Proteins supplies a full range of human Fc gamma receptors (FcγR) and FcRn (other species launching soon). All products are available in unconjugated or biotinylated forms, are of extremely high purity and with full biological activity confirmed by surface plasmon resonance (SPR). 

Product Range


Over the last few decades recombinant protein production has undergone a revolution. The costs of DNA sequencing and gene synthesis have fallen sharply and advances in mammalian transient expression have made gram per litre level expression of many proteins routine. Despite these advances the cost of critical research reagents, especially recombinant proteins, has risen with micrograms of protein often costing hundreds of pounds.

The founders of Gamma Proteins are experienced scientists with deep knowledge of recombinant protein expression, purification and quality control as well as the supply of reagents and services to the bio-pharmaceutical industry. We were founded in the United Kingdom in 2023 with a vision to deliver substantially lower cost protein reagents to scientists worldwide without compromising on purity and biological activity.


Why Use Our Products?

Although making our products highly affordable is at the core of what we do, we do not let this compromise quality. All of our proteins meet very strict purity criteria and are SPR validated. Below are 8 reasons why we believe you should trust our proteins:

Gamma Proteins icon 1 Purity – Final product purity is determined by SEC-HPLC with a quality threshold >95% monomer purity.

Gamma Proteins icon 2 Activity – Biological activity of recombinant proteins is confirmed by Surface Plasmon Resonance.

Gamma Proteins icon 3 Mammalian Expression – All recombinant proteins are produced in Human Embryonic Kidney 293 (HEK293) cells, ensuring correct folding and post-translational modification.

Gamma Proteins icon 4 Animal Free – All proteins are manufactured in an animal component free platform with no carrier proteins added to the final products.

Gamma Proteins icon 5 Reproducibility – All proteins are produced recombinantly, and quality & activity is confirmed for every batch.

Gamma Proteins icon 6 Low Endotoxin – All products are prepared in an endotoxin free process to ensure they have < 1 EU/mg.

Gamma Proteins icon 7 Site-specific Biotinylation – All products contain an AVI-tag for site-specific biotinylation ensuring greater reproducibility and preferential orientation for assays.

Gamma Proteins icon 8 Lyophilised – All products come lyophilized for longer stability and reduced environmental impact from transport.
