Today I am going to share with you our data for the top 100 catalogue proteins used in research in 2019 around the world – this is the first time we’ve shared this ranking and we’ll continue to revisit this data in coming years to see how the market changes. 

I last blogged about the protein data I’ve been working with in May, when I highlighted that we had 238,000 products from 51 suppliers, with MilliporeSigma, R&D Systems and Peprotech held the majority of the market.

Since May I have added even more data to this set, taking us up to 98 suppliers and more than 338,000 products. Our protein dataset includes a range of protein types such as streptavidins, enzymes and growth factors.

For today’s analysis I have focused on the citation data for protein use from publications in 2019. 

Despite MilliporeSigma holding just under 60 per cent of the total protein market, we do see a good mix of companies featured in the top 100 products. MilliporeSigma, as expected, claims the lion’s share with 53 products, followed by Peprotech with 30 and R&D Systems with 13. We also see Jackson ImmunoResearch, Biolegend and SolarBio in the top 100. 

The top six products are all from MilliporeSigma – with two of these being different versions of their Bovine Serum Albumin. This is used extensively throughout laboratory research as a protein concentration standard, so it isn’t surprising to see them claim a large percentage of citations. 

Peprotech enter the chart in seventh place, with Recombinant Human FGF-basic with 357 citations in total, 65 of which were in 2019. 

Some of the outlying companies are also worth a mention – Thermo Fisher Scientific fall just outside the top 100, with their first product – EGF Recombinant Human Protein – being placed at 126th place, and Abcam’s Streptavidin (HRP) places at 161st. Otherwise, there are no additional companies featured in the top 200 than we see in the top 100 proteins. 

I’m excited to continue to see this dataset grow over the next year. One of my next steps with this data is to include more molecular biology proteins to increase the scope . If your company supplies these then I would love to hear from you – please could you contact me on  

Today I am making the data for the top 100 proteins available for you to download and analyse. Sign up below and we’ll send it to your inbox, and if you’ve any questions about our protein dataset then do get in touch and I’ll be happy to have a chat with you about it.
