We are thrilled to announce that Infinity Bio has closed our Series A investment, led by the amazing team at Illumina Ventures. As part of the deal, Infinity Bio has acquired Serimmune Inc, a complementary antibody reactome service provider. This event marks a major milestone towards better understanding human immune responses and their role in health and disease. Please contact @InfinityBioInc to learn more about how the antibody reactome can advance your research! businesswire.com/news/home/2025…

Mal-ID integrates three models: analysis of overall repertoire composition, convergent clustering of antigen-specific sequences by edit distance and immune receptor sequence features extracted from a large protein language model. Mal-ID outperformed similar classification approaches with AUROCs up to 0.98, representing a major advancement in diagnostic accuracy when applied to a study cohort of 542 samples. This high level of performance was supportive of the model’s analysis of both BCR and TCR repertoire data, which provided more accurate classification than either receptor type alone, potentially reflecting variation in the roles of B cell and T cell responses in different diseases.

There is an incredible amount “under the hood” here, which we hope will accelerate discovery of novel venom-derived lead compounds. Congrats to all involved for bringing this important project to fruition!

This paper is the culmination of a herculean effort to enable peptide therapeutic discovery using M13 hyperphage, which involved the development of new library design principles, and new cell-based panning and NGS analysis workflows.

Thank you for highlighting our work @us_hupo ! We’re very grateful for this recognition, especially since the project was such a labor of love that spanned many years and collaborations – most notably with the amazing Martin Steinegger @thesteinegger .

Portal and Veranome are currently considering strategic opportunities to advance the LISH-LnR technology and the adjacent supporting assays. If interested in learning more, please reach out!

We also report a system of “molecular rheostats” for tuning LISH-LnR assay performance, a complementary LISH-seq assay for probe panel qualification, and a QC method to determine the quality and availability of fixed tissue RNA.

We’re so excited to present LISH-LnR, a powerful spatial transcriptomic platform spawned in my lab at Johns Hopkins and then spun into a startup company called Portal Bioscience. biorxiv.org/content/10.110…

🎉 Congratulations to @KateGrabowski , PhD (Associate Professor of Pathology, Johns Hopkins School of Medicine Faculty) for winning the Apple Vision Pro raffle at our Open House! 🥳 Thank you to everyone who joined us to explore our innovative MIPSA technology and antibody reactome profiling. Follow us and stay tuned for more exciting updates from Infinity Bio! ♾️ #RaffleWinner #Innovation #Biotech #AntibodyProfiling #Antibody #BaltimoreEvents #Baltimore #BiotechStartups

Last week, we hosted students and faculty from Coppin Academy High School. It was inspiring to see Baltimore's best and brightest experience hands-on STEM experiments and immunology learnings- the future looks bright! 💫 #STEM #Baltimore #Immunology #Reactome

Absolutely agree with @EricTopol ! 🙌 Characterizing the "immunome"—from lifetime viral exposures to autoantibody reactivities—provides critical insights into disease mechanisms and biomarker development. We are the leader in comprehensive antibody reactome profiling, and are actively supporting academic and industry translational discovery research 🤝 with our RUO assays: VirSIGHT (all human viruses) and HuSIGHT (all human protein isoforms). While direct-to-consumer applications are certainly on the horizon, today we are helping researchers lay the groundwork for better understanding of antibody reactomes. Check out our RUO libraries here: infinitybio.com/infinity-profi…. 👏♾️ #academia #Antibody #AntibodyReactomeProfiling #AntibodyResearch #BiotechInnovations #HumanStudies #Immunotherapy #BiotechStartups #Biotech

Calling local biomedical professionals! Please attend our open house to learn how your cohort study can benefit from antibody reactome profiling. You'll get to see our beautiful Baltimore lab and can enter to win a new Apple Vision Pro 🤯 Please RT to help spread the word!

Taking Pharokka output as input, Phold uses the ProstT5 protein language model to rapidly convert amino acid sequences to Foldseek 3Di structural tokens, & then searches these with Foldseek against a database of 1M+ phage protein structures folded with Colabfold (2/n)

A fantastic collaboration with @thesteinegger and very excited about future projects using this type of approach to discover novel peptide therapeutics. If you have ideas for applications or indications, please reach out to us!

New paper (bit.ly/3TdtbS5) in @AdvSciNews (Advanced Materials) describes novel biomaterial scaffold, the “artificial lymph node matrix,” to stimulate production of antigen-specific T immune cells. @Natalie_K_L @HopkinsMedicine @JHUPath @JHUBME @JHUMaterials @TTECJHU

If you do epi or work on a cohort study, you’ve probably captured nature (genetics 🧬) --- now it’s time to capture nurture (exposures and infections 🦠), through the lens of the immune system! Please reach out to jp.laine@infinitybio.com for more info!

Check us out at infinitybio.com. We have a state-of-the art purpose-built lab in Baltimore, MD, USA. Our quality assurance system and management team ensure that your samples and data are tracked safely and securely throughout the entire process.

Our novel MIPSA technique is used to create large libraries of DNA-barcoded peptides or full-length proteins. Both catalog libraries (currently virome, human proteome, allergome) and customer designed libraries can be mixed and matched for small to large scale studies.
