About Us

A mission to create smarter scientific tools

It Started with Effortless Immunohistochemistry

Work smarter not harder

Kromnigon is a biotech company that originated from new technologies for multicolor microscopy and multiplex IHC. The company was founded in 2015 by Per Fogelstrand and Ulf Yrlid. It started as a joint research project at Gothenburg University, Sweden, which focused on the involvement of leukocytes in endothelial repair. The task posed significant histological challenges, and from these frustrations, new ideas emerged on how to convert multiplex IHC from craftsmanship into reliable methods that anyone in the lab can perform. Today, we have several IHC kits available on the market for multiplex immunostaining, along with exclusive bandpass filter sets that equip fluorescence microscopes with 7 color channels.

Our IHC kits are based on StreptaClick®, a streptavidin molecule optimized for pre-mixing with biotinylated antibodies before use in experiments. We are continuing developing StreptaClick®-products for instant antibody labeling with a wide range of signalling molecules and for custom click applications, where StreptaClick® carries a pre-determined number of alkynes or azides.

In 2021, Kromnigon secured funding for expansion and is now operating from premises located at AstraZeneca BioVentureHub in Gothenburg.

Our team

Per Fogelstrand, PhD

CEO & Founder

Per co-founded Kromnigon in 2015 and as CEO, he has been directing the company towards expansion. His emphasis is on product development, strategic planning, raising capital, and establishing a high-performing team. Per has a background in chemistry and biology, and a PhD in Vascular Surgery. Per has extensive experience of histological techniques and was the PI of a cardiovascular research group for many years at the University of Gothenburg. The core technologies in Kromnigon were initially developed in parallel with a cardiovascular project looking at endothelial repair in mouse arteries (PLoS One. 2015 Mar 4;10(3), J Leukoc Biol, 2019, 105(1)).

Ulf Yrlid, Professor

Scientific Advisor & Founder

Ulf co-founded Kromnigon in 2015 and as Scientific advisor provides expert consultation on scientific and technological matters. He contributes to the strategic plans and with his deep knowledge in immune cell infiltrates in tissues and cell surface receptor-ligand interactions he guides the product development. Ulf is a Professor in Mucosal Immunology and Microbiology at the University of Gothenburg where his research group focuses on ways to improve immune responses against colorectal cancers and enterotoxins. He has more than sixty scientific publications.

Panagiota Georgoulia, PhD

Senior R&D Scientist, Laboratory and Production Manager

Panagiota brings over 15 years of experience in interdisciplinary projects across computational and structural biology, biochemistry, and protein engineering, with specialization in molecular modeling and wet lab techniques. Her background is in Molecular Biology & Genetics, as well as a PhD in Computational Biology. Her most significant achievement was the development of FOSY NMR for fast detection and identification of hotspots in proteins of biopharmaceutical interest (Angew. Chem, 2021, 60, 1-6, Cover). At Kromnigon, she is combining protein engineering, bioconjugations and advanced chromatography to successfully develop next generation StreptaClick® products from idea into market-ready products.

Despoina Chatzikosmidou, M.Sc.

Sales Representative

Despoina holds a master’s degree with an interdisciplinary focus on biomedicine and biomaterials engineering from Karolinska Institutet and Aalto University. She has experience working in diverse research groups, where she has utilized a wide range of technical applications including SEM, TEM, Fluorescent Microscopy, Confocal Microscopy, DSC, TGA, FTIR, UV/Vis Spectroscopy, Rheometry, NMR, HPLC, FPLC, Tensile Tests, DLS, 3D printing, chemical synthesis, and cell culture. In addition to her research experience, Despoina has managed commercial projects in the B2B sectors of biotechnology and pharmaceuticals. These projects involved market potential analysis, opportunity identification, market and trend analysis, competitive and benchmarking analysis, as well as the identification of industry needs and pain points.


Kromnigon is located within the premises of AstraZeneca R&D (Gothenburg, Sweden)
