QVQ is platinum sponsor of the sdAb conference

25 March 2025 QVQ is proud to be the platinum sponsor of THE conference dedicated to the smallest antibody fragment class. We would like to welcome you to mingle with sdAb experts from industry and academia in the fantastic city of Utrecht in September to brainstorm on how single-domain antibodies can further increase their impact on society.

CXCR4-targeting single-domain antibody Q84c as tumor tracer

12 March 2025 This paper, published this week in Bioconjugate Chemistry, is the result of a fruitful collaboration of Stephanie Mareike Anbuhl, Matti Pronker, and Raimond Heukers from QVQ Holding BV and from the group of Prof. Frederik Cleeren at KU Leuven. The sdAb VUN400c proves to be a valuable tool for imaging CXCR4-expressing tumors in vivo. Indium-labeled VUN400c demonstrates tumor-specific uptake and shows promising results in SPECT imaging.Congratulations to all co-authors! QVQ offers this sdAb (Q84) with or without cysteines for conjugations to chelators and many other labels.

Join QVQ at the European Molecular Imaging Meeting

05 March 2025 Next week, Stephanie Mareike Anbuhl will be in Bilbao to join scientists from around the world to discuss the latest developments in molecular imaging. Stephanie will present her poster “Functionalized single-domain antibodies for detecting and imaging GPCR complexes on cancer cells” (Poster# ONCO-006, first session). She will be available for scientific discussions on conjugation of VHHs and the value of these molecules in imaging applications. Will we see you there?

International Day of Women and Girls in Science

11 February 2025 Today we celebrate the International Day of Women and Girls in Science! This day is a reminder to acknowledge and honour the incredible contributions of women and girls in science, technology, engineering, and mathematics (STEM). While significant progress has been made towards gender equality in these fields, a report of the United Nations shows that there is still work to be done. At QVQ, we are proud to have a diverse team. We believe that diversity strengthens our team and supports innovation and excellence in everything we do. QVQ’s growing success is a testament to the power of an inclusive environment where everyone has the opportunity to thrive. We will continue to support and encourage women and … Read more

Contributing to make a difference

04 February 2025 Today is World Cancer Day — a day where millions of people worldwide come together to raise awareness about the importance of education, care, and research in the fight against cancer. Cancer is not just one disease, but a complex group of many, making each case unique and the journey of diagnosis and therapy as well as cancer research highly challenging. Thanks to the ongoing efforts of academia and industry, there is continuous progress with constantly improving treatment options. Yet, the fight against cancer is far from over. While QVQ has no drug pipeline of its own, we do take pride in making a meaningful impact by offering services and products that empower our collaborators and customers … Read more

Single-domain antibody monomerizes CXCR4 and inhibits cancer cell growth and migration

14 January 2025 In this recent preprint, researchers from the VU, AUMC, and QVQ, use single-domain antibodies (sdAbs) to modulate the chemokine receptor CXCR4. Mobach and Bergkamp et al utilize the sdAb VUN401, which disrupts clusters of CXCR4 on lymphoma cells. This monomerization of CXCR4 impairs cancer cell growth and migration and sensitizes cancer cells for apoptosis. CXCR4-targeting sdAbs are available at QVQ as labeled and unlabeled proteins.

Affinity of sdAbs enhanced by various multivalent formats

08 January 2025 QVQ offers unique single-domain antibodies against the class A G protein-coupled receptor CXCR4 (e.g. Q84 and Q85).In this study, QVQ, together with the group of Professor Martine Smit, further improved the already high affinity and antagonistic potency of one of these sdAbs by constructing various multivalent formats. Among all generated formats with up to ten VHH domains in one construct, VHH-Fc stood out as particularly effective for improving affinity and potency. The CXCR4-targeting sdAbs Q84 and Q85 are available as non-modified, cysteine-tagged, and conjugated or genetically fused protein.
