**MilliporeSigma** has entered into an agreement to acquire **Natrix Separations**, an Ontario, Canada-based provider of hydrogel membrane products for single-use chromatography, for an indisclosed amount. The acquisition is intended to complement MilliporeSigma’s efforts to drive next-generation bioprocessing, ultimately enabling faster, more efficient technology for customers.

**CSL Limited** is buying Tucson, AZ-based **Calimmune** for $91 million upfront and up to $325 million in performance-based milestones. As part of the deal, CSL will pick up Calimmune’s preclinical product CAL-H, an hematopoietic stem cell gene therapy to treat sickle cell disease and beta-thalassemia. It will also acquire two proprietary platform technologies, Select+ and Cytegrity. Select+ drives selection of genetically modified stem cells once they are infused back into patients, which decreases toxicity and improves efficacy. Cytegrity is a scalable manufacturing technology for the manufacture of lentiviral vectors, which are used to deliver the engineered genes.  
  
**Sanofi** has completed the acquisition of **Protein Sciences**, a vaccines biotechnology company based in Meriden, CT. Through the acquisition, Sanofi Pasteur adds a promising product to its influenza vaccine portfolio: Flublok (influenza vaccine), the only recombinant protein-based influenza vaccine approved by FDA. The acquisition also fits with Sanofi Pasteur’s strategic initiative to explore non-egg-based influenza vaccine manufacturing technologies. *"*
