New Insect Sf9-ET Cell Line for Determining Baculovirus Titers

The baculovirus-based protein expression system has gained increased prominence as a method for expressing recombinant proteins that are used in a wide range of biomedical applications. An important step in the use of this system is the ability to determine the virus infectious titer, i.e., the number of active baculovirus particles produced during an infection of the insect host cell.

SMAD3 Reporter Mouse for Assessing TGF-ß/Activin Pathway Activation

The Transforming Growth Factor Beta (TGF-ß) ligands (i.e., TGF-ß1, -ß2, -ß3) are key regulatory proteins in animal physiology. Disruption of normal TGF-ß signaling is associated with many diseases from cancer to fibrosis. In mice and humans, TGF-ß activates TGF-ß receptors (e.g., TGFBR1), which activates SMAD proteins that alter gene expression and contribute to tumorigenesis.  Reliable animal models are essential for the study of TGF-ß signaling.

Minibody for Conditioning prior to Hematopoietic Stem Cell and Progenitor Cell Transplantation

Patient conditioning is a critical initial step in hematopoietic stem and progenitor cell (HSPC) transplantation procedures to enable marrow engraftment of infused cells. Conditioning regimens have traditionally been achieved by delivering cytotoxic doses of chemotherapeutic agents and radiation. However, these regimens are associated with significant morbidity and mortality, and cannot be used safely in elderly or subjects with comorbidities.
