DAT PET Tracks Dopamine Graft Maturation in Parkinson’s
2026-09-23
Goggi et al. evaluated whether longitudinal PET imaging can track the maturation and function of transplanted human stem cell-derived dopaminergic neurons in a rat model of Parkinson’s disease. Their findings support dopamine transporter imaging as an in vivo indicator of graft differentiation, while showing that imaging readouts reflect distinct aspects of presynaptic integrity and dopamine function.

Patient-Derived Gastric Cancer Assembloids
2026-09-23
Shapira-Netanelov and colleagues developed a patient-derived gastric cancer assembloid that combines tumor organoids with matched stromal cell subpopulations. The model captures tumor–stroma effects on gene expression and drug sensitivity, providing a more physiologically relevant platform for resistance studies and personalized treatment testing.

AO/PI Double Staining Kit: Practical Guide
2026-09-22
The AO/PI Double Staining Kit provides a rapid fluorescent cell staining workflow for separating viable, apoptotic, and necrotic cell populations in one assay. It is useful for comparative cell viability and cell-death assessments, but it should not be used as a standalone confirmation of apoptosis mechanism or as a substitute for orthogonal validation.

GPR107 Deficiency in Diabetic Nephropathy
2026-09-21
Xu et al. identify GPR107 as a regulator of podocyte collagen IV homeostasis and show that its deficiency aggravates diabetic nephropathy through defective AT1R endocytosis and pathological Ca2+/CREB signaling. The study connects membrane-receptor trafficking with extracellular-matrix turnover, providing a mechanistic framework for interpreting glomerular basement membrane thickening in diabetic kidney disease.

Cy7 NHS Ester: Practical Labeling Guide
2026-09-20
Cy7 NHS ester (SKU A8109) is a water-soluble near-infrared dye for bioimaging that enables amino-group labeling of proteins and peptides without requiring an organic co-solvent. It is suited to carefully controlled in vitro and exploratory in vivo workflows, but not to targets lacking accessible amino groups or long-term storage of prepared dye solutions.

PreScission Protease (PSP): Practical Tag Cleavage
2026-09-19
PreScission Protease (PSP) is an HRV 3C protease fusion enzyme for sequence-directed removal of affinity tags from recombinant proteins. It is appropriate when the defined LEVLFQGP cleavage sequence is present and cold processing is acceptable, but it should not be treated as a general-purpose protease or applied without construct-specific validation.
