ACI-19278
Based on 1 Customer Validation
ACI-19278 is a TDP-43 PET tracer with an average Kd of 25 nM. ACI-19278 only binds to pathological TDP-43 aggregates and does not cross-react with Aβ, Tau, etc. [18F]ACI-19278 successfully visualized the TDP-43 pathology in the human brain through positron emission computed tomography. ACI-19278 can be used for in vivo diagnosis of TDP-43 protein lesions.

Protocol for Hematoxylin-Eosin (H&E) Staining
Hematoxylin-eosin staining is a routine histological method that stains nuclei mainly blue-purple with hemalum and stains cytoplasm, extracellular matrix, and many stromal components pink with eosin, allowing tissue architecture, cell morphology, necrosis, inflammation, fibrosis, tumor growth pattern, and treatment-associated injury to be evaluated by light microscopy. In cancer cells, primary neurons, mouse tumor models, intestinal organoids, inflammatory macrophage preparations, and drug-screening tissues, H&E is a morphology assay rather than a molecular assay; it should be interpreted with complementary molecular or immunostaining assays when the biological question concerns specific proteins, RNA levels, ferroptosis, mitophagy, or immune phenotypes.

Alzheimer’s Disease Modeling
Alzheimer’s Disease (AD) is a neurodegenerative disorder characterized by a progressive decline in cognitive functions and loss of specific types of neurons and synapses. Alzheimer's symptoms can be simulated in mice by injecting drugs (such as Aβ) or genetically modified.
