Neurodegenerative Diseases

Neurodegenerative diseases in 3D

Depositions of aberrant protein aggregates in the brain are recognized hallmarks of major neurodegenerative disorders like Alzheimer’s, Parkinson’s, and Huntington’s diseases. LifeCanvas offers researchers the opportunity to process and analyze samples for β-amyloid deposition (e.g. in Alzheimer’s) and for the accumulation of α-synuclein in Lewy Bodies (e.g. in Parkinson’s).

Localized damage to diseased brain parenchyma is often accompanied by a neuroinflammatory response, such as activation and recruitment of reactive glia (e.g. astrocytes, microglia). Our technologies can be used to assess these responses through mapping of astrocytes (GFAP+) and microglia (IBA1+) in animal disease models.

Full service tissue processing

Upon receiving your samples, LifeCanvas technicians:

  • Use SHIELD to preserve sample integrity and antigenicity
  • Actively clear and immunolabel tissue with specific antibodies (e.g. β-amyloid, α-synuclein, Phospho-tau, GFAP, IBA1, etc) using SmartBatch+
  • Index-match samples with EasyIndex
  • Acquire volumetric light sheet images with SmartSPIM
  • Analyze post-processed images with SmartAnalytics to determine levels of protein aggregation for regionally specific brain areas

From brain samples to publishable data

You send us: PFA-fixed brain samples from your disease model animals

We deliver:

  • Regional cell counts and quantification of protein aggregates registered to the Allen Brain Atlas
  • Heat maps showing localized levels of neuroinflammation and protein deposition
  • Coronal views with Atlas overlays depicting detected cells and aggregates throughout the whole brain volume
