Catalog

ASAP is committed to accelerating the pace of discovery and informing a path to a cure for Parkinson’s disease through collaboration, research-enabling resources, and data sharing. We’ve created this catalog to showcase the research outputs and tools developed by ASAP-funded programs.

Protocol

Protocol Collection: Combinatorial selective ER-phagy remodels the ER during neurogenesis

This molecular inventory of ER proteome remodeling and versatile genetic toolkit provides a quantitative framework for understanding contributions of individual ER-phagy receptors for reshaping ER during cell state transitions.

Protocol

Human primary fibroblast culture

This is a protocol for human primary fibroblast culture.

Protocol

Clusterin cellular uptake assay

This protocol details how to efficiently monitor Clusterin and Clusterin/Substrate uptake in different cell types like HEK293T, iNeurons, and iMicroglia.

Protocol

N_terminal protein labeling

This protocol details how to efficiently label a protein at the N-terminus using Clusterin protein as example.

Protocol

Formation and isolation of Clu phospholipid particles

This protocol details how to efficiently make in vitro and isolate Clu-phospholipid particles using purified Clusterin from HEK293E cells (dx.doi.org/10.17504/protocols.io.bvvkn64w) and 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC).

Protocol

Cytokine profiling analysis on conditioned medium of human neurons using Luminex multiplex assay

This protocol is used to identify secreted inflammatory factors by cytokine profiling of the conditioned medium from human transdifferentiated neurons of healthy donors and AD patients.

Protocol

Immunohistochemistry on free-floating and paraffin-embedded tissue sections

This protocol is used for free-floating frozen (30-50 microns) and paraffin-embedded (10 microns) tissue sections.

Protocol

Cloning, protein expression, and purification of 20S CPs and assembly intermediates

This protocol details methods for cloning, expression, and purification of 20S CPs, and assembly intermediates for biochemical and structural analysis.

Protocol

Structural analysis of 20S CPs and assembly intermediates by electron cryo-microscopy

This protocol details methods for structural determination by transmission electron cryo-microscopy of 20S CPs and assembly intermediates.

Protocol

Neural differentiation on EM grids – iNeurons sample preparation for cryo-ET and CLEM

A protocol for differentiating AAVS1-TRE3G-NGN2 hESCs to iNeurons directly on EM grids for cryo-ET and cryo-CLEM. The protocol includes: (1) EM grids coating with Matrigel or Poly-Ornithine and Laminin; (2) differentiation and seeding of iNeurons on EM grids; (3) lentiviral transduction for transient expression of fluorescently-labeled proteins; and (4) plunge freezing.
