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.
mRNA purification by translating ribosome affinity purification (TRAP) of DAT-expressing cells (dopaminergic neurons) in mouse ventral midbrain
This protocol describes the capture of eGFP-L10a-tagged ribosomes and mRNA from DAT-expressing cells (dopaminergic neurons) in mouse ventral midbrain.
Teams
Differentiation of human medium spiny neurons (MSNs) from induced pluripotent stem cells (iPSCs)
This protocol generates human medium spiny neurons (MSNs) from induced human pluripotent stem cells (iPSCs).
Teams
Differentiation of human cortical neurons (CNs) from induced pluripotent stem cells (iPSCs) and their coculture with rat astrocytes
This protocol described the production of human cortical neurons from induced pluripotent stem cells in cocultured with commercially available rat astrocytes.
Teams
Quantification of extracellular 𝜶-synuclein assay
This protocol uses a classical ELISA experimental design with sensitive electrochemical detection to provide a measure of 𝜶-synuclein concentration in the conditioned media of cultured iPSC-derived human cells.
Teams
Membrane and cytosol fractionation
This protocol describes membrane and cytosol fractionation of cells expressing different DNAJC5 isoforms.
Teams
In vitro depalmitoylation assay
This protocol describes the in vitro depalmitoylation assay of DNAJC5.
Teams
CRISPR/Cas9 genome editing
This protocol describes the generation of DNAJC5 KO using CRISPR/Cas9 edition.
Teams
Medium fractionation and EV preparation
This protocol describes the characterization of the extracellular alpha-synuclein and DNAJC5.
Teams
Co-immunoprecipitation
This protocol describes a common procedure to perform co-immunoprecipitation.
Teams
Mitochondria purification
This protocol describes how to purify mitochondria from cell culture.
Teams
Differentiation of SH-SY5Y cells
This protocol describes a standard procedure to differentiate SH-SY5Y cells into dopaminergic neurons using retinoic acid.
Teams
shRNA knockdown
This protocol describes a standard procedure to generate a stable cell line for a DNAJC5 knockdown using shRNA.
Teams
Immunoblots
The steps of this protocol are similar for different sources of protein such as cell lysate, cytosol, or membrane samples, and EV samples. However, some specific changes depend on the protein of interest, endogenous alpha-synuclein, or type of cells, hiPSC dopamine neurons.
Teams
Fura-2 imaging of ionomycin response, with and without R568; a CaSR positive modulator
Fura-2 imaging protocol to accompany Kilfeather, Khoo et al., 2023: Single cell spatial transcriptomic and translatomic profiling of dopaminergic neurons in health, aging, and disease.
