α-Synuclein (61-75) is the 61-75 fragment of α-Synuclein. α-Synuclein is an abundant neuronal protein that is highly enriched in presynaptic nerve terminals. α-Synuclein is a potential biomarker for Parkinson's disease (PD).

Description

In Vitro

Lewy bodies containing α-Synuclein are a neuropathological hallmark of PD, and missense mutations in α-Synuclein (A30P, E46K, H50Q, G51D, A53E, A53T), as well as α-Synuclein gene duplications and triplications, appear to cause PD. Moreover, polymorphisms in regulatory elements of the α-Synuclein gene predispose individuals to PD and are linked to an early onset of the disease. The non-Aβ-amyloid component (NAC) region of α-synuclein is relatively hydrophobic and aggregation-prone in human α-Synuclein but not in mouse α-Synuclein nor in the corresponding homologous region of human β-synuclein. Yet, β-synuclein is more homologous to α-synuclein in the N-terminal sequences (74%) than γ-synuclein (67%)^[1].

Peptide Solubility and Storage Guidelines:

1. Calculate the length of the peptide.

2. Calculate the overall charge of the entire peptide according to the following table:

	Contents	Assign value
Acidic amino acid	Asp (D), Glu (E), and the C-terminal -COOH.	-1
Basic amino acid	Arg (R), Lys (K), His (H), and the N-terminal -NH₂	+1
Neutral amino acid	Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q)	0

3. Recommended solution:

Overall charge of peptide	Details
Negative (<0)	1. Try to dissolve the peptide in water first. 2. If water fails, add NH₄OH (<50 μL). 3. If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (>0)	1. Try to dissolve the peptide in water first. 2. If water fails, try dissolving the peptide in a 10%-30% acetic acid solution. 3. If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0)	1. Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first. 2. For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.
