Welcome to Entry Card of Peptide

Details of SAPdb ID 1014

Primary information
SAPdb_ID	1014
PMID	12714741
Year	2003
Name	NH2-D-Phe-D-Phe-COOH
Sequence	ff
N-Terminal Modification	Free
C-Terminal Modification	Free
Non-terminal Modication	None
Length	2
Peptide/Conjugate/Mixture	Peptide
Conjugate Partner	None
Technique	TEM (Transmission Electron Microscopy)
Solvent	Aqueous dispersion
Method	NH2-D-Phe-D-Phe-COOH dipeptide solublized at very high concentrations ( >=100 mg/ml) by dissolving the lyophilized peptide in 1,1,1,3,3,3 hexafluoro-2-propanol. The peptide appeared to be highly soluble in the organic solvent, a rapid assembly into ordered semicrystalline structures was observed visually within seconds after dilution into the aqueous solution at a final µM concentration range.
Concentration	>=100 mg/ml stock soln
pH	NA
Temperature	80°C
Incubation Period	Within few minutes
Self-Assembly Formation	Yes
Type of Self-Assembly	Nanotube
Size of Self-Assembled structure	Nanotube diameter varied from 50-250nm
Linear/Cyclic	Linear
Stability of Nanostructure	No notable variation could be observed before and after the incubation of the D-Phe-D-Phe peptide with the enzyme proteinase K (0.02 mg/ml).
Comment	NA
