RAD16-I hydrochloride, a soft nanofibrous self-assembling peptide, is a suitable microenvironment for human mesenchymal stem cells’ (hMSC) proliferation and differentiation into chondrocytes[1]. RAD16-I is a well-studied ionic complementary peptide was used as a model to check potential amyloid-like staining properties of SAPNFs[2].

Details
Negative (lt;0)
1.;;Try to dissolve the peptide in water first. 2.;;If water fails, add NH4OH (lt;50 μL). 3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (gt;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.
