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.

Br-5MP-Propargyl is the derivative of 5-Methylene pyrrolone (5MP). 5-Methylene pyrrolones (5MPs) are thiol-specific, reversible bioconjugation reagents for cysteine-specific protein modification, that are commonly used for protein bioconjugation[1].
