Show Protein Properties

How do I view predicted molecular weight, extinction coefficient (A280), absorbance (A280), isoelectric point, charge and the amino acid count for a protein sequence?

SnapGene uses the method of Grimsley et al, 2009 ( to calculate Isoelectric point.

Open or Create a Protein Sequence

Switch to the Properties view.

Click the disclosure triangles to see details of predicted Properties.

Click the dropdown to calculate predicted charge at different pH values.
