Peptide Property Calculator Functions

This protein/peptide property calculator is a web-based tool to calculate the peptide chemical formular, net charge at neutral pH, molecular weight, peptide hydrophilicity and hydrophobicity, isoelectric poin and extinction coefficient. The program can predict the hydrophobic or hydrophilic region, secondary structure, transmembrane region, flexible region, surface probability of the input peptide or protein sequence.

Applications

• Calculate and estimate physiochemical properties
• Predict the peptide solubility (See details on how to dissolve peptides)
• Peptide antigen design (See details on how to design peptide antigen)
• Protein concentration calculation (See details on how to calculate peptide concentration)
• Protein protein or peptide protein interaction study (How to detect small peptides by SDS-PAGE)
• Protein structure prediction
• Transmembrane domain or region prediction and study
• Protein profiling
