Peptide research toolkit
Calculate clearly. Keep every assumption visible.
13 browser-based tools for peptide reconstitution arithmetic, identity, sequence properties, mass spectrometry, document review and laboratory planning. Results show their assumptions and interpretation limits.
Sequence, identity & planning
Peptide-specific tools
Choose a calculation, planning or document-checking tool.
Peptide calculator
Quick reconstitution concentration and final-volume calculations.
Open tool →Peptide sequence analyzer
Sequence composition, mass, pI, charge and hydropathy.
Open tool →Identity & alias checker
Find reviewed names, aliases and molecular identifiers.
Open tool →Peptide stock preparation
Calculate stock mass, volume or concentration with content corrections.
Open tool →Serial dilution & plate plan
Build dilution steps and 96- or 384-well layouts.
Open tool →LC–MS charge-state calculator
Calculate theoretical charge-state and adduct m/z values.
Open tool →Modification mass builder
Apply selected modifications and display their mass deltas.
Open tool →Digestion & fragment map
Generate theoretical cleavage fragments and masses.
Open tool →COA consistency checker
Flag missing or internally inconsistent COA fields.
Open tool →Core arithmetic
General laboratory calculators
Quick mass, volume, molarity and dilution conversions.
Mass concentration
Convert mass and volume into concentration.
Open calculator →Molar concentration
Calculate molarity from mass, molecular weight and volume.
Open calculator →Mass ↔ moles
Convert between mass and amount of substance.
Open calculator →Dilution (C₁V₁ = C₂V₂)
Solve a single dilution step with compatible units.
Open calculator →Confirm identity first
Sequence, terminal form, salt, counterion and conjugation can change the calculation basis.
Keep source precision
The toolkit preserves arithmetic, but significant figures must reflect the underlying measurements.
Export the method trail
Results include a copyable calculation or preparation trail instead of an unexplained number.
