Reconstitution Calculate exactly how much bacteriostatic water to add to your lyophilized peptide vial to hit a target concentration, then read off your syringe draw in units. Open Calculator → Serial Dilution Design multi-step dilution curves for dose-response assays. Calculates concentrations and pipetting volumes for each tube in the series. Open Calculator → Concentration Converter Convert between mass units (mg/mL, mcg/mL, ng/mL) and molar units (mmol/L, µmol/L, nmol/L). Pulls molecular weight automatically from the compound database. Open Calculator → Arrhenius Stability Predicts how long a peptide stays potent at a new storage temperature using the Arrhenius equation — the same math used in pharmaceutical stability testing. Open Calculator → Cost Per Dose Enter a vial price, peptide mass, and your per-dose amount to instantly see cost-per-dose, doses-per-vial, and projected monthly / annual spend. Side-by-side vendor comparison included. Open Calculator → Vial Pooling Aggregate multiple vials into one working stock. Accounts for pipette tip type, fluid viscosity, and transfer loss to give you the true final concentration. Open Calculator → HPLC RT Predictor Estimates reversed-phase HPLC retention time for a peptide sequence based on amino acid hydrophobicity (Kyte–Doolittle scale) — useful for method development. Open Calculator → Mass Spec m/z Predicts ESI-MS charge-state envelopes (m/z peaks) for a peptide sequence. Enter the sequence to see expected [M+H]⁺, [M+2H]²⁺, and higher charge states. Open Calculator → Fmoc-SPPS Cost Estimates solid-phase peptide synthesis reagent cost using Fmoc amino acid prices, coupling cycles, resin load, and scale — useful for budgeting custom synthesis runs. Open Calculator → Solubility Predictor Predicts aqueous solubility of a peptide from its sequence using charge, hydrophobicity, and isoelectric point — flags sequences likely to precipitate. Open Calculator → Vial Quantity Power Calculates how many vials you need to complete a research protocol given a dose amount, schedule, number of subjects, and desired buffer supply.
