Research Protocols

Common Methodologies for Peptide Research

Innovative Research Labs • Version 1.2 • January 2026

This document provides standardized protocols for common peptide research applications. These protocols serve as starting points and should be optimized for your specific research needs.

Note: These protocols are for research use only. Always follow your institution's guidelines and obtain appropriate approvals for your research.

1Standard Reconstitution Protocol

1Remove peptide from freezer and allow to reach room temperature (15-20 min)
2Clean vial stopper with 70% isopropyl alcohol, allow to dry
3Calculate required solvent volume based on desired concentration
4Using sterile syringe, slowly add solvent along vial wall
5Gently swirl until fully dissolved (do not vortex)
6Aliquot into sterile tubes if multiple uses planned
7Label with date, concentration, and storage conditions

2In Vitro Cell Culture Protocol

1Prepare stock solution at 1mM in appropriate solvent
2Filter sterilize through 0.22μm filter if needed
3Prepare working dilutions in cell culture medium
4Add to cells at desired final concentration
5Include vehicle-only control wells
6Incubate for specified treatment duration
7Assess endpoints as per experimental design

3Stability Testing Protocol

1Prepare peptide solutions at standard concentration
2Aliquot into multiple identical containers
3Store under different conditions (4°C, -20°C, RT)
4At each timepoint, analyze via HPLC or LC-MS
5Compare to time-zero reference standard
6Document any degradation products observed
7Calculate % remaining activity over time

General Best Practices

Always work in a clean, dedicated space

Use sterile, low-binding plasticware

Minimize exposure to light for sensitive peptides

Document all procedures and observations

Include appropriate controls in all experiments

Validate peptide activity before large-scale studies
