BAC Water Essentials
What Is BAC Water?
BAC Water, or Bacteriostatic Water for Injection, is composed of sterile water with 0.9% benzyl alcohol. The benzyl alcohol component acts as a bacteriostatic agent, preventing the growth of most bacteria. This helps maintain the sterility of reconstituted substances over an extended period. In scientific settings, researchers frequently turn to BAC Water when preparing peptides and other biological compounds. Compared to sterile water, BAC Water significantly improves both solubility and shelf life.
3 Key Benefits of BAC Water
- Extended Stability: Maintains peptide stability and sterility for up to 14 days under refrigeration at 2–8°C. This extended time frame allows researchers to conduct prolonged experiments without concern for microbial contamination or reagent degradation.
- Reliable Sterility: Complies with rigorous USP sterility testing for injectable-grade solutions. This ensures that every batch meets stringent cleanliness standards, significantly reducing experimental variability and risk of cross-contamination.
- Optimized Solubility: Improves the dissolution of complex or hydrophobic peptides, streamlining preparation processes. Enhanced solubility reduces the time needed for reconstitution and helps maintain uniform peptide concentration throughout the study.

Ideal Practices for BAC Water Handling
- Vial Preparation: Allow to reach room temperature before opening and disinfect with alcohol swabs.
- Accurate Dilution: Use precision pipettes to mix in correct peptide ratios—typically 1 mg peptide per 1 mL of BAC Water.
- Gentle Mixing: Swirl without shaking to maintain compound structure.
- Proper Storage: Always label the date and contents on vials. Store at 2–8°C and discard after 14 days.
Diving Into IGF-1 LR3
Overview and Molecular Advantages
IGF-1 LR3, or Insulin-like Growth Factor 1 Long R3, is an advanced analog of the natural IGF-1 protein. It has a single amino acid substitution at position 3 and an extended N-terminal region. These changes drastically increase its biological activity and binding affinity, extending its half-life by over 24 hours.
Researchers employ IGF-1 LR3 in experiments focused on cell differentiation, tissue regeneration, and metabolic studies. A comprehensive discussion on the signaling mechanisms of IGF-1 can be found in this Nature Reviews Endocrinology article.
Five Benefits of IGF-1 LR3 in Research
- High Potency: Demonstrates up to 3x the biological activity of native IGF-1, delivering heightened efficacy in cellular stimulation and proliferation pathways. This improved potency helps researchers observe more pronounced outcomes, even at lower concentrations.
- Longer Half-Life: Remains functional in assays for over 24 hours, enabling extended experiments without frequent intervention. This prolonged half-life ensures continuous interaction with receptors, especially in time-sensitive or kinetic studies.
- Reduced Dosing: Requires fewer re-doses across assay timelines, thereby improving experimental consistency and minimizing the margin of human error. This also reduces the cumulative reagent use, which is especially valuable in budget-sensitive research projects.
- Enhanced Signal Clarity: Triggers clearer and more consistent receptor signaling cascades. This leads to stronger data reproducibility and a more precise understanding of mechanistic responses in pathways like PI3K/Akt and MAPK.
- Versatile Applications: Extensively used in regenerative medicine, oncology, and metabolic research models where cellular regeneration, anti-apoptotic behavior, and glucose metabolism are critical study areas. IGF-1 LR3’s adaptability makes it a core reagent across multiple fields of research.
Handling and Storage Protocols
- Reconstitution: Reconstitute with chilled BAC Water or sterile water.
- Aliquoting: Create single-use aliquots to avoid peptide degradation due to repeated freeze-thaw cycles.
- Ultra-Low Storage: Store at −80°C and protect samples from light exposure.
- Thawing: Rapidly thaw in a 25°C water bath and immediately place on ice before use.
Protocol Standardization for Reproducibility
Develop a Unified Workflow
Consistency across protocols ensures reproducibility. Labs should create detailed manuals outlining every procedure—from reagent reconstitution to assay execution. Standardization boosts result reliability and minimizes errors during inter-lab collaboration.
Monitor Purity with QC Tools
High-performance liquid chromatography (HPLC) and mass spectrometry (MS) are vital tools to confirm compound purity. These techniques help eliminate batch contamination or degradation.
Training and Documentation
Quarterly training sessions help lab staff stay updated on best practices. All reagent handling should be logged meticulously in notebooks or digital lab software. This documentation supports audit readiness and improves experimental accuracy.

Regulatory and Safety Considerations
Compliance and Labels
Modern Aminos clearly marks all its products as “Not for Human Consumption.” The labeling aligns with FDA CFR Title 21 guidelines governing chemicals used in research settings. Researchers should always reference MSDS sheets before product usage.
Safe Laboratory Practices
- Always observe biosafety level standards relevant to your specific experiments, ensuring compatibility with both institutional and national safety frameworks.
- Use appropriate waste disposal protocols that adhere to both environmental regulations and institutional compliance standards, avoiding chemical contamination.
- Equip yourself with proper personal protective equipment (PPE), including nitrile gloves, lab coats, and chemical-resistant goggles to guard against accidental exposure.
- For added biosafety, always conduct sensitive reagent work inside a Class II biosafety cabinet or a chemical fume hood to reduce aerosol exposure and safeguard sample integrity.
