• Stability and solubility profiling under laboratory storage conditions

For qualified research professionals and institutional laboratories. Not for human use.


Documentation & Quality Assurance

Each lot is sourced through our verified global supply chain with emphasis on traceability and quality control. We work diligently to obtain and maintain third-party analytical reports (HPLC/LC-MS) and Certificates of Analysis for each batch, as part of our ongoing quality process. These documents are reviewed internally and displayed as they become available. Independent third-party testing is also performed on select lots to confirm identity, purity, and alignment with our internal specifications.


Important Notice

This product is intended for laboratory research use only. It is not intended for human or veterinary use, and must not be used for diagnostic, therapeutic, or clinical purposes.
This material is not a drug, medical device, or dietary supplement, and has not been evaluated by the U.S. Food and Drug Administration.


Quality & Manufacturing

All materials are sourced from carefully vetted domestic and international manufacturing partners who follow quality systems consistent with ISO and cGMP principles. Each supplier is reviewed for reliability, documentation integrity, and transparency in testing.

We require a verified purity of 99% or higher and perform independent third-party spot testing to confirm that select lots meet our internal standards for identity, purity, and composition. Where available, endotoxin testing results are included on Certificates of Analysis to verify laboratory purity; their inclusion is for research quality assessment only and does not imply suitability for human or veterinary use.

All research materials are sealed for integrity and packaged for stability during storage and transport from manufacturing through final delivery.

Storage Instructions

All our research peptides are manufactured using a lyophilization (freeze-drying) process. This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months.

Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days.

Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. This causes the water in the vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure. This powder can be kept at room temperature until reconstitution.

Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods.

Molecular mechanism of Activin receptor inhibition by DLK1.

Nature communications 2025

Delta-like non-canonical Notch ligand 1 (DLK1) influences myogenesis, adipogenesis, and other aspects of human development through a process that is largely attributed to the downregulation of Notch signaling. Here, we show that DLK1 does not bind to Notch receptors or affect ligand-mediated Notch activation, but instead engages the TGF-β superfamily member Activin receptor type 2B (ACVR2B).

Beta-cell adaptation unveiled: The role of myokines in insulin-resistant mice.

Cell reports 2025

To clarify the specific contribution and mechanisms of beta-cell mass adaptation in response to insulin resistance, we took advantage of genetic and pharmacologically induced insulin resistance in mice. We uncovered beta-cell expansion, via an increase in pancreatic islet density, as an adaptive mechanism triggered by mild-to-severe insulin resistance in young and older mice and documented pancreatic adaptation using 3D whole-pancreas analysis.
